A time tracker that splits your day into 15-minute blocks. That's the whole idea. 96 blocks a day, from when you wake up to when you go to sleep. You write down what you did in each one. Nothing more complicated than that. We promise it will change the way you work, the way you doomscroll, and the way you function. Not because it nags you, but because for the first time you'll see, in plain numbers, exactly where your time goes. This is a new way to be productive. You don't plan your day. You track it, fifteen minutes at a time. (4x 15 minute blocks make an hour. A day equals 96 blocks.) HOW IT WORKS 1. Open the app, no account, no sign-up. 2. Tap any 15-minute block and type what you just did, like "deep work," "lunch," or "doomscrolling." 3. Give the block a category, like Work, Gym, or Sleep, so you can see where your time goes. 4. Did one thing for hours? Fill the whole stretch with a single category in one step. 5. Open Stats and watch your real day show up in color. Five minutes of tracking a day. That's the entire commitment.
