Colouring · for adults
Zenful — cosy colouring
Beautiful colouring books that spark imagination and soothe the mind. For unwinding after a loud day, or a quiet meditative habit that actually sticks.
A small app studio · est. Europe
Apps for people who choose creation over distraction.
We're four humans across three European countries making calm, crafted apps — for colouring, writing, remembering, and switching off the noise. Nothing that pings you. Everything made to keep.
Four apps, one belief.
Screens should leave you better than they found you. Here's what that looks like in practice.
Colouring · for little hands
Zenful Kids — big imaginations
Playful pages and friendly tools that turn screen time into creative time. No ads, no rabbit holes — just a happy pencil and room to make things.
Handwriting · for young writers
Rito Kids — handwriting is child's play
Meet Rito the penguin. Letter by letter, he turns handwriting practice into an icy adventure — built with 10+ educators, with instant, teacher-informed feedback on every stroke.
Memoir · guided journal
Thymo — your life, in a book
Turn memories into a beautiful biography without typing a word. Thymo asks, listens, transcribes and edits — until your story is a book your family will keep.
Made with intention, not metrics.
Technology should enable creativity, balance and inner calm — not overwhelm, or pull people away from what matters. That belief shapes every decision we ship.
Calm by design
No streaks, no guilt trips, no engagement traps. Our apps wait patiently for you — features have to earn their place on the screen.
Craft over scale
A four-person team across three countries, drawing and polishing every corner ourselves. Small releases, big attention to detail.
Made to keep
Pages you colour, stories you tell — they're yours. We build things worth returning to, and worth passing on.
Four humans, three countries.
One shared belief, four very different desks.

Building an app? We can help.
The same four hands that make our apps can work on yours. We take on a few outside projects a year — and keep them small enough to care about.
