Mosslock locks the apps that pull you away while you study, and turns every locked minute into your study record. PICK WHAT TO PAUSE Choose apps or whole categories once, like social media and games. Mosslock uses Apple's Screen Time features, so the apps you choose stay private, even from us. START A SESSION Pick a subject and a length (25, 50 or 90 minutes) and start. Paused apps show your moss instead of the feed. When the time is up, they open again on their own. A STUDY RECORD YOU CAN TRUST Only time your apps were really locked is counted. See today, this week and each subject at a glance. GROW A MOSS GARDEN Every finished session plants a patch of moss. Longer sessions grow bigger moss. Stop early and that patch withers. Keep your streak going day after day. FREE - Pause any apps and categories during sessions of up to 50 minutes - Up to 3 subjects - The last 7 days of records - Moss garden and Home Screen widget MOSSLOCK PRO - Your full study history - This month's report with a subject breakdown - Weekly study hours that start on their own - Strict mode for exam season - Study sessions up to 4 hours - Unlimited subjects PRIVATE BY DESIGN No account, no ads, no analytics. Your study records and the apps you choose stay on your iPhone. Purchases are processed by Apple and managed by RevenueCat with an anonymous ID. YOU'RE ALWAYS IN CONTROL You can stop a session in the app, and you can turn off Mosslock's Screen Time access in the Settings app at any time. Mosslock is a study tool, not medical treatment.
