App development company in Patna — Android & iOS
Chapterfeed builds Android and iOS apps with React Native — one codebase, both stores. Backed by secure APIs in Spring Boot, FastAPI, or Node.js, and managed cloud infrastructure that stays up.
What we build
- Coaching & learning apps — for schools, tutors, and coaching institutes (see TrulyMentor Academy).
- Business & billing apps — invoicing, ledger, GST-friendly tools (see Smart Raseed).
- Marketplace & booking apps — two-sided platforms with profiles, search, payments, and admin (see Atom Home Tuition).
- Customer-facing brand apps — loyalty, ordering, content, and community apps for D2C and service businesses.
- Internal tools — field-force apps, attendance, sales, and inventory tools for SMBs.
Why React Native
For most apps in our segment — coaching, billing, marketplaces, brand apps — React Native gives you near-native performance, one codebase for Android and iOS, and faster shipping cycles. Native modules are still possible when a feature genuinely needs them. We won't push React Native if your app needs heavy real-time graphics or deep OS integration; in those cases we'll recommend native Kotlin or Swift instead.

Common questions
Can you publish to Play Store and App Store on our behalf?
Yes. We handle store submissions, listing assets, and review iterations. You own the developer accounts.
Will the app work offline?
Where it makes sense, yes — we design for spotty Indian network conditions and queue-and-sync where possible.
Do you build native iOS/Android instead of React Native?
Yes, when the app genuinely needs it. We'll recommend the right path during discovery.
Do you provide hosting and ongoing support?
Yes — managed VPS, monitoring, and maintenance. See hosting →
