MVP in 6-8 weeks. Apps with more features, 12-16 weeks. App Store review: 1-2 weeks for Apple, 2-4 hours for Google Play. Total: budget 4-5 months from start to live stores.
Do you include post-launch support?
Yes. 3 months of maintenance and support included. After that, we offer monthly plans ($2K-5K USD) for iOS/Android updates, bug fixes, and new feature development.
Does the app include push notifications?
Yes, push notifications are standard. We integrate Firebase (Android) and APNs (iOS). We can segment users, schedule campaigns, and track engagement.
Can I use social login (Google, Facebook)?
Absolutely. Social authentication is recommended—faster user signup, higher conversion. Google, Facebook, Apple Sign-In all supported. Also includes traditional email/password.
Do you deliver the source code?
Yes, complete source code, git repository, build configs, and API documentation included. Full ownership transfer. You can continue development with any team or modify endlessly.
Who owns the app and intellectual property?
