Fasten — Private Fasting Tracker for iPhone Most fasting apps today seem to focus on subscriptions, cloud accounts, social features, and endless upsells. I built Fasten because I wanted the opposite. Fasten is a private fasting tracker designed for people who simply want to track their fasts without creating an account, sharing personal data, or paying for features they don't need. What makes Fasten different? Privacy first * No account required * No personal data collection * Your fasting data stays on your device Simple by design * Start and stop fasts in seconds * Clean, distraction-free interface * No unnecessary complexity Track your progress * Monitor fasting sessions * View your fasting history * Stay motivated with clear progress tracking Flexible fasting schedules * 16:8, 18:6, OMAD, and custom fasting plans * Works whether you're new to fasting or experienced Built exclusively for iPhone * Native iOS experience with Liquid Glass * Fast, lightweight, and battery-friendly * Designed to feel at home on Apple devices I created Fasten because I was frustrated by fasting apps that felt more focused on subscriptions and data collection than helping people build healthy habits. If you're looking for a fasting app that respects your privacy and stays out of your way, I'd love to hear your feedback. Questions, feature requests, and honest criticism are all welcome.
