Best Fastic Alternatives in 2026

Why People Look for a Fastic Alternative

Fastic is a fasting-first app: timers for 16:8 and other protocols, hydration reminders, step tracking, and educational content, with food logging bolted on around the fasting windows. The common frustrations: the free tier is heavily limited, Plus pricing feels high for what is fundamentally a timer (pricing varies with promotions, but typically lands in the $40–75-a-year range as of mid-2026), the upsell pressure is constant, and the food tracking is too shallow to answer the question that actually determines results — what and how much you ate in your eating window. Our Fastic review has the full breakdown; here are the alternatives, depending on which half of Fastic you actually used.

What to Look for in a Fastic Alternative

• Fasting timer vs food tracking — decide which one you actually need. Most apps do one well, not both.
• Free tier honesty — fasting timers are simple software; you shouldn't pay much for one.
• Eating-window nutrition — fasting works through calorie control. An app that shows what you ate in your window matters more than the timer.
• Upsell pressure — Fastic's constant Plus prompts are a top complaint. Several alternatives are calmer.

Fastic Alternatives at a Glance

1. Bento Bunny — Best for the Food Side, Free

Here's the uncomfortable truth about fasting apps: intermittent fasting works mainly by limiting how much you eat, and a timer can't see your plate. Bento Bunny covers the half of the equation Fastic never did well — photograph your meal during your eating window and the AI logs calories and macros in seconds, with barcode and text input included. It's free during the iOS beta with no Plus tier or upsell screens, and on iOS 26 and later the AI runs on-device, so meal photos never leave your phone. Pair it with any free fasting timer (or your phone's clock) and you have a more complete system than Fastic Plus.

Best for: Fasters who want to know what their eating window actually contains.

2. Zero

The best-known dedicated fasting timer. Clean design, flexible protocols, mood and streak tracking, and a free tier that covers the core timer properly. The paid tier adds insights and content, but you can fast indefinitely without paying — which is more than can be said for Fastic's free experience.

Best for: People who want a serious fasting timer and nothing else.

3. Simple

The closest like-for-like Fastic replacement: fasting timer plus coaching, quizzes, and an AI assistant that answers questions during fasts. Subscription-based with similar pricing energy to Fastic, and similar upsell enthusiasm — but the coaching content is generally rated more useful.

Best for: People who liked Fastic's hand-holding and want better hand-holding.

4. YAZIO

A proper calorie tracker with a built-in fasting timer — the two halves of Fastic in one app, with the food side done much better. The free tier is generous, and PRO (which unlocks the fasting plans) runs roughly $30–50 a year as of mid-2026. Database logging is slower than photo AI and skews European. Read our YAZIO review.

Best for: People who want fasting and food tracking in one subscription — or none.

5. Lifesum

Lifestyle tracker with fasting meal plans among its features. More polished than Fastic, with food logging, habits, and recipes; Premium at around $50 a year as of mid-2026, and a thin free tier. See our Lifesum review.

Best for: People who want fasting as one feature inside a broader wellness app.

How to Choose

If you only need the timer, Zero's free tier ends the search. If you want the coached experience, Simple. If you want one app for both halves, YAZIO. And if you've realised the timer was never the hard part — that results come from what's eaten in the window — pair a free timer with Bento Bunny's free AI food logging and you'll spend $0 on a setup that beats Fastic Plus.
