Display names are filtered automatically, group fasts can only be hosted by people we have approved, and every profile, host and coach update can be reported or blocked from inside the app. Reports are reviewed within 24 hours and offending content and accounts are removed. Our Community Guidelines are in the app under Settings → Community, and at https://fastiq.fit/community-guidelines. FastIQ is an education and tracking tool, not medical advice. Talk to a qualified healthcare professional before starting any fasting or nutrition program, especially if you are pregnant, nursing, under 18, or managing a medical condition. Fasts longer than 48 hours carry real health risks and are not safe for everyone.

Tired of fiddly logging? With LuniFIT, you just chat, and the AI takes care of the rest. "Toast and eggs for breakfast" "Weight 65 kg" "Two glasses of water and a 30-minute run" Type it like you'd say it, snap a photo, or just speak. Luni sorts out the calories, nutrition, and records, then gently coaches your next step. What Luni helps with • Meals: name what you ate, or take a photo, and calories and nutrition are logged automatically • Workouts: say the exercise and amount, and calories burned are calculated • Fasting: a live intermittent fasting timer with routine reminders • Weight: trends and progress toward your goal • Water: track your daily intake, glass by glass • Cycle: log your period and see predicted dates and phases Three ways to log • Naturally by chat: type, dictate, or send a photo, even several things in one sentence • The + button: quick entry from a bottom sheet • Stats tab: review and add directly Luni remembers, and reaches out first Luni is a companion, not a nag.

Verdict
The clearest difference is rating: FastIQ at 4.9 against LuniFIT's 1.0. FastIQ also leads on ratings volume (37 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. FastIQ sells 2 in-app purchases, starting at $9.99 per month and LuniFIT sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
FastIQ holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: FastIQ has 37 ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly fortnightly. Both last shipped on October 31, 2026.
