MOBILE APP DEVELOPMENT

The mobile app development company that ships iOS and Android at a fixed price.

Qorinx is a mobile app development company in Tallinn, Estonia that builds iOS and Android apps for founders and growing businesses. Senior engineers ship one cross-platform codebase to the App Store and Google Play, with the backend, admin panel and store submission included. You get a fixed price and a delivery date in writing within 48 hours of a scoping call, a live demo from the first week, and all the code on handoff.

Mobile MVPs start at €15,000 and take 2 to 6 weeks. We build in Flutter, with Laravel or another backend behind it. The stack details are on our Flutter app development page.

iOS and Android from one codebase

One Flutter codebase compiled to native apps for both stores, so every user gets new features on the same day and you pay for one build, not two.

The backend behind the app

Accounts, the API, the database, push notifications and an admin panel your team runs the product from, usually on Laravel.

Payments and subscriptions

In-app purchases through the App Store and Google Play, or Stripe for services and marketplaces, wired up and tested before launch.

Native device features

Camera, location, push, offline mode, Apple Health, widgets and Live Activities when the product needs them. QoFast uses the last three.

Store submission handled

Developer accounts, signing, screenshots, privacy forms and review on both stores. If review pushes back, we fix it.

Yours on handoff

Source code, signing keys and infrastructure transferred to you with documentation. No lock-in and no license fee.

A typical mobile MVP

From first call to both app stores.

DAYS 1-2
Scope and quote

One call turns your idea into a written spec: the screens, the data and what launch means. The fixed price and date follow within 48 hours.

WEEK 1
First build on your phone

The main flow of your app runs as a live demo from the first week, so you see progress instead of status reports.

WEEKS 2-5
Features, payments, polish

The scoped features land with the backend, payments, push notifications and the edge cases that separate a demo from an app people keep.

WEEKS 4-6
Store launch and handoff

Submission to the App Store and Google Play, release, then the code, keys and infrastructure transferred to you.

Common questions

How much does it cost to build a mobile app?

With us, a mobile MVP starts at €15,000 and takes 2 to 6 weeks: one core flow, accounts, payments if you charge, and an admin panel, on iOS and Android. Apps with several user roles, real-time features or many integrations cost more. Either way you get one fixed price in writing after a scoping call, never an hourly bill. For what moves the number, read how much a Flutter app costs.

Can you build a mobile app MVP for my startup?

Yes, that is most of what we do. A mobile MVP from us is a real app in both stores with one core flow, accounts, payments and an admin panel, built in 2 to 6 weeks from €15,000. You see a live demo from the first week and own all the code at handoff. More on how we scope it on our MVP development page, or book a free 30-minute call to scope yours.

Do you build for iOS and Android at the same time?

Yes. We write one Flutter codebase and release it to the App Store and Google Play together, so both platforms get the same features on the same day and you pay for one build instead of two native ones. The backend, usually Laravel, serves both apps. Our Flutter app development page covers the stack in detail.

Which mobile apps have you built?

For clients: Circle Professionals, the employee app for the hospitality staffing agency Circle Hospitality, built in Flutter with a Laravel backend and live on iOS and Android. We also build and run our own apps, all live on the App Store and Google Play: SimFuse (travel eSIM, built in Flutter), QoFast (fasting tracker), TaleTuck (AI bedtime stories) and QoHush (baby monitor). See them all in our work.

Can I hire your mobile app developers for my team instead?

Yes. If you need ongoing capacity rather than one fixed-price build, our senior Flutter and backend engineers can join your team through our dedicated development team service. If you have a defined app to ship, a fixed-price project is usually faster and cheaper, and we will say which fits on the call.

Do I own the app and the code?

Yes. On handoff you get the source code, the signing keys, the infrastructure and the documentation. There is no license fee and no lock-in: any competent team can take the app over, and so can we if you want ongoing work.

How do I get started?

Book a free 30-minute call. We talk through the app, the users and what launch means, and within 48 hours you get the scope, a fixed price and a delivery date in writing. If an app is not the right first step, for example because a web app would prove the idea faster, we will say so on the call.
