Engaging mobile experiences for iOS and Android
Mobile App Development
We design and build mobile apps that people keep on their home screen, from native iOS and Android to cross-platform Flutter and React Native.
Who this is for
Mobile engagements suit companies that need an app on both stores with a real backend, not a wrapped website. Buyers are typically consumer startups, businesses adding a companion app to a web product, and operations teams equipping drivers, technicians or field staff.
- Founders launching a consumer or marketplace app on iOS and Android at the same time
- SaaS companies adding a mobile companion app that shares the existing API
- Operations teams that need offline-capable apps for staff in the field
- Companies rewriting two ageing native apps into one maintainable codebase
How we approach mobile app development
We recommend Flutter for design-heavy consumer apps and React Native when your web team already works in React; native Swift and Kotlin are used where hardware access or platform-specific behaviour demands it. Every project starts with a clickable prototype tested on real devices, then moves into two-week sprints with a TestFlight or internal Play build at the end of each one, so you use the app on your own phone from week three.
Backends are built or extended alongside the app with versioned APIs, push notifications, deep links and analytics wired in from the start. Testing covers a physical device lab plus BrowserStack across the current and two previous OS versions, and offline sync is designed explicitly rather than bolted on. We manage App Store and Google Play listings, review submissions and phased rollouts under your developer accounts, and monitor crash-free rates after launch.
What a typical engagement looks like
| Phase | Duration | What you get | Typical cost |
|---|---|---|---|
| Strategy and prototype | 1 to 2 weeks | Feature scope, clickable prototype, store requirements, fixed estimate | $3k to $8k |
| MVP app (both platforms) | 10 to 16 weeks | Core features, backend, push, analytics, store submission | $20k to $45k |
| Full product | 5 to 8 months | Payments, offline mode, integrations, admin panel | $60k to $150k+ |
| Store launch and growth | 2 to 4 weeks | Listings, screenshots, phased rollout, crash monitoring | Included |
| Maintenance | Monthly | OS updates, store compliance, improvements | $1.5k to $6k per month |

Mobile Apps questions, answered.
Flutter or React Native, which should we choose?
Both ship to iOS and Android from one codebase. We usually recommend Flutter for design-heavy consumer apps and React Native when your web team already works in React.
How long does it take to build a mobile app?
An MVP typically takes 10 to 16 weeks from kickoff to store submission. Larger apps with custom backends run 5 to 8 months.
Do you publish the app to the App Store and Google Play?
Yes. We handle store accounts, listings, screenshots, review responses and release management.
