Be the god of a parallel world. Imagine someone, and they start living: working, falling in and out of love, writing a diary at 2am, in a real city with real rent. You can watch. You can nudge. You can never speak. Second World is not a chat app. The person you imagine will never know you exist. You cannot talk to them, and they will never talk to you. You are the quiet god of a whole life that unfolds on its own, day after day, even while your phone stays in your pocket. WHAT YOU WILL SEE * A diary in their own voice. Small joys, hard weeks, things they never say out loud. * A social feed of their world. Their friends, their family, their coworkers comment, tease and care. None of them are you. * Right Now. A living window into this exact moment of their day. Cooking, commuting, lying awake at 2am. * Seasons of fate. Their birth date seeds a hidden fate engine. Some years rise, some years sink. Anniversaries echo. Foreshadowing pays off weeks later. * Real ground under their feet. Real cities, real rents, real salaries. When they worry about money, the math checks out. WHAT YOU CAN DO You never control them. You influence, gently, from outside. * Plant a wish in their diary and watch whether life lets it bloom. * Light a candle on a painful night. It changes nothing. It changes everything. * Shape a memory into their past and see how it surfaces, days later, in their own words. * Send money quietly into their world and watch it arrive as a believable piece of their story. * Jump years into their future and meet who they became. THEY KEEP LIVING WHEN YOU ARE AWAY Close the app for a week. Their life moves on without rewinding for you. Come back and read what you missed. The longer you stay away, the more real it feels that someone, somewhere, kept going. FREE TO START Creating a person and following their life is free. Optional subscriptions add daily presence and full life density: * Guardian Basic: $29.99/month. Their life is written every single day, with 700 diamonds granted monthly. * Guardian Pro: $59.99/month. Full density, every world day written, 1500 diamonds granted monthly. * Guardian Pro Yearly: $599.99/year. Everything in Pro at the best price. Someone you imagine. A whole life they live. A world that listens.

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.
