How we work

A clear path from idea to launch. From the second step you can try your app on your own phone.

  1. A call, then a plan

    We call you to talk through what you need and who will use it, then send a written plan and a quote for the first release.

  2. Design

    You tap through the main screens on your own phone before we write the code.

  3. Build

    You get test builds as we go, so you can try the real thing and steer it.

  4. Launch and care

    We publish to the App Store, Google Play or the web, then keep it running and improving.

Why work with us

We build and run software of our own, so we know what it takes to launch and keep it working.

in Accra right now. Ghana keeps GMT all year, with no daylight saving, so in the northern winter 3pm here is 3pm in London.
