Cross-platform iOS & Android apps
React Native applications that feel native on both platforms while sharing business logic and a single release pipeline.
Mobile App Development
Mobile app development — apps your customers actually keep installed
Put your product in your customers' pockets.
We build iOS and Android applications for established companies — connected to the systems you already run, shipped to both stores, and maintained past version one.
- Fixed scope & price
- Agreed before any code is written
- You own everything
- Code, infrastructure, and documentation
- Europe & MENA
- Overlapping hours, async written updates
The problem
Most company apps die after version one
An agency built the app, invoiced, and left. Two OS releases later it crashes on modern devices, the store listing is stale, and nobody internally can build it, let alone ship an update.
- The app has not been updated in over a year
- Nobody on your team can produce a release build
- It duplicates business logic your backend already owns
- Reviews mention crashes you cannot reproduce
- Store listings are neglected and installs have flatlined
What we build
What we actually build
One codebase for both platforms in most cases, connected to your real systems rather than a demo backend, with the release process documented and handed over.
Customer-facing product apps
Accounts, payments, notifications, and offline-tolerant flows for products your customers use regularly.
Internal & field-team apps
Tools for staff who work away from a desk — inspections, deliveries, stock, and approvals that sync when connectivity returns.
Store launch & release process
App Store and Play Console setup, review submission, and a documented pipeline your team can run without us.
Capabilities
What is included as standard
- Native-quality UI on iOS and Android
- Offline-first data and conflict handling
- Push notifications and deep linking
- In-app purchases and subscription billing
- Biometric and SSO authentication
- Over-the-air updates without store review
- Crash reporting and release monitoring
- App Store and Play Store submission
When companies call us
Typical situations we are brought into
Your customers expect an app
Repeat-use products — booking, ordering, accounts, loyalty — where mobile web friction is measurably costing you retention.
Your field team works on paper
Staff outside the office capturing data on paper or WhatsApp, which someone later re-enters into a system by hand.
An existing app needs rescuing
You inherited an app that still has users but no working build process and no one willing to maintain it.
You need a credible MVP
You want a focused first version in front of real users to validate demand before committing to a larger roadmap.

Process
How the engagement runs
- 01
Discovery & scope
We map your current systems, constraints, and commercial goals, then agree what is in scope — and what deliberately is not.
- 02
Architecture & plan
You get a technical approach, milestone plan, and fixed commercial terms before any code is written.
- 03
Build in increments
Two-week increments with working software at the end of each. You review real builds, not status decks.
- 04
Launch & handover
Testing, migration, and documented handover so your team can operate the system without depending on us.
- 05
Ongoing partnership
Support, iteration, and a named engineer who already knows your stack when the next thing comes up.

Questions
What buyers usually ask
A focused first version typically runs €35,000–€80,000 across both platforms. Larger products with complex offline behaviour, payments, or deep back-office integration go beyond that. You get a fixed scope and price after discovery.
Clients
What working with us is like
We were losing patients at the booking stage and could not work out why. The front desk answered what it could and everything else went to voicemail at exactly the hour people call. Leet Force did not start by building anything, they spent the first week in our phone logs. Booking abandonment fell 65% once patients could see real availability and book without waiting for anyone. Eighteen months on they still maintain it, and I have never once had to chase them for an update.

The part I did not expect was how much calmer the mornings became.

Opening an account took eleven minutes and most people gave up. Two agencies had already told us it was a design problem. It was not, it was four systems that refused to talk to each other, and Leet Force were the first people to actually say so. They rebuilt the flow around that and onboarding came out two and a half times faster. They also talked us out of two features we were certain we needed, which saved us more than the project cost. I have worked with a lot of agencies and almost none of them will argue with you.

What usually comes with this
Not sure an app is the right call?
We would rather talk you out of a bad app than build one. Bring the use case and we will tell you whether mobile, web, or messaging fits it better.
