Mobile apps for iOS and Android — from idea to the stores

We build apps with React Native: one codebase, both platforms, released to the App Store and Google Play. The first working version ships after 4–6 weeks of development; from there we grow the product on real user data.

What we build

Typical projects

Consumer apps

Onboarding, push notifications, content tailored to each user. That's how Wispy and MemoAI work — AI assembles lessons and programs per person.

Two-sided services

Marketplaces and aggregators with a buyer and a provider side: moderation, payments, notifications. Example: YNA, an events app for Dubai.

Tools for field teams

Apps for staff on the move: offline mode, sync, QR check-ins. WMS replaced manual cleaning logs with two apps and an admin panel.

Apps for hardware

Bluetooth links to hardware and native modules where React Native falls short. For BrainPatch we built a stable link between the neuro-headset and the app.

Discovery

We unpack the task, goals and constraints. We scope the first release.

021–2 weeks

Design

Prototype and key screens. We align on the logic before any code.

034–6 weeks

Build & demos

Demos every 2–4 weeks plus access to in-progress builds — you can track progress anytime.

Launch & support

Release, monitoring, on-call. We keep the system alive.

FAQ

Frequently asked

How long does it take to build an app?

The first working version usually takes 4–6 weeks of development, after 3–5 days of discovery and 1–2 weeks of prototyping the key screens. Larger products take 2–3 months: YNA shipped in 2, a month ahead of contract; Dosym took about 3.

Why React Native rather than native?

One codebase for iOS and Android: features ship to both platforms at once and maintenance costs less. Where native is needed — say, a Bluetooth link to a device — we write native modules. That's how the BrainPatch headset talks to its app.

Do you handle the App Store and Google Play release?

Yes, store release is part of the job. Wispy, Dosym and BrainPatch are among the apps we've published.

What happens after launch?

We don't disappear after release: monitoring, on-call and growing the product on data from real users.

How much does it cost?

It depends on scope, so we estimate per project: you get an estimate within a day or two of the brief. Scope, price and timeline are fixed in writing before we start, and payments are staged. Fixed price or time & materials.
