Ios app development

we are looking for a movesense developer. We already have this developer kit (search it on web). We need to produce an app for Movesense that transmits heart rate and temperature in real time to a deshboard like this attached (left and center diagram). Upgrades via bluetooth must take place every 5 seconds. The app must be able to configure a trigger when the heart rate, and the temperature, exceeds or falls below a certain threshold. Then you will need to be able to configure: "HR - maximum threshold:" "HR - minimum threshold:" "Temp - Maximum Threshold:" "Temp - minimum threshold:" When one of these events occurs, the client thats Movesense is connected, will have to call back a user-defined http URI (via curl, wget, as you like) in the background. You can use any technology you feel most essential as you wish. The client can be for Windows, or for Android, or for IOS. How do you feel appropriate. Just, you have to first specify which programming language you will use. All source code will be issued, which will have to be well commented in English. if you can't do this for $50 .. Don't mesaage me because you will not be considered
