About

Serelle

Features
Read full description

You downloaded three meditation apps. You've collected 300 guided meditations you'll never listen to. You just want to sit for 10 minutes. Serelle is a meditation timer. Not a meditation app. Tap once, pick a length, and sit. A 5-point mood check after each session takes 3 seconds. Your streak shows up when you come back the next day. That's it. ใ€What Changes When You Strip Meditation Down to Just a Timerใ€‘ โ€ข No pre-session decisions. You're already sitting โ€” just start โ€ข The week view shows which days you showed up, and your history shows how each session felt โ€ข No notifications saying "You haven't meditated in 3 days" โ€” just a streak that either continues or resets โ€ข When you stop feeling like you need permission to meditate, you meditate more ใ€How It Worksใ€‘ - One-tap start: choose 1, 3, 5, 10, 15, 20, or 30 minutes - Mood check: 5-point scale after each session, with an optional note - Session history: every session and its mood at a glance - Streak: days in a row, plus this week's minutes and your longest streak - Dark/light theme "Why not just use the phone's built-in timer?" โ€” The built-in timer doesn't know you meditated. It doesn't log the session, record your mood, count your streak, or show you your week at a glance. A clock tells time. Serelle tracks practice. "I've tried meditation apps and always stopped." โ€” Most apps make you feel like you're doing it wrong when you skip a day or don't listen to the guide. Serelle has no guides to skip. Your streak resets and you start again. That's the whole system. "Do I need to pay?" โ€” The timer, streak, and mood log are free, with up to 5 sessions a day. Premium removes the daily limit and ads. Price shown before you commit. ใ€Premium Planใ€‘ Unlimited sessions every day, no ads. See in-app for current pricing. Subscription auto-renews unless canceled 24 hours before renewal. Manage in Apple ID Account Settings. Start logging today. Free, no guides required.
