Software that respects your time and your data.

Small, calm apps for Mac, iPhone and iPad. No accounts to create, no servers holding your life, no AI deciding things on your behalf. You open them when you need them, and they get out of the way.

Made in Germany · English & Deutsch

What that means in practice

Your data stays yours: Apps work on the accounts you already have. No moosystems server, no sign-up, no tracking.
Nothing shouts at you: No badges, no banners, no pings. An app should wait until you come to it.
No AI doing your thinking: A considered removal, not a missing feature. Fast tools that leave the judgement to you.
Buy it once: One purchase, not a subscription — and it covers every device you own.

Make My Day

Make My Day on iPhone: the day's outcome written at the top, four goals in their colours, and the morning on one timeline — a stand-up followed by two tasks carrying the colour of the goal they serve.
