Write some software -- 3

I need you to develop some software for me. I would like this software to be developed for Mac using C or C++. Electronic boost controller and turbo timer for turbocharged Cars that is controlled by a mobile app for iPhone and android . (If you don't know what a Electronic boost controller and a turbo timer is please don't contact me) This is driven through a Atmega328p from a arduino. I need a code that does the following: Electronic Boost controller -6 programmable settings -ability to set boost anytime -1-100psi -6 programmable boost cut/fail safe feature (user sets this setting ) Turbo Timer -4 programmable settings -ability to set a temporary timer - ability "to stop" turbo timer - .00 seconds - 2 minutes - handbrake shut off safety feature *** the code should work off last presets in case the phone is dead *** App - Splash screen - Background running - - 3 programmable settings for turbo timer - 3 programmable settings for boost pressure - Display real time pressure readings - Display turbo timer - Display selected preset boost settings -Display selected turbo timer settings - Turbo timer countdown - Notifications when timer starts and finish
