Hey Product Hunt! π
I'm Ryoma, a solo developer from Japan.
I built Tomosu because every app blocker I tried felt like punishment β 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 β 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. π
I'd love to hear what you think β what would make this more useful for your daily life?
