Mobile apps
iOS and Android from a single Flutter codebase, or natively in Swift and Kotlin. Notifications, offline mode, widgets, watch integration, in-app purchases, and release to the App Store and Google Play.

We build apps to order
and grow our own.
MajaTech designs and builds mobile and web applications — from the first sketch, through store releases, to long-term development. We run our own products in parallel, so we know every stage: not only the code, but also publishing, payments, analytics and maintenance.
What we do
The full scope of work on an application — from an idea to a version maintained in production.
Web apps
Dashboards, internal tools and product sites. Fast, accessible and lightweight — without the extra layers that become hard to maintain later.
Backend and cloud
APIs, databases, authentication, sync and subscriptions. We work with Supabase, Firebase and Cloudflare among others — the solution is picked to fit the project, not the other way round.
Rescuing legacy projects
We take over code written by other teams: audit, bug fixing, dependency and toolchain upgrades, and — when it is the right call — a controlled rewrite onto a modern stack.
Data and on-device machine learning
Image processing, sensor signal analysis and models that run locally on the phone. No sending private user data to a server unless it is genuinely required.
Support and maintenance
An app does not end at launch. We handle further releases, monitoring, store requirements and platform changes.
How we work
Conversation and scope
We agree what is being built and why. You get a clear scope and a time and cost estimate — before a line of code is written.
Short iterations
We work in small steps with working builds to review. You see progress as it happens and can reshuffle priorities.
Release and handover
Publishing, documentation and access to the code. The project is yours — we can keep developing it or hand it to your team.
Our products
Applications we build and maintain ourselves. They are where we test the solutions we later bring into client projects.
grow
in developmentA task manager that, instead of a long list, shows you one next task — matched to the time of day, deadlines and what you have already postponed. Works fully offline, with optional cloud sync.
Target Practice
in developmentA shooting training companion: target scoring from a photo, a shot and session log, and dry-fire drills with voice cues. Optional hold-stability analysis from watch sensors.
My Expenses
archivedThe quickest way to log an expense on iOS — no heavy reporting, but smart category suggestions instead. At its peak it reached high positions in the App Store finance rankings.
RunTrainer
being rewrittenA running training app with intervals and pace tracking. The legacy Objective-C code was fixed and rewritten in SwiftUI and Kotlin, together with Apple Watch and Wear OS versions.
duplicates
open sourceA command-line tool for taming photo collections: it finds duplicates by content hash and decides which copy to keep, based on configurable path rules.
