Custom iOS, Android & web application development
From idea to a production-ready application.
We shape the product strategy, design, technical architecture and a working iOS, Android or web application. One team from the first idea through release and further growth.

Problem
Users need support at the exact moment a craving hits, and a clear view of progress without overwhelming statistics.
Product approach
A daily action-based quit experience combining preparation, guided interventions, progress and behaviour patterns.
Built by Aiprocesai
Product structure, UX/UI, the React Native application, authentication, subscriptions, analytics and the Google Play release.
Result
A real production product published on Google Play — not a demo or a concept design.
What you get
A complete product, not just code
Every project covers three full phases — from the first call to a live, maintained application.
Strategy & design
A product starts with clarity, not code.
- Discovery and scope mapping
- UX research and user journeys
- Wireframes
- UI design on your brand
- Interactive prototype before development
Development
One team — from screen to server.
- iOS + Android from one React Native codebase
- Backend, database and APIs
- Authentication and payments (Stripe)
- Push notifications and analytics
- Admin dashboard for content
Launch & maintenance
A live app — not a handed-over archive.
- App Store and Google Play publishing
- Testing on real devices
- Team training and documentation
- 100% code transfer
- Support plan from €149/mo
Process
Seven steps, one accountable partner
Technology
Technology chosen for the product
Every technology here reduces your cost or your risk — one maintainable codebase, faster release cycles, secure authentication and reliable subscription management.
Why us
How we differ from a large agency
You talk to the people building your product — no project-manager relay.
Weekly demos. We adjust course during the build, not after three months.
React Native, TypeScript, Supabase — easy to maintain and extend.
Design, code and publishing are all done in-house.
Speed and stability are a feature, not an afterthought.
Fixed price against a spec. Extra scope is quoted upfront, separately.
We ask how the app earns — not just which screens it needs.
Structure and documentation any team can take over.
Pricing
Transparent pricing — starting from €2,399
The final price is confirmed after assessing functionality, integrations, design complexity and release scope — and fixed before development starts.
Launch MVP
For validating one clearly scoped product idea with real users.
A focused first release, live on Google Play.
- 5–7 core screens, one user type
- React Native app, basic authentication
- Google Play preparation (or agreed release)
- One structured revision stage
See typical scope
- Discovery workshop and documented scope
- UI design on your brand
- Basic backend (Supabase)
- Basic analytics
- Code handover
Deliberately excluded: complex integrations, multiple user types, real-time features.
Business App
For businesses whose app serves customers or staff every day.
A complete product with payments, admin and launch.
- 10–18 screens, multiple user flows
- Payments / subscriptions and push notifications
- Admin dashboard
- QA and launch support
See typical scope
- Detailed product architecture
- Authentication and user management
- Analytics and error monitoring
- Selected third-party integrations
- iOS and Android preparation
Excluded: AI features and multi-role platforms — that is Advanced scope.
Advanced Platform
For products with multiple roles, AI features or complex logic.
A scalable platform with monitoring and technical handover.
- Multiple user roles and complex logic
- AI features (assistants, recognition, recommendations)
- Complex ERP / CRM / API integrations
- Automated tests where they pay off
See typical scope
- Advanced application architecture
- Custom administration platform
- Subscription and billing systems
- Monitoring and analytics
- Launch planning and technical handover
Final scope and price are confirmed after the specification.
Payment terms
A 50% deposit is paid before work begins. The remaining 50% is paid after the agreed scope is completed and before final production deployment or handover.
Additional scope
Changes beyond the spec are estimated and approved before implementation — the original budget never drifts.
Not included
Hosting, Apple ($99/yr) and Google ($25) fees, and usage-based third-party APIs — unless agreed otherwise. Source code transfers after full payment.
Questions
Frequently asked questions
How much does it cost to build an app?
A Launch MVP starts at €2,399 (a limited first-version scope: 5–7 screens, one user type), a business app with auth, payments and an admin panel from €5,900, and a complex platform from €11,900. The final price is fixed against a written spec before development starts — no surprises mid-project.
How long does development take?
MVP: 4–6 weeks. Business app: 8–12 weeks. Advanced platform: 12–20+ weeks. The timeline is fixed together with the price at the spec stage. For comparison, traditional agencies quote 3–6 months for similar scope.
Will the app run on both iPhone and Android?
Yes. We build with React Native — one codebase runs on both platforms. That is up to 60% cheaper than two separate native apps, and every update ships to both stores at once.
Do you publish to the App Store and Google Play?
Yes, publishing is included: store listings, screenshots, privacy policy and the full Apple and Google review process until the app is live. We have been through that path with our own product, VapeReset.
Who owns the source code?
You do. 100% of the code and IP transfers to you after final payment. Any team can take the app over later — no lock-in.
Can you improve or redesign an existing app?
Yes. We audit the existing app (code, design, performance), present a plan, and either improve the current base or — when cheaper long-term — rebuild it on a modern stack while preserving features and users.
Do you provide the backend?
Yes — full scope: database (Supabase / PostgreSQL), authentication, APIs, admin panel, payments (Stripe), push notifications and analytics. The app ships working end to end.
Can AI be integrated into the app?
Yes — it is our strength: AI assistants, text and image recognition, personalised recommendations, natural-language search. AI is designed into the architecture from day one, not bolted on at the end.
Do you maintain applications after launch?
Yes — a support plan from €149/month: OS compatibility updates, bug fixes, small improvements and store policy changes. A clean handover with no monthly fee is also possible.
What technologies do you use and why?
React Native + Expo (one codebase for iOS and Android), TypeScript (fewer production bugs), Supabase / PostgreSQL (reliable backend without excess infrastructure), Stripe (payments), Firebase (push), OpenAI / Claude (AI features). Chosen for the project, not for fashion.
