Fra 357,557 tilbakemeldinger, klienter rangerer våre Android Developers 4.9 av 5 stjerner.I’m putting together an Android Studio app whose only job is to pull product records from a Postgres instance hosted on Google Cloud and show them in a clean, scrollable list. The data connection must run through Google’s Antigravity agent so the app stays lightweight and secure without shipping database credentials inside the APK. Here’s what I need from you: • A minimal yet solid Android Studio project (Kotlin or Java—your choice) that connects to the Postgres database via the Antigravity agent. • An async call that fetches product data—name, price, description, image URL are enough for a working demo—and maps it into a RecyclerView list. • Basic UI: toolbar with app name, RecyclerView list, placeholder images handled gracefully, a...
I need a secure, web-based application that streamlines every key workflow in my optics practice. The core of the platform is an electronic patient record that stores medical history, insurance information, and prescription records in one place, searchable at any time from any modern browser. A dual-mode recall engine must be built in: it should send automated SMS and email reminders while still allowing staff to step in and schedule manual follow-ups whenever needed. The same messaging layer will power day-to-day email and text communication with patients. To keep the team organised, the system also requires an integrated to-do list where tasks can be created, assigned, and tracked through completion. Deliverables • Responsive web interface with role-based access • Databa...
I run a small clinic and need a straightforward mobile application that lets my team capture, store and pull up a patient’s complete medical history at any moment. The heart of the build is a structured medical-history module linked to a prescription writer, so a doctor can open a chart, review past notes, add today’s findings, then generate and save a new prescription—all from one screen. The app has to work smoothly on modern smartphones, store data securely on-device first, and give me an easy way to back up or export records (PDF for individual visits and CSV/JSON for bulk data). A quick search by name, phone number or patient ID is critical because we often look up a file while the patient is sitting in front of us. Appointment scheduling is not a must-have right no...
Facing issues in existing Weighbridge application who is connected with RFID Reader and CCTV camera , I need a IOT Developer who can fix the existing RFID reader and CCTV camera issue and make this application flawless . This application made in Dot Net and work with Laravel application, application works in offline and sync the data into online.
I have a clear idea of the problem my app should solve but, instead of a formal brief, I will give you a set of reference materials—competitor apps, feature lists, and a few rough sketches. Your first task is to study these assets, extract functional requirements, and translate them into a structured roadmap. Once we agree on the roadmap, you will design the UI/UX, recommend the most suitable tech stack (native iOS, native Android, or a cross-platform framework), and then build, test, and package the application. Code must be clean, well-commented, and committed to a shared repository so I can track progress in real time. Deliverables: • Requirement summary distilled from my references • Wireframes or a clickable prototype for sign-off • Full source code with bu...
Based on the image you sent from the Freelancer app ("Tell us what you need done"), the text you should type into that empty box depends on what kind of project you want to post. Here are a few options you can copy and paste depending on what you need: —————————— Option 1: If you want to hire someone to edit a photo (like the church photo you mentioned earlier) I need a professional photo editor to edit a church photo. I want you to remove the background trees, replace them with a nice dramatic sky, enhance the lighting and colors, crop it nicely, and deliver a high-quality final image. —————————— Option 2: If you want to hire a Graphic Designer (Logo...

I have a Google account ready, all personal details prepared, and I will supply every OTP that pops up during the flow. What I cannot provide is an internationally-enabled debit card, which is where you come in. Your task is to take my account from “start registration” to a fully active Google Play Console developer account. The payment must be made with a debit card that supports international transactions, and the whole session needs to run behind an Indian IP to avoid region-related hiccups.

I’m gearing up to launch a brand-new Android app that lets my hardware-shop customers browse products, add items to a cart, and place orders straight from their phones. The focus is strictly on online sales and ordering—no inventory management module for now—so every screen should guide shoppers smoothly from discovery to secure checkout. Core flow I need: • Product catalogue with categories, search, photos, prices and live stock count pulled from our existing SQL database (REST/JSON endpoint is ready). • Cart, quantity edits and promo-code field. • Checkout supporting cash-on-delivery plus at least one standard payment gateway (Stripe or Razorpay is fine). • Order confirmation, push notification updates and a simple order-history screen. &bul...

I need a complete Android-only mobile app built from the ground up for my project, Jamzith ja. The core idea is defined, yet the feature set still needs to be refined and transformed into an intuitive, production-ready experience.

I want to launch a task-marketplace similar to Airtasker that ships on iOS and Android at the same time, so a single cross-platform code-base is essential. Users must be able to create an account instantly with Apple, Google or Facebook, post a job, receive bids, choose a worker, pay safely, and leave feedback once the work is done.

I will send link just to download app
I’m creating a self-guided, two-hour tour that visitors can enjoy even when they have no signal, so every asset—audio tracks, video clips, map tiles, and imagery—must be packaged inside the app bundle and run 100 % offline once the first download completes. Core experience • As soon as the phone’s GPS detects that a traveler has reached a designated point, the matching chapter should start automatically. • Users can still tap Play or Pause at any time, scrub the timeline, or replay earlier chapters if they wish. • An interactive map (shown with the device’s live position) remains available offline and lets users jump to any stop visually. • Short quizzes or checkpoint questions pop up at selected locations to keep people engaged an...
I’m rolling out a consumer-facing mobile app and need a tester who is physically in the Philippines—Metro Manila preferred—and already has an active PH phone number. You’ll install the current build on both an Android and an iOS device you own, then walk through the full experience while we watch and discuss over a scheduled video call (Zoom or Google Meet, whichever you like). During the session we will: • review the user interface for visual or layout issues on each platform • exercise every primary function, flagging bugs or confusing flows • note any performance hiccups such as slow loads or crashes Afterwards, please send a concise report (screenshots, short clips, and step-by-step notes) summarizing what you observed, grouped by UI, fu...
I need a pair of polished mobile apps—one for iOS, one for Android—that lets a traveler open the phone, find a human agent, and finish a booking in a few taps. The entire flow should feel like messaging a knowledgeable friend: the user starts a chat, describes the trip, then reviews flight and hotel options surfaced through live API feeds before paying securely inside the app. Core experience • Dual-platform build (iOS + Android) delivered either natively or with a single codebase such as Flutter or React Native—whichever you recommend for long-term stability and speed. • Real-time messaging between traveler and assigned agent, complete with push notifications and image/file share. • Integrated flight and hotel search tied to a major GDS/OTA API so a...

I’m expanding my Mobile Legends project with a dedicated Ranked mode focused on ranking and rewards. The core gameplay is already in place; this task is strictly about building the ranked layer so players can climb tiers, earn season-end prizes, and track progress match-to-match. Scope of work • Design and document a ranking algorithm that updates after every match in Ranked mode. • Implement persistent player data storage (Firebase, PlayFab, or a comparable backend) so ranks and stats carry across sessions. • Code the reward distribution logic for daily, weekly, and season-end payouts, following the typical Warrior-to-Mythic tier structure. • Provide a functional prototype (Android APK plus commented source) that integrates seamlessly with the existing mat...

I need a native-Android application that reproduces the workflow now handled in my Excel sheet. The sheet records every job, lets the person doing the work enter his direct costs, and then helps me track what has already been paid and what is still outstanding. I want the same data-entry fields and the same automatic calculations migrated into an intuitive mobile interface so nobody has to touch the spreadsheet again. Two distinct roles are required. • Job performer: opens the app, chooses or creates a job, keys in labour, material or travel costs and immediately sees the calculated total for that job. • Manager/Administrator: sees every submitted job, the running balance of payments, marks items as paid, and can export a simple summary report for accounting. Core features ...

I run a building–material wholesale operation and need a cross-platform mobile app (native or well-built hybrid) that lets me keep every stakeholder, from retailers to on-site masons, fully informed and motivated. Retailer module • Retailers log in to record each sale of my products. • The system automatically tallies their sales history and shows real-time overdue balances so both sides always see the same numbers. • I can adjust or upload credit notes, payments received, and comments from an easy web or admin panel, with instant sync to their phones. Mason / builder loyalty module • Every time a mason lifts material from a linked retailer, the retailer records the quantity; the app assigns reward points based on my rules (I should be able to edit multi...

I’m developing a mobile-first social networking platform that will run on both iOS and Android. Core features include profile creation, follower/friend connections, a real-time feed with likes and comments, private messaging, push notifications, and media upload for photos and short videos. A clean, modern UI/UX and smooth onboarding (email, phone, or existing social sign-ins) are priorities, and the codebase should be structured for easy scaling and future feature releases. Cross-platform frameworks such as Flutter or React Native are perfectly acceptable as long as performance matches native expectations; if you prefer fully native builds, outline the benefits you can bring. A lightweight backend/API and basic admin dashboard are also part of the scope, though I’m open to re...
Run a quick end-to-end check of our live Hutch mobile service using a Hutch SIM physically located in Sri Lanka. You may use either an Android or an iPhone—whichever is easier at the moment—and rely on the phone’s built-in screen recorder so the video shows every tap, SMS, and the Hutch network indicator throughout. The flow is simple: 1. Subscribe to the service through one of the live portals: 2. Immediately unsubscribe. 3. Save the raw, unedited recording. Acceptance criteria • Network indicator clearly shows Hutch at all times • Full subscription journey, each SMS sent/received, and the unsubscription confirmation are visible without cuts or skips • Raw video file is shared, plus a brief two-to-three-sentence note stating the time ...
I’m looking to build a brand-new application from the ground up. The exact platform—mobile, web, or desktop—can be decided once we discuss the best fit for the core concept. At this stage I need an experienced developer who can guide the entire lifecycle: • Clarify requirements and translate them into user stories • Recommend the most suitable tech stack and architecture • Provide wireframes or quick mock-ups for key screens • Develop a clean, well-documented MVP in a Git-based repo • Package the app for deployment and hand over basic run instructions If you have full-stack experience, a strong grasp of UI/UX principles, and a history of delivering complete applications, share links to two or three relevant projects along with an outline...
We need an independent security review of a new member app (React Native / Expo) and its PHP JSON API. This is not a redesign or a feature build. The previous generation of this product had a serious incident (personal data exposed). That stack is retired. We want a review of the new app and API before a wider release. This is a small member app for people who already belong to a venue/club. It is not a marketplace, social network, or payments app. What it does today (this is the whole product): - Sign in, create account, verify email, reset password (reset is a simple web page) - 8 languages - Accept terms when they change - Home: greeting, shortcuts; optional club “home” when a club is selected - Clubs: list of linked clubs, pending/unavailable states, add a club with a co...
I’m looking for a complete, browser-based Rummy experience that lets players sit at live tables and play for real money. The game must run smoothly on any modern desktop or mobile web browser, with no downloads required, and support real-time multi-player matchmaking so users can join, leave, and re-enter tables without refreshes or lag. Key goals • Real-cash play: a secure wallet system for deposits, withdrawals, and in-game stakes. • Seamless multiplayer: synchronous gameplay with accurate card distribution, turn timers, reconnection handling, and anti-collusion checks. • Intuitive interface: responsive design, smooth animations, and simple onboarding so first-time players understand the rules quickly. • Fairness & security: verifiable RNG, encrypte...
Build me a Free Fire Tournament App
I need an app that mirrors Biyajkhata’s customer-management flow while running natively on both iOS and Android. The reference app already covers the core screens and logic, so your main focus will be recreating that experience and adding two important extras: • Key numbers panel – a quick snapshot of each customer’s outstanding balance, paid amount, and upcoming due date. • Universal name search – a fast search bar that lets users find any customer from any screen in real time. A cross-platform framework such as Flutter or React Native is fine, provided the final builds are smooth on modern and older devices alike. I’ll share Figma wireframes at project start; you’ll handle coding, basic UI styling consistent with Biyajkhata, and produce p...
Workspace ONE UEM / MDM Engineer Experience: 8–20 Years Employment Type: Full-time / Contract / Freelancer/ Location:- India /Saudi Job Description We are looking for an experienced Workspace ONE UEM / MDM Engineer to design, implement, and support an enterprise Workspace ONE environment. Key Responsibilities Design and deploy Omnisa Workspace ONE UEM in a hybrid, HA/DR and secure DMZ architecture. Manage Windows, iOS, Android, macOS and other enterprise devices.

I’m spinning up a new enterprise deployment of Omnissa / VMware Workspace ONE and need a senior engineer who can own the entire UEM lifecycle from architecture through steady-state support. The environment spans Windows, iOS, Android and macOS devices, so you must be equally comfortable writing custom profiles for iOS as you are managing Windows patch rings or Android Work Profiles. Beyond the core console work, deep integration with the following is critical: • AD, Exchange, PKI, certificates, VPN High-availability design, DMZ and firewall rule-sets, unified application cataloguing, device enrollment flows, compliance policies and large-scale production rollouts all fall inside the scope. You will document everything you build and walk my internal admins through the solu...
I’m days away from releasing a brand-new Android app and need a person with at least 12 Gmail accounts to help test it either on your phone or laptop. Once we start, I’ll share the APK through a Gmail-accessible link, a concise usage guide, and a feedback template. Here’s what I’m after: • Install the build on your everyday Android smartphone and, if you have one handy, a tablet as well so we can see how the UI scales across form factors. You can also open it on an emulator or desktop tool for extra checks, but that’s optional. • Explore every screen, trigger every button, and deliberately push each workflow until you’re certain it behaves—or misbehaves. • Capture notes on the three areas I care about most: User Interface quirks, C...
I am launching a scalable e-commerce marketplace and need the complete mobile application built for both iOS and Android. The first milestone centres on three core capabilities that must be production-ready from day one: • Secure user authentication – email or social sign-in, token refresh, and logout flows handled safely. • Seamless payment gateway integration – in-app checkout that passes all compliance tests and returns clear transaction states to the UI. • Product reviews – verified purchasers can post ratings and comments that update instantly across devices. Wireframes and an API (REST/GraphQL) are already in motion, so your focus will be the full mobile build, state management, and preparing store-ready releases. Clean architecture, modular c...
I need help verifying how my Android app behaves when it just sits in a user’s pocket. The focus is narrow: measure and document idle state battery drain. To do this properly you’ll sign in with several different Gmail accounts (the app offers account-based personalisation), leave the app installed on one or more physical Android phones, and capture how much power it quietly consumes over set time windows. Here’s what I’m expecting from you: • A clear test plan that shows the steps you’ll take to track idle consumption (e.g., using Android Battery Historian, adb shell dumpsys batterystats, or similar tools). • Screenshots, raw logs, and a concise written summary that spotlights any abnormal drain compared to baseline device usage. • Note...
I need a fully working mobile application that converts plain-language prompts into accurate SQL statements and is ready to ship on both iOS and Android. The user flow is simple: type or paste a question such as “show me all orders placed this week,” tap a button, and instantly receive a correctly formatted SQL query. From there the query should be easy to copy, share, or save. Cross-platform consistency is essential, so the build must target iOS and Android from the same codebase. React Native or Flutter are both fine; feel free to suggest an alternative if it still produces App Store- and Google Play-compliant release builds. Core requirements • Clean text input with real-time or on-tap SQL generation • Support for at least the major SQL dialects (MySQL, Postgre...
I need an experienced Minecraft server developer to build a complete custom Survival server, inspired by servers like Guarópolis but more complete, polished and professionally structured. The main goal is to preserve the normal Minecraft Survival experience (Vanilla+) while adding useful multiplayer features and progression systems. I do NOT want a heavily modified RPG server. Players should still feel like they are playing normal Minecraft: mining, building, exploring, farming, fighting mobs, trading and surviving. Core requirements: - Custom Survival / Vanilla+ server - Modern Minecraft version - Paper or Purpur preferred - Professional spawn - Land claiming and grief protection - Economy system - Player shops - Auction House - Jobs/professions - Quests and challenges - Player sta...
I want to release a clean, lightweight GPS running tracker built exclusively for Android. The app’s single non-negotiable is rock-solid, real-time location tracking that draws the runner’s path on a map and keeps accurate distance and pace figures throughout the session. I’m aiming for something dependable enough for everyday use, yet simple enough to feel snappy on mid-range phones. Here’s how I picture the flow: • User taps “Start” and the route begins drawing instantly on a Google Map. • Live stats (time, distance, current pace) update each second. • Hitting “Stop” saves the run to a local store; I’m open to your recommendation on whether to sync it later to Firebase, Room, or another lightweight option. Core expecta...
