Flutter, by default.

Tighter tooling than RN, predictable rendering, mature native module ecosystem. RN if you specifically want it.

// 05 — WHAT'S INCLUDED

Five things every custom app needs.

Auth, push, offline, native modules, OTA. Default-on, scoped to brief. Add anything specific in discovery.

01

Auth + role-based access

Phone OTP, social login, biometric. Roles per screen, server-validated.

02

Push + transactional

FCM topic + targeted. Booking confirmations, reminders, marketing — your call.

03

Offline-first

Local queue + background sync. Works on subway, plant floor, hill stations.

04

Native modules

Camera, scanner, biometric, NFC, Bluetooth printer. Whatever the brief needs.

05

OTA updates

Push UI fixes without store review. Native code via store, content via OTA.

// 07 — TYPICAL TIMELINE

Brief to both stores — under 12 weeks.

Backend setup overlaps with design phase. Store review adds 5–7 days unpredictable — we plan for it.

// 10 — APP QUESTIONS

Flutter, stores, reviews.

Apple's 30%, Play Console quirks, OTA scope — all the things app agencies skip.

Flutter has tighter tooling (single binary, hot reload, predictable rendering), and a stable native-module ecosystem. RN is good too — if you specifically want it, we'll build with it. Default is Flutter.
