Nothing is blocked. You trade for it. Atmo puts one card in front of the apps you open without thinking. Thirty seconds to read it, one question to answer, and the app opens for five minutes. No wall, no lecture, no guilt. HOW IT WORKS 1 — Choose the apps that eat your evenings. They pause. 2 — Tap one. Atmo shows a card: one fact, one question. 3 — Answer it. The app opens. You keep the minutes, and you keep the fact. EIGHT SUBJECTS, THIRTY SECONDS AT A TIME Arts · Economy · Geography · History · Mythology · Philosophy · Sciences · Space Each card is one idea and one question. Not a course, not a game. Something true you did not know this morning, learned in the thirty seconds you were about to give to a feed. A TRADE, NOT A WALL Blockers say no, and you delete them by Thursday. Atmo asks a question instead. You always get through — you just leave with something. There is no willpower to run out of here, and nothing to feel bad about. Set your own rhythm: how many cards a day, how many minutes a card is worth. Change it whenever you like. Stop whenever you like. WHAT YOU GET BACK · Minutes traded, day by day · Progress subject by subject · A card you miss comes back in a couple of days. Nothing is lost. PRIVATE BY DESIGN Atmo uses Apple Screen Time to pause the apps you pick. It only ever learns their names. It cannot see what you do inside them, and nothing about your usage leaves this phone. FREE AND PREMIUM Free: the trade, your apps, your rhythm. Premium: every subject, no cap on cards a day, your own rate. Five minutes at a time, you scroll the same and know more. Or you scroll less. Most people do both. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.quiet.app/privacy-policy
