Meet your fasting companion — a tamagotchi-style virtual pet that grows as you fast. Track water, log how you feel, and make fasting an easy, regular habit
Fasting Friend is a calm, privacy-first fasting timer with a twist: a virtual companion that evolves through 15 stages as you fast — from a tiny egg to a crowned eagle.
Whether you're doing your first 16:8 or a 7-day extended fast, Fasting Friend guides you with science-backed milestones, gentle reminders, and real-time progress tracking.
- HOW IT WORKS -
Pick your fasting style and tap Start. Your companion begins to grow. As you hit milestones like ketosis activation, autophagy, and growth hormone surges, you'll see your friend evolve and learn what's happening in your body — with links to published research.
- MULTIPLE FASTING MODES -
• Standard: Timed fasts from 24 hours to 7 days with milestone tracking and companion evolution.
• Intermittent: Daily patterns including 16:8, 18:6, 20:4, and OMAD with streak tracking and a GitHub-style consistency heatmap.
• Freestyle: Open-ended fasting with no set end time — stop when you're ready.
• Cultural: First-class support for faith-based fasting traditions, including Ramadan (dawn-to-sunset with location-aware Fajr/Maghrib times), Yom Kippur (Kol Nidre to Havdalah), and Ekadashi (lunar calendar with named observances). The app auto-detects upcoming dates and respects each tradition's specific rules.
