Web and mobile products
We design, build and launch web apps and iPhone and Android apps, from the first wireframe to release on the App Store and Google Play, with AI where it helps.
The first call is free and takes 30 minutes. We reply within one working day.
- Engagement
- Product build, six to twelve weeks
- Launch
- App Store, Google Play or the web
- Price
- Fixed, agreed in writing before the build
- Ownership
- You own all code and accounts
What it is
Full product engineering: design, front end, back end, sign-in, payments, analytics and the store release. We act as your product team for the build, then hand over clean, documented code, or stay on to keep improving it. Design and code are done by the same team, so nothing is lost between the mock-up and the build.
Who it is for
- Founders going from idea to a first version who want it built properly from day one
- Early-stage teams replacing a rushed first version with the real product
- Companies adding a mobile app alongside an existing web product
- Teams whose automation needs a front end for customers or staff
What the build includes
Web apps
React, Next.js, TanStack Start and TypeScript, with server rendering where it matters for speed and search.
Mobile apps
iPhone and Android apps in Swift and SwiftUI, Kotlin, or React Native when it fits, with the App Store and Google Play launch included.
Back end and APIs
Supabase, PostgreSQL, edge functions, REST and tRPC APIs, queues and scheduled jobs.
Sign-in, payments and infrastructure
Stripe, OAuth, role-based access, multi-tenant setups, file storage, email, analytics and error monitoring.
Design
We design in-house, so the same team owns the screens and the code.
How we build it
A fixed price is agreed in writing before the build starts, and you get a working version to try every Friday.
- Step 1Scope the first version in a short discovery phase
- Step 2Design and prototype while the engineering setup is built
- Step 3Build in weekly milestones, with a live preview from the first week
- Step 4Test for quality, speed and accessibility, then submit to the stores
- Step 5Stay on after launch to keep improving it, if you want us to
What you get
- A live product on the web, the App Store or Google Play
- A documented codebase your next developers can work in
- Design and code from the same team
- All code and accounts in your name
Built with

Design, engineering and launch: the screens, the front end and back end, sign-in, payments, analytics and the release to the App Store, Google Play or the web. You get weekly releases along the way and own all the code and accounts.
A product build usually takes six to twelve weeks, with a working version to try every Friday. The timeline and one fixed price are agreed in writing before the build starts.
Yes. TOGA, Bandwise, Forge and Pledge are live on the App Store and Google Play, and Quran is live on Google Play. We designed, built and launched each one ourselves, and every client product goes through the same process.
Yes. Most of our own apps have AI at the core: TOGA logs meals from a photo, Bandwise marks spoken and written answers, and Forge and Pledge each include an AI coach.
