Lock your apps by default to improve your digital wellbeing
Every wellbeing app punishes you. Tomosu does the opposite. Instead of blocking apps, Tomosu restricts everything by default — notifications, badges, gone. Start a Focus Session to unlock only what you need. 🔒 All apps locked by default. Calm is the starting point. 🎯 Focus Sessions with presets (Work, Study, Creative) 🏋️ SNS Challenge — shake your phone before scrolling 💰 Focus earns coins. Longer SNS use = fewer coins. 🔐 Apple Screen Time API. Data stays on device. Free. No ads. No guilt.
Hey Product Hunt! 👋
I'm Ryoma, a solo developer from Japan.
I built Tomosu because every app blocker I tried felt like punishment — and I'd disable it within a week.
So I flipped the approach: what if your phone started QUIET by default? No notifications, no badges, nothing.
And when you actually need an app, you consciously choose to open it.
That one change transformed my relationship with my phone.
I stopped doom-scrolling — not because an app blocked me, but because I started asking "do I really need this?"
The SNS Challenge was born from a fun experiment: if you have to shake your phone 20 times before opening Instagram, you realize how many times you reach for it out of pure habit. 😄
I'd love to hear what you think — what would make this more useful for your daily life?
