FastLite: Intermittent Fasting
16:8 Fasting Timer & Tracker
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
One ring shows your whole fast, and your buddy Tuanzi stays till mealtime. 16:8, 18:6 or 5:2, fasting stages, streaks, weight and water in one calm app.
Intermittent fasting you can actually stick with.
FastLite does one thing well: a clean fasting timer with a big progress ring, a friendly orange buddy named Tuanzi, and zero pressure. No lectures, no guilt, just gentle support until mealtime.
