Mobile app development

Apps for Android and iOS — for example when your team works on the road or on site, sometimes without internet. We first check whether you really need a native app, or whether an installable web app does the job more simply.

When to come to me with this

  • Colleagues report where they were and what they did on paper or by message.
  • Work happens where there is no signal, and data must not get lost.
  • The phone's camera, location or notifications are part of the job.
  • You have a web system and need a simple app for its field side.

What it includes

  • the decision: native, Flutter, or an installable web app (PWA)
  • offline use: collects without signal, catches up when back online
  • the web admin and backend that go with it
  • release to Google Play and the App Store, or company-only install

How it works

The first step is walking through a typical working day: what the colleague does with the phone, and what the office needs to see from it. That tells us which kind of app is needed. My own products run on Android and the web; in client work over the past eight years I have also built for iOS and with Flutter, Xamarin and Kotlin.

Examples from my work

  • KlipA native Android app: the phone detects arrival and departure from the site radius on its own, even without signal. Live on 148 sites and 19 phones.Case study →
  • Clair ContourAn AR view on Android and iOS: the phone camera shows how an artwork would look on your own wall, at its real size.Case study →
  • CasitaAn installable web app (PWA) that works the same on phone and desktop.

Price

For larger projects I give a fixed price split into milestones. Day rate: HUF 100–120k, hourly: HUF 17,500. The first hour is free: we talk through what you need.

Questions

Do I need a native app, or is a web app enough?

If it has to track location in the background, work reliably offline or use phone sensors, you need a native app. If it is mostly forms and lists, an installable web app is cheaper and needs no store release.

Thinking of something similar?

Write a few lines about what you want to solve, and we will work out the best next step. The first hour is free.
