What a mobile app costs to build — and to keep running
App quotes usually cover the app. The budget that actually matters also covers the backend it talks to, the store lifecycle, and the OS updates that arrive every autumn whether you planned for them or not.
Outcomes
- A realistic total, not just the build
- Clear platform trade-off in money terms
- Maintenance budgeted before launch
- An indicative estimate in minutes
Pricing
Where it is used
Single-platform business app
Forms, sync and one integration — €35,000 to €70,000.
Cross-platform customer app
Accounts, payments, notifications — €60,000 to €140,000.
Field operations suite
Offline, hardware, dispatch and backend — €120,000 upwards.
What we deliver
- Platforms: two native apps instead of one adds 40 to 70 percent
- Offline behaviour: sync and conflict resolution is real engineering
- Hardware: scanning, BLE and background location add integration cost
- Backend: often half of a mobile budget
- Store lifecycle: submission, review and OS updates every year
Who this is for
- Companies costing a field, warehouse or customer-facing app.
- Teams deciding between cross-platform and two native applications.
How delivery runs
- 01
Scoping
One to two weeks on the real workflow, systems and data. Output is a written scope and an indicative band.
- 02
Phased plan
The first usable release is identified explicitly so spend produces something usable early.
- 03
Fixed first phase
Phase one is quoted as a fixed price where scope allows; later phases are re-estimated with real velocity data.
- 04
Change log
Anything added after sign-off is estimated and scheduled in writing, so the budget never moves quietly.
Realistic timeline
Weeks 1–2
Platform decision, offline strategy and scope.
Weeks 3–10
Core app with backend, tested on real devices.
Weeks 11–14
Store submission, pilot rollout and fixes.
Build or buy
Buy something existing when
- A responsive web application is often enough when there is no offline or device requirement
Build custom when
- Offline, scanning, push or app-store distribution are genuine requirements
What moves the price
Native versus cross-platform
One cross-platform codebase usually lands well below two native builds; heavy device or performance requirements reverse that.
Offline behaviour
Working offline with conflict resolution is one of the most expensive requirements in mobile and must be decided early.
Device features
Camera, scanning, location, Bluetooth peripherals and push notifications each add build and test scope.
Store and release overhead
Store accounts, review cycles, signing and staged release are ongoing costs, not a one-off.
Where projects go wrong
Budget set before scope
A number agreed before discovery is a guess. We give a band after a short scoping phase and narrow it once the workflow and integrations are documented.
Data migration priced last
Legacy data is rarely as clean as expected. We survey the actual export during discovery rather than assuming it at the end.
FAQ
Questions buyers ask
Is cross-platform cheaper?+
For form-driven business apps, usually yes — one codebase, one QA cycle. Heavy device use can erase the saving.
What does maintenance cost?+
Budget 15 to 20 percent of build cost annually just to stay current with OS and store requirements.
