Try flutter, ai, pricing or sudoku

Practice 02

Apps that survive the store, the updates, and the truth — one Flutter codebase where it wins, native where it pays.

We take products from architecture to Google Play and keep them healthy afterwards. The team maintains its own published apps — Sudoku Master, Money AI and Invoice Maker — on the same pipeline we use for clients.

Scope mobile app development →Typical product build: 8–16 weeks discovery → launch.

What’s in the box

  • 01Discovery & fixed-scope brief
  • 02UX flows with every state designed
  • 03React Native or Flutter builds
  • 04Native Android (Kotlin) where it pays
  • 05Firebase or Node backends, typed contracts
  • 06Store launch, rollout & monitoring
  • 07Post-launch support window

Deliverables at handover

  • Signed scope document with milestones
  • Design files (Figma) + component specs
  • Source in your repo, your store accounts
  • Release & rollback runbook
  • Support window with monitoring notes

Questions this practice gets

How do you price projects?
Fixed scope against a signed brief, split into milestone payments. After discovery you get a number, not a range. If scope changes later, it is priced in writing before work starts — the change rate is agreed in the same document so nobody negotiates under deadline.
Who owns the code, accounts and store listings?
You do, from day one. Repositories, cloud projects and store accounts are created under your organisation; we collaborate inside them. That includes design files, documentation and any admin tooling we build for you.
Which mobile stack will my app use?
Our default is React Native or Flutter for product coverage at realistic budgets; native Kotlin when performance or deep OS integration justifies it. We maintain production apps in this family ourselves, so recommendations come with maintenance numbers, not vendor slides.

Let's build the mobile app development the right way.

One paragraph is enough to start — we reply within a working day with questions, a direction, and whether we're the right studio for it.
