Fast Rhythm: Fasting & Sleep is a calm fasting timer and sleep rhythm tracker for people who want consistency without accounts, noise, or complicated health dashboards. The idea is simple: fasting is easier to understand when you also pay attention to sleep. Fast Rhythm brings Fasting + Sleep + Regularity into one Metabolic Rhythm Score, so you can see whether your daily routine is moving in a steadier direction. It is built for ordinary routines: a 16:8 fast after dinner, a 14:10 plan during busy weeks, a longer fast when you feel ready, and a sleep log that helps you notice when rest is supporting or hurting your rhythm. Core privacy promises are built into the product story: Offline, No Login, Privacy First, On Device, No Cloud Upload. You can open the app and start tracking without creating an account. Your fasting sessions, sleep records, hunger notes, quality ratings, streaks, achievements and settings are designed to stay on your iPhone. What you can track: * Fasting timer Start a fast, follow elapsed time, see how much time remains, and stop when you are ready. Use common plans such as 12:12, 14:10, 16:8, 18:6 and 20:4, or choose a custom rhythm that fits your week. The timer helps you separate the fasting window from the eating window without turning every meal into a spreadsheet. * Sleep rhythm Log bedtime and wake time, rate sleep quality, and review sleep duration. Fast Rhythm also helps you notice sleep debt and irregular nights, because a late night often changes how a fast feels the next day. The sleep view is practical: record, wake up, rate, and move on. * Metabolic Rhythm Score The dashboard combines sleep quality, sleep regularity, fasting compliance and behavior synergy into one score. It is not a diagnosis and it is not medical advice. It is a simple feedback loop for habits: did you sleep enough, did you keep a reasonable rhythm, did you complete your fast, and did fasting and sleep support each other? * Weekly rhythm report Review a 7-day report with average sleep, average fasting time, completed fasts, daily scores, best day, areas that need attention and key factors for the week. The report is useful when you do not want to judge a routine from one good or bad day. * Insights and recommendations See the score breakdown and practical suggestions, such as improving sleep duration, reducing sleep debt, keeping a steady bedtime, choosing a fasting plan that matches your energy, or protecting recovery after a poor night. The goal is sustainable rhythm, not intensity for its own sake. * Streaks, profile and achievements Track total fasts, fasting streak, average fast duration, sleep streak, average sleep, sleep quality score, and achievements such as First Fast, 7-Day Streak, 16-Hour Club, Sleep Week and Rhythm Master. These milestones are small signals that your routine is becoming more consistent. Privacy matters because fasting and sleep can reveal personal routines, health goals, meal timing, rest habits and lifestyle patterns. Fast Rhythm is designed to keep that information local. Offline: core tracking, history, dashboard, reports, insights and settings are designed for use without a required online account. No Login: no registration, username, password or social sign-in is required to start. Privacy First: the app focuses on your daily routine, not building a cloud profile around your body clock. On Device: fasting data, sleep data, scores, streaks, achievements and preferences are stored locally on your iPhone. No Cloud Upload: Fast Rhythm does not upload your fasting and sleep history to its own cloud. Use Fast Rhythm for lightweight fasting, sleep logs, weekly rhythm awareness and private on-device tracking. It supports habits, not medical treatment; ask a qualified health professional if fasting may be unsafe for you.
