How we work
You see it working before it launches.
01🎨Design
We start from whatever you can give us — images, text, even hand-drawn diagrams — and turn it into static designs of every screen. You review them, leave notes, and we iterate until you sign off. Then we deliver the apps and the code, with the approved designs in place.
02🎬Build
We build the app out and send you videos of each part working. If a screen depends on data, you get a video of it with each kind of content. These images and videos are created programmatically, so they are regenerated on every single build. When you sign off, we deliver the apps, the videos and the code.
- 03🧪
Beta
We open a beta and iterate on real usage data and feedback. Every build reports its changes against those same images and videos, so you sign off on exactly what changed — no surprises. We recommend staying in beta, with the app free, until the statistics show users signing in, staying and coming back.
- 04🚀
Launch
When retention holds, we launch — and keep iterating on the data and feedback. Development is billed up to the beta; from there it switches to the Care Plan, a flat 10% of the monthly development fee.
The apps and full source code are delivered at every stage — and you can cancel at any time and keep them.
Proof
Apps people come back to
Real products. Real users. The kind of growth that earns a proper launch.
Sionnach
Language-learning app
Launched to answer one question: would people come back? Over 15,000 users arrived in under a year — and they stayed. That is what earned the full release.
Madra Teanga
Community language platform
Everything the beta proved, released properly. Learners use it on iPhone, Android and the web — and the community creates the courses themselves.

After the beta
The Care Plan
From the beta until handover · cancel any time
e.g. development at €10,000/month → €1,000/month
It covers everything from hosting to changes. New features, major work, and hosting data beyond normal app use — massive video, say — are quoted separately.
Think of it as a CTO and developer for hire. Cancel at any time and everything is handed over — the apps, the source code, the accounts and the data. We keep nothing.
