App development for web, mobile, and everything in between.
App development in 2025 means React on the web and React Native on mobile — the same component model, the same TypeScript patterns, different deployment targets. A developer who knows both can build your full product.
Need to build an app — web app, mobile app, or both
"App" means different things to different founders:
Web app: Runs in the browser. URL-addressable. No app store. Deploy via Vercel. Accessible on any device with a browser. Best for: SaaS products, tools, dashboards, platforms.
Mobile app (native): iOS App Store and Google Play. Requires device (not just a browser). Access to camera, GPS, push notifications, biometric auth. Built with React Native/Expo.
Progressive Web App (PWA): Website that behaves like an app on mobile — installable from the browser, can use some device features. Middle ground between web and native.
The typical startup path:
- Web app first (faster to build, works on all devices, no app store approval delay)
- Mobile app when: users expect native, the core feature requires native capabilities, or the audience is mobile-first
When to build mobile first:
- Social/consumer app where the audience is mobile-native
- App requires camera, GPS, or background processing
- The app store provides discoverability for the market
The shared backend: Both web and mobile apps use the same backend API. Building the web app first doesn't waste the backend work — the mobile app uses the same API.

One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.
App built and deployed: web on Vercel, mobile on iOS App Store and Google Play
Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
App scope is the platform targets and the feature set. Fixed-price per platform.
Questions, answered.
Mobile adds: native build tooling, app store submission process, platform-specific UX patterns. Estimate 30-50% more than the equivalent web-only build. The backend is shared, so the increment is the native client.
