Android + iOS app for GPS tracking & more

Stage 1. Basic track measuring for cars - similar to Endomondo. -Start + stop -Measure track (avg speed, max speed, distance, time) -Tracks are synchronized with server (API is ready) -When track is measured app should be a service (also available from the status bar to quickly see elapsed time and easily go back to the app) -When start is pressed app waits for movement (instead of showing distance + time it says 'waiting for movement'), when the car reaches min. 10km/h measurements are started (can be circa 10km/h) Stage 2. Basic achievments (game like style): -User earns achievments by reaching goals like: total distance, total distance in one track, total distance in next xx days, min. avg. distance every day for xx days -Every achievment gives points needed to gain xp/another 'level'. -Some achievments are the same all the time, but levels up (e.g. total distance lvl 1: 10km, lvl 2: 25km, lvl 3: 50km), some are one time only (ask 5 friends to the app, reach a specific point, win 5 challenges-more about challanges in stage 4.) Stage 3. Social: Login / register - email + pass or facebook Photo / name / short info about a car the user drives Find your friends (facebook, contact book) + share In-app contact list (based on the above friend find, like in Viber etc.) Push notifications (challenge accepted-stage 4, invited to event-stage 5) In-app advestisments Stage 4. Challenges: -Create or join challenge (public challenges or invite only challenges=share or choose from in-app friends) -Date & time of start + end -Options for challenges: total distance, total distance in one track, highest speed, 1st user to reach xx km, 1st user to reach xx km/h, 1st user to reach certain point. -Can search for global challenges / nearby / private (to which the user is invited) More details can be discussed in private. These 4 stages are a complete minimum for the app to run. There are more stages later on, so we are looking forward for a longer cooperation.
