7 Best Fastic Alternatives for Intermittent Fasting in 2026

Best Fastic Alternatives for Intermittent Fasting

Why People Are Looking for Fastic Alternatives

Fastic has been one of the most popular intermittent fasting apps on the market, and for good reason. It offers a clean interface, a fasting timer, and educational content. However, as the app has matured, many users have voiced frustrations: the premium subscription is expensive (often $59.99-$79.99/year), core features are locked behind the paywall, and the app can feel bloated with upsells and pop-ups.

If you have been searching for a Fastic alternative that delivers the same (or better) features without the hefty price tag, you are in the right place. We have tested and compared the top intermittent fasting apps of 2026 so you can find the perfect fit.

1. FastFlow AI — Best Overall Fastic Alternative

Price: Free with optional premium (weekly, monthly, or yearly plans)
Platforms: iOS and Android

FastFlow AI is the standout Fastic alternative for 2026. Where Fastic charges for basic features like additional fasting protocols, FastFlow gives you access to the two most popular protocols (16:8 and 18:6) completely free. The app also includes a built-in AI health coach powered by Google Gemini that can answer your fasting questions in real time — something Fastic reserves for its most expensive tier.

What Makes FastFlow Better Than Fastic?

  • AI Coach included free: Get 3 free AI coaching messages per day. Fastic charges extra for personalized guidance.
  • All-in-one tracking: Fasting timer, water intake, calorie counting, and weight tracking in a single app. Fastic often requires you to use separate tools for comprehensive tracking.
  • Fasting zones visualization: See exactly when your body enters the Anabolic, Catabolic, Autophagy, and Deep Ketosis zones with a beautiful animated timer ring.
  • Calorie scanner: Snap a photo of your food and let the AI estimate calories instantly. No manual searching through databases.
  • No aggressive upsells: FastFlow respects your experience. You will not be bombarded with pop-ups every time you open the app.
  • Affordable premium: Unlock all 5 fasting protocols (including 20:4 and OMAD), unlimited AI messages, ad-free experience, and advanced stats for a fraction of Fastic's price.

Verdict: If you want a modern, AI-powered fasting app that does not nickel-and-dime you, FastFlow AI is the best Fastic alternative available today.

2. Zero — Best Free Fastic Alternative

Price: Free with optional Zero Plus ($69.99/year)
Platforms: iOS and Android

Zero is one of the original intermittent fasting apps and remains a solid Fastic alternative. The free version offers a basic fasting timer with preset protocols and a clean, minimalist design. Zero Plus adds advanced features like fasting statistics, exclusive content from Dr. Peter Attia, and a journal.

Pros

  • Clean, simple interface
  • Good educational content from medical professionals
  • Free fasting timer is functional

Cons

  • No water tracking or calorie counting — you need separate apps
  • No AI coaching feature
  • Premium is actually more expensive than Fastic at $69.99/year
  • Limited fasting zone insights on the free tier

Zero is a good choice if you only need a timer, but if you want comprehensive health tracking, FastFlow AI offers significantly more value.

3. BodyFast — Best for Guided Fasting Plans

Price: Free with optional Coach plan ($59.99/year)
Platforms: iOS and Android

  • Good variety of fasting methods

Cons

5. LIFE Fasting Tracker — Best for Social Fasting

Pros

  • 100% free

  • Founded by Dr. Jason Fung, a respected fasting researcher

Cons

  • Very basic feature set — just a timer and social features
  • No meal tracking, calorie counting, or water tracking

6. Fastient — Best for Data Nerds

  • Detailed fasting history and charts
  • Journaling feature to track how you feel
  • Web version available

Cons

  • Very basic UI — not visually appealing

  • Meal recipes and calorie tracking
  • Progress tracking with body measurements

Cons

  • Expensive — similar pricing to Fastic
  • Heavy onboarding quiz that feels like a sales funnel
