Cross-platform development
Flutter or React Native apps that feel native on both platforms from one shared codebase.

Mobile apps for iOS and Android, built once and shipped fast
Sharp Minds builds cross-platform mobile apps with Flutter and React Native so you reach iOS and Android users from one codebase, roughly 40 percent faster than two native builds. Backend, push notifications, payments, analytics and store submission are handled by the same team.

How long does it take to build a mobile app?
A focused first version with authentication, a core workflow and push notifications takes 8 to 12 weeks from kick-off to store submission. Simpler companion apps take 4 to 6 weeks, and apps with complex offline logic, hardware integrations or marketplaces take three to five months. We demo on real devices every week.
What is included
Native iOS & Android
Swift and Kotlin when performance, hardware access or platform features demand it.
Backend & APIs
Scalable APIs, authentication, real-time features and admin panels to run the app.
Payments & subscriptions
In-app purchases, Stripe, Apple Pay and Google Pay integrated and tested.
Release management
App Store and Google Play set-up, review submissions, beta testing with TestFlight and Play Console.
Analytics & crash reporting
Firebase, Sentry and product analytics wired in from the first build.
What does the process look like?
A short discovery phase that fixes scope and price, then weekly increments you can see and test.
- 01Weeks 1-2
Product & UX
User flows, wireframes and a clickable prototype validated with a handful of users.
- 02Week 3
Architecture & API
Data model, API contract and CI pipeline that delivers builds to your phone automatically.
- 03Weeks 4-9
Feature sprints
Weekly builds on iOS and Android, tested on real devices with your feedback fed into the next sprint.

Store release
Hardening, store listings, screenshots, review submission and launch monitoring.
How long does it take?
Typical durations and team sizes for common scopes. Discovery confirms the exact plan before we start.
| Scope | Duration | Team |
|---|---|---|
| Companion or utility app | 4-6 weeks | 1 mobile developer, 1 designer |
| Consumer app with backend and payments | 8-12 weeks | 2 mobile developers, 1 backend developer, designer, QA |
| Marketplace or enterprise field app | 3-5 months | 3-4 developers, designer, QA, delivery manager |

Questions about this service
01Flutter or React Native, which should we choose?
Flutter is our default for new consumer apps thanks to its rendering performance and consistency. React Native makes sense when your web team already works in React and wants to share code and knowledge. We recommend one after a short technical call.
02Can you take over an existing app?
Yes. We start with a code and store-health audit, fix stability issues first, then plan the roadmap. Taking over both the app and the backend is common.
03Do you handle App Store and Google Play submission?
Yes, including developer account set-up, listings, privacy declarations and review follow-ups, until the app is live.
04What about ongoing maintenance?
Operating systems and store policies change several times a year. We offer monthly maintenance plans that cover updates, monitoring and small improvements.
