Apps people actually use,
every single day.
SmartDaisso is a mobile app studio that designs, builds and ships Android · Flutter apps end to end. An alarm that gets you out of bed, a vocabulary book built with your camera, the sounds you fall asleep to — we make the apps that get opened once a day.
Our apps
Tap a card to open it on Google PlayAn alarm that only stops once you clear a mini-game mission. No more switching it off and drifting back to sleep.
Point your camera at a word and it lands in your own vocabulary book. Recognition runs entirely on the device.
Fall asleep to white noise and wake up to a sleep report. Snoring and sleep talk are labelled on your phone, not in the cloud.

Saju (Korean four-pillars) readings, face reading, compatibility and today's fortune in one place.
Checks a QR code or link for phishing before you open it — against the unsafe-site list Google maintains in real time, plus lookalike-domain detection on the device. Reads only, never opens on its own, and says "unverified" instead of guessing "safe".
A journaling app that prints your day's feelings, choices and spending as a single receipt.
Gets you through the 90 seconds when anger flares, then helps you look back once it has passed.

30 step-by-step science experiments kids can do at home. A guardian confirms every risky step, and it all works offline.
How we build
Rules the whole studio follows — not decided app by app01 On the device, no servers
Word recognition, cry analysis and sleep labelling all happen on the phone. Data that never leaves can't leak.
02 Personal data kept to a minimum
Your records stay on the device and are excluded from cloud auto-backup. No account needed — just open the app.
03 Free with ads, no purchases
No in-app purchases. Every feature stays open; only the parts that cost us money are extended by watching an ad.
04 Real devices before release
Every release build is installed on a real phone and checked before it is sent to the store.
