FAQ
Do all three platforms (Android, Web, Windows) sync the same data?
Yes. The application is integrated with a centralized cloud database (such as Firebase or Supabase), ensuring that actions taken on mobile, web, or desktop reflect across all devices in real time.
Can you help with Google Play Store upload and Web hosting?
Yes, store submission support (generating signed release bundles and setting up store listings) and cloud web deployment (Firebase or Cloudflare) are available as gig extras.
What do I need to get started?
Please share an overview of your app concept, key workflows or screens needed, branding assets (logo/color preferences), and any specific hardware or API requirements (like thermal printers or third-party services).
