Pause social. Keep calls, texts and a bedside alarm. Need to stay reachable without getting pulled into a feed? RetroFold combines selected-app blocking with a retro phone keypad, clock and local alarm. Use your phone for what you need, then put it down. CHOOSE WHAT TO BLOCK Allow Apple Screen Time access, choose distracting social apps or websites, select a duration and start. Keep Phone and Messages out of your selection if you want to use them. Pick 15 minutes, 1 hour, 2 hours or a custom duration. These are times for the same blocking feature, not separate modes. Shields lift at expiry, and you can end early. KEEP IMPORTANT PEOPLE CLOSE Use the retro keypad, system contact picker and Apple's message composer. To receive alerts only from chosen people, configure allowed people and callers separately in iPhone Focus. RetroFold does not read communications, judge their importance or switch iPhone Focus on or off. A BEDSIDE CLOCK, NOT ANOTHER FEED See a large clock and date. Schedule a local alarm with optional daily repeat. The alarm requires notification permission and follows Silent, Focus and other device settings; it does not behave identically to the built-in Clock alarm. A LITTLE RETRO CHARACTER Choose pink or white LCD styling, tap the keypad with sound and haptics, and keep a private note. A completed focus session earns an in-app letter card you can save or share. Letters are a bonus for any completed duration, not a 15-minute-only feature. No actual SMS is sent as a reward. YOUR PHONE, YOUR CHOICE Screen Time permission is required for app blocking. RetroFold does not replace iOS, the Home Screen, Phone, Messages or incoming-call screens. Phone and message actions finish in Apple system interfaces. iPhone Focus notification filtering must be turned off separately. No account, ads, analytics SDK, subscription or in-app purchase. App settings, notes and session records stay on your device. Sharing is optional and uses the destination you select. App interface languages: English and Korean.
