Prebuilt Uber-Style App Solution

I’m ready to launch a ride-hailing service and want to start from an already-built, thoroughly tested code-base rather than building from scratch. I need a white-label app that runs smoothly on both iOS and Android and can be re-skinned with my branding, colours, and language settings.

Essential features I expect to see working out of the box:
• Payment integration (cards, wallets or any widely-used SDK you already support)
• Real-time GPS tracking for riders and drivers
• User ratings and reviews after each trip

Please include a detailed project proposal that explains:
– The current tech stack and architecture of your solution
– Any third-party services or licences it relies on
– How you will customise the UI/UX, payment gateway, and backend settings for my market
– Timeframe for branding, testing, and submission to the App Store and Google Play
– Post-launch support or maintenance packages you offer

A short demo video and links to live builds or TestFlight/Android test installs will help me assess stability and user experience quickly.
