Overview

What “Mobile Apps” means at Devmint.

Mobile App Development at Devmint means shipping iOS and Android applications that feel native, perform well on real devices and survive the App Store and Play Store review cycle without surprises. We build in React Native and Expo for cross-platform speed, in Flutter where the product demands it, and natively in Swift or Kotlin when the experience truly requires it. We've shipped consumer apps, B2B tools and a hypercasual game on Google Play — the discipline is the same in all three.

Most mobile projects we audit lose time to the unglamorous middle: deep links, push notifications, in-app purchases, offline state, analytics, crash reporting, store metadata, signing certificates. Devmint engagements treat that middle as the project, not the afterthought. You get an app that launches on time, gets approved on the first submission, and has the telemetry to tell you what users actually do once they install it.

What you get

Deliverables.

iOS + Android app (RN, Flutter, or native)
Auth, push, deep links, in-app purchases
Offline-first state where it matters
Store-ready assets + first-submission approval
Crash + analytics instrumentation

How it ships

The shape.

Mobile engagements run 8–14 weeks. Discovery + spec week → 6–10 build weeks with weekly demos → store-ready assets + first-submission approval as a deliverable, not a hope.

Investment

How we price.

Devmint engagements are scoped as fixed proposals against measurable outcomes — not hours. After a 30-minute discovery call, we send a written proposal with timeline, deliverables, eval targets and a single fixed fee. No procurement maze, no T&M creep. Smaller pilots and larger outcome-based contracts are scoped the same way — tell us what you're shipping and we'll come back with a number.

Tech stack

What we reach for.

React Native + Expo by default · Flutter or native Swift/Kotlin when the experience demands it · Firebase + Sentry · in-app purchases via RevenueCat · push via Expo or OneSignal.

FAQ

Common questions.

React Native, Flutter or native — how do you choose?

React Native + Expo by default — it covers about 80% of products with a single codebase, a strong third-party ecosystem and faster iteration. Flutter when the design language demands its rendering model. Native Swift or Kotlin only when the product needs a platform capability that costs more to bridge than to write twice. The choice is made in writing during scoping, against measurable trade-offs.

Will the app get approved on first submission?

Approval-on-first-submission is treated as a deliverable, not a hope. Devmint owns App Store and Play Store metadata, signing certificates, privacy declarations, deep links, push setup and the in-app-purchase configuration before the binary is uploaded. The result is a calmer launch week.

Does the build include push, in-app purchases and analytics?

Yes. Push notifications, deep links, in-app purchases via RevenueCat, offline state where it matters, crash reporting via Sentry, and event analytics from day one. The unglamorous middle is the project — not the afterthought.
