Mobile App Development
iOS and Android, scoped together from day one, so neither platform is the afterthought.
From €3,600
Built for both platforms, not one plus an afterthought
The founder whose product is the app, not a website.
Mobile isn't a companion feature — it's the whole product.
The ops lead building a field-operations tool.
Your team needs a phone in their hand, often offline, often outdoors.
The team that got burned by a half-scoped mobile project before.
Half-built because nobody planned for both platforms, or for the store review process, at the start.
What the Blueprint plans before you build
- Platform decision (native vs. cross-platform)
- Feature scope document
- Store review readiness checklist
- Offline/data-sync plan
- A fixed price for the build
- Full native or cross-platform build
- Both app stores
- Push notifications & analytics wiring as scoped
- Staging builds via TestFlight/internal track
- Source handover
Not included
- App store fees (paid by the client directly)
- Ongoing OS updates beyond the fix window (available via the retainer)
From blueprint to store
- Mobile Product Blueprint (1 week) — Platform choice, scope, store-readiness plan.
- Build (platform-dependent, quoted after the blueprint) — Weekly TestFlight/internal builds you can test on a real device.
- Store submission — We handle the submission process and respond to review feedback.
- Launch & Growth retainer (optional) — Ongoing updates, OS compatibility, feature work.
