Read full description

Sablo is a fasting timer that stays out of your way. Start a fast, see exactly where you are, and get a nudge when you reach your goal. Begin with a 7-day free trial, then continue monthly or buy lifetime access once. Every feature is included either way. EVERYTHING IN SABLO β€’ 16:8, 18:6, 20:4, OMAD and custom windows β€’ Set the start time after the fact, so a fast you forgot to tap still counts β€’ Edit or delete any past fast β€’ Streaks and your current metabolic phase β€’ A reminder when you reach your goal, and one before your eating window closes β€’ Unlimited history β€’ Trends, averages and completion rate β€’ Home Screen and Lock Screen widgets, Live Activity and Dynamic Island β€’ Weight logging, with optional Apple Health sync β€’ Export your data as CSV whenever you want β€’ Five accent themes IT ALL STAYS ON YOUR PHONE No account. No email. No sign-up. Your fasts never leave the device. That also means nothing to sync, and nothing to lose when you are offline. TWO WAYS TO PAY Start with a 7-day free trial and continue monthly, or pay once for lifetime access. The lifetime option costs less than three months of the subscription and never renews. Sablo describes the phases your body moves through while fasting. It is a timer and a log, not medical advice β€” talk to a doctor before changing how you eat. SUBSCRIPTION TERMS Sablo Premium is billed monthly, at the price shown in the app, after a 7-day free trial. Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within the 24 hours before the current period ends. You can manage or cancel it in Settings β€Ί Apple Account β€Ί Subscriptions. Any unused part of a free trial is forfeited if you buy the lifetime unlock. The lifetime unlock is a single purchase. It does not renew. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
