Build magic

Small software for the quiet parts of the day.

OZJAM is an independent studio. We make a small number of apps and games, and let each one take the shape its own problem needs. What they have in common is not speed; it is that someone thought about them.

How we work

A small number of apps, made without hurry.

Each app has its own problem and its own constraints. What they share is not a feature list; it is how the work gets done.

We ask for as little as the job needs

An app should ask for whatever data it genuinely needs, and nothing beyond that. Warry asks you for none, because it does not need any.

Each app takes its own shape

Warry works offline because a home inventory has no need of a server. If another problem needs a different structure, we will say so rather than pretend.

Nothing to learn

Screens that explain themselves, the same on iPhone and Android. You start using them in the first minute, no manual required.

A human, not a bot

The person who writes the app answers your e-mail. There is no support desk in between.

Products

Out of the studio

Both are on the App Store and Google Play. Both small, both thought about for a long time.

Our approach

Four steps, taken slowly.

None of this is fast. It is also the part that decides whether an app is worth keeping on your phone.

Get in touch

  1. Pick a real problem

    We start from something we run into ourselves — a need whose current solution is still clumsy.

  2. Strip out everything else

    The first release is the smallest thing that solves the problem. The outcome matters, not the feature list.

  3. Build with the least data possible

    If a feature can work without asking for data, that is how it gets built. In Warry that came out as no account and no server: what you type stays on the phone.

  4. Listen, then refine

    Every piece of feedback gets read. The good ideas make it into the next version.
