Fastic Review: Fasting Tracker, Plus Cost & Is It Worth It? (2026)

Fastic comes at weight loss from the opposite direction to most apps in this category: the fasting window is the product, and food tracking is the supporting act. For the millions of people doing 16:8 or similar protocols, that ordering makes sense. This review covers what Fastic does well as a fasting companion, what Plus costs, and where its food tracking runs out of depth.

What Is Fastic?

Fastic is a German-built intermittent fasting app with a very large user base, centred on a fasting timer that tracks your eating and fasting windows, visualises the metabolic phases of a fast, and nudges you through the hungry hours. Around that core it adds water tracking, step counting, educational content, challenges, and — increasingly — food logging, including an AI-assisted food scanner for photos and barcodes.

Fastic Features

• Fasting timer — 16:8, 18:6, OMAD and other protocols, with phase visualisation during the fast.
• Food logging with a database, barcode scanning, and an AI photo scanner on paid tiers.
• Water and step tracking built in.
• Courses and challenges — bite-sized education and community accountability.
• Statistics on fasting streaks, weight trend, and habits.

Fastic Cost: Free vs Plus

The free tier covers the core fasting timer, basic water and step tracking, and limited food logging. Fastic Plus typically lands in the $30–75/year range as of mid-2026 — pricing varies widely with frequent promotional discounts, so check the current offer — and unlocks all fasting protocols, the full courses, the AI food scanner, recipes, and deeper statistics. As fasting apps go it's priced similarly to Zero's paid tier and below coaching programs like Noom (see our Noom alternatives guide for that comparison).

What Fastic Does Well

The fasting experience is genuinely good. The timer is clear, the phase visualisation makes a 16-hour fast feel like progress rather than deprivation, and the streak mechanics suit fasting well — a fast is binary in a way a diet isn't. The education is beginner-friendly, covering what to expect hour by hour. And the holistic extras (water, steps, challenges) keep everything in one place for people who want a simple habit dashboard rather than a nutrition lab.

Where Fastic Falls Short

Food tracking is the supporting act, and it shows. The database is thinner than dedicated trackers, the logging flow is slower, and the AI scanner — a welcome addition — sits behind Plus and trails purpose-built photo trackers on mixed meals. Calorie and macro depth is limited: if you're tracking protein targets or a precise deficit alongside your fasts, Fastic's tools feel basic next to a real tracker. And the paywall placement is aggressive — many of the features that make the app sticky, including the scanner, require Plus.

Fasting Window + What You Eat: The Missing Half

Here's the honest gap: fasting controls when you eat, but results still depend on what and how much lands in the eating window. An eight-hour window can comfortably hold a calorie surplus. That's why many serious fasters run two tools — a fasting timer plus a proper food tracker — and why the food tracker needs to be fast: you're logging a whole day's food in a compressed window, often in two big meals. Bento Bunny fits that slot well: one photo logs the whole plate in about five seconds, barcode scanning is free, and the AI runs on-device on iOS 26+. Core features are free with no subscription. See Bento Bunny vs Fastic for the side-by-side.

Who Should Use Fastic?

Fastic is a strong pick if intermittent fasting is your primary strategy and you want a motivating, well-designed timer with light tracking around it. Beginners to 16:8 in particular will get value from the phase education and streaks — the free tier is enough to find out if fasting suits you.

The Bottom Line

Fastic is one of the best fasting companions on the market, and it's honest work: the timer, education, and streaks genuinely help people hold a fasting habit. Its food tracking, though, is a convenience feature rather than a serious tool — fine for a rough idea, thin for real calorie or macro goals. If fasting alone is moving the scale for you, Fastic is enough. If it isn't, keep Fastic for the windows and pair it with a fast, free photo-first tracker like Bento Bunny for the plates.
