Four products, one idea: software that respects your time and your privacy. Everything we build works offline first, keeps your data on your own device, and speaks Arabic, English, and German from day one.
One app for the parts of life that usually live in five different places. Appointments with reminders that actually fire, tasks sorted by priority, a daily notebook, expenses with charts, medication schedules, shopping lists, contracts and documents, and a secure vault locked behind your fingerprint. Everything is stored on your phone — no account, no cloud, no tracking — and backups can be encrypted before they ever leave the device.
Available on Google Play
A logic puzzle where the hidden squares spell a word. Open a square and its number tells you how many hidden letters touch it — from the numbers alone you can find every letter, and no board ever needs a guess. Clear the board and the word appears, with a fact worth knowing. A hundred stages in four levels, a daily challenge shared by every player, seasonal events, and progress that follows you through iCloud — no ads, no purchases, no account.
Available on the App Store
A code-breaking puzzle game. Each stage is a vault: enter a code, and the game tells you how many digits are right and how many sit in the wrong place. From there it is pure deduction. Ninety stages across four difficulty levels, with harder elite vaults every few rounds, a daily challenge, and a code that is generated uniquely on every device — so the player next to you cannot simply read the answer off your screen.
Available on Google Play and the App StoreMaths, physics, and chemistry in one place, built for the moment you are stuck on a problem. Clear explanations instead of walls of text, plus the tools you actually reach for: calculators, unit and formula converters, constants, and worked examples. Designed for students and for anyone who left school long ago and wants the subject to finally make sense.
In DevelopmentLife Manager and CodeLock are live on Google Play and the App Store, and Z-Sweep is on the App Store, with Google Play to follow. Science Atlas is still in active development — we would rather ship something small that works than something large that almost does, so features arrive when they are genuinely ready.
