Best Fasting App in 2026: 9 Apps Compared

Zero is our pick for most people because the free tier covers the core job well: start a fast, see progress, and review your history. Presets cover the common schedules, and the journal and mood tracking help you notice patterns without adding a second app. The design is calm, which matters for an app you open every day.

Zero Plus, listed from $9.99 per month or $69.99 per year in app stores, adds advanced stats, longer history, and extra content. You do not need it to track a daily 16:8 fast. If you want a reliable timer with room to grow, start free and upgrade only when you hit a limit you actually care about.

Fastic suits people who want fasting inside a wider health routine, not just a countdown. The free tier includes a timer, basic stats, and water tracking, and the app adds steps and recipes so meals and movement sit next to the fast. Challenges and reminders help if you tend to start strong and drift after two weeks.

The paid plan opens the full recipe library, deeper stats, and extra programs. That is worth it if you use the recipes and challenges weekly. If you only need a timer, Zero or FastHabit will feel lighter and cheaper. Fastic is best when food and activity tracking matter as much as the fast itself.

BodyFast is a good middle option between a bare timer and a full coaching app. The free tier gives you a weekly plan, fasting tips, and weight tracking, so you get structure without paying on day one. That structure helps beginners who are unsure which schedule to try first, since the app suggests a plan and adjusts the week around it.

Coaching and deeper personalization sit behind a paid plan, and prices vary by store and region, so check the listing before you commit. BodyFast is a strong pick for weight loss goals when you want a plan to follow, but you should still treat its advice as general wellness information, not medical guidance tailored to you.

Simple takes a coaching-first approach. It builds a plan around your goals, then gives daily prompts, food logging, and check-ins to keep you on track. For people who want guidance on what to eat and when, rather than just a timer, that hand-holding can make the difference between a week of fasting and a lasting routine.

The cost is the catch. At $11.99 per month in recent comparisons, or $35.99 per year where that annual option is offered, Simple is a real subscription, not a free timer with extras. Try the trial and check whether you actually open the coaching features daily. If you only use the timer, a free app will serve you just as well.

DoFasting is for people who want a program, not a blank timer. You answer questions about your goals, get a structured plan, and follow daily guidance on fasting windows, meals, and habits. That structure can help if you have tried a free timer before and stopped because no one told you what to do next.

The trade-off is cost and commitment. DoFasting is mostly subscription-based, and pricing varies by the plan length you choose, so check the official site for the current offer in your region. If you prefer to set your own schedule and track it free, skip this one. If you want a guided program for weight loss, DoFasting is one of the more focused options.

Window, sometimes listed as Window Fasting Tracker, keeps the job small: set your eating window, get alerts, and track your fasts. That restraint is a feature. There are fewer menus to learn, fewer prompts to dismiss, and less pressure to buy a coaching plan you did not ask for.

Premium at $9.99 per month adds deeper stats and extra features, but the free tier already covers daily tracking well. Window is a good pick if you find other fasting apps busy or pushy. It is less useful if you want meal plans, recipes, or a coach, in which case BodyFast or Simple fits better.

FastHabit is the quiet option in this list. It tracks fasts, shows streaks, sends reminders, and supports common schedules, without pushing a subscription at every step. The Pro upgrade is listed at $2.99, which makes it one of the cheapest ways to get a fuller fasting tracker if you ever want more than the free tier.

The plain design will not excite people who want challenges, recipes, or coaching. That is also why it lasts: there is little to get tired of. If you already know your schedule and just need a reliable timer that stays out of the way, FastHabit is an excellent free fasting app for weight loss tracking and daily use.

LIFE Fasting Tracker, often called LIFE, adds a social layer to fasting. You can join group fasts, see friends progress, and get encouragement during a longer fast, which helps when willpower dips in the evening. The core timer and tracking are free, so the social part does not require a paid plan to try.

Social feeds are not for everyone. If you prefer private tracking, turn the social features off or pick FastHabit instead. If accountability helps you, LIFE is one of the few fasting apps where group fasts feel like a real feature rather than a bolted-on feed. As with any group fast, do not let a group goal push you past what is safe for you.

Vora is a community-focused fasting tracker with a free core app and an optional one-time upgrade listed at $4.99 in some stores. It covers the basics, timer, history, and community progress, without gating the daily tracker behind a subscription. That makes it a good backup pick if you dislike subscription apps on principle.

The smaller feature set shows if you want meal plans, coaching, or deep stats. Vora will not replace Simple for guided weight loss, and it will not match Fastic for recipes. It will, however, track your fasts reliably and cheaply, and for many people that is the whole job.
