Hi Developers, My existing project is disputed (Started Before 1Year) and got me the WIN from freelancer disputation due to my last seller's delivery issue.

Payment gateway integration (Google Play+Apple Pay+Ideamart Sri Lanka Subscription) 3. Host and Publish the App 4. Show the RIGHT Last Location when close the app (GPS OFF) 5. Show the RIGHT Location when close the app (GPS ON) 6. Show the RIGHT Battery Percentage and Location when close the app 7. Show Saved Contact Name instead of showing users profile name 8.
