Mobile app development for iOS and Android
Apps people keep on their home screen, from the first store release to years of OS updates.

What we build
Mobile apps we design, build and publish
We do not only build apps for clients, we publish and run our own: Sera, a private cycle tracker on iOS and Android trusted by thousands of users, an app that records from DJI wireless microphones over Bluetooth, and games on Google Play. So we know the whole road, from choosing between native and cross-platform to store review, privacy rules and keeping an app working through every new version of iOS and Android.
-
01
Consumer apps for iOS and Android
Polished public apps built for ratings, retention and reviews, published under your own developer accounts.
-
02
Internal apps for teams in the field
Tools for technicians, sales and service staff that are quick to use on the move, even with a weak signal.
-
03
Apps for Bluetooth and connected devices
Pairing, streaming and control of hardware over Bluetooth, the same kind of work as our DJI Mic Recorder app.
-
04
Privacy-first apps for sensitive data
Health and personal data kept on the device where possible, encrypted where it travels and never shared by default.
-
05
Backends for mobile apps
Accounts, sync, push notifications, analytics and admin tools, built together with the app so both sides fit.
-
06
Mobile games and interactive apps
Arcade and casual games with smooth performance and store-ready polish, like the ones we publish on Google Play.
Typical problems we solve
Decisions and problems we help with
-
Native, cross-platform or both?
We weigh your features, the device access you need, budget and future team, then recommend Kotlin and Swift, a shared codebase or a mix, and explain what each choice costs later.
-
The app works in the office but fails in the field.
We design offline-first: data is saved on the phone, synced when the connection returns and conflicts are resolved by clear rules instead of lost edits.
-
Store review keeps rejecting releases.
We know the App Store and Google Play guidelines from publishing our own apps, and prepare permissions, privacy declarations and review notes before the build goes out.
-
Every OS update breaks something.
We test on current and upcoming iOS and Android versions, keep dependencies current and track crashes, so updates are routine instead of emergencies.
Own products
We ship and run our own software, too.
Products we design, build and operate ourselves, used by real people every day. Your project gets the same care.
-
Cycle and intimacy tracker
Sera
A private cycle and intimacy tracker built for women who value privacy. Deployed on iOS and Android and trusted by thousands of users.
-
Bluetooth audio recorder
DJI Mic Recorder
Records from DJI wireless microphones over Bluetooth, straight on your phone, and keeps you in control of your sound.
Independent app, not affiliated with DJI.
-
Arcade, casual and story games
Our games
Pigeon Payback, Piggy Whack and MyTale: small worlds we build for fun, published on Steam, Google Play and the App Store.
How we work
From idea to the app stores, and beyond
-
01
Product and platform decisions
We define the core user journeys and choose native, cross-platform or a mix based on what the app has to do.
-
02
Design and prototype on real phones
Clickable screens and an early build on your own device show how the app feels before full development starts.
-
03
Build, test and release
Short iterations with test builds for your team, then store listings, review and a staged rollout to users.
-
04
Keep it current
New OS versions, new devices, store policy changes and user feedback: we stay on to keep the app healthy and growing.
How every engagement runs
-
Clear scope and estimate
You know what you get, when, and what it costs before work starts.
-
Working software early
Short iterations with results you can see and test.
-
Transparent communication
Direct contact with the engineers, regular updates and no surprises.
-
Support after release
We stay responsible for what we delivered.
Questions and answers
Frequently asked questions
-
Should we build native apps or one cross-platform app?
Native Kotlin and Swift give the best performance and full access to device features such as Bluetooth, sensors and background work. A shared cross-platform codebase can lower the cost when the app is mostly screens, forms and data. We recommend based on your features, not on habit.
-
Do you publish the app to the App Store and Google Play?
Yes. We prepare the store listings, privacy declarations and review notes and submit the app under your developer accounts, so the app, its ratings and its users belong to you. We go through the same review process with our own apps.
-
Can the app work offline and talk to Bluetooth devices?
Yes. We design local storage and sync for unreliable connections, and we have built Bluetooth communication with hardware in our DJI Mic Recorder app, which records audio from DJI wireless microphones.
-
What affects the cost of a mobile app?
Mainly the number of screens and user roles, whether you need both platforms at once, offline sync, device integrations and the backend with its admin tools. A focused first version is often the best start: it reaches users sooner and real feedback shapes what comes next.
-
What happens after the app is launched?
Apps need regular care: updates for new iOS and Android versions, store policy changes, crash fixes and new features. We offer ongoing maintenance, and you always keep the code and the store accounts.
