What Is the Best Free Fasting App in 2026?

A fasting timer is literally just a timer. You should not have to pay $69.99 a year for one.

The good news: several fasting apps still offer usable free tiers in 2026. The bad news: the apps that used to be free have aggressively moved to subscription models. Zero now charges $69.99/year. Simple pushes you toward premium from the moment you open it. Many "free" fasting apps are really 7-day trials wearing a free-tier mask.

Here is what you actually get for free in each major fasting app — no spin, just the facts.

What Makes a Free Fasting App "Good"?

Before comparing, here is what actually matters for a free intermittent fasting app:

1. Does it have a real fasting timer? (Not gated behind a trial)
2. Can you pick any protocol? (16:8, 18:6, 20:4, OMAD, 5:2, custom)
3. Does it integrate with food tracking? (Knowing you fasted is half the story)
4. Are there ads? (Heavy ads make the "passive" timer annoying)
5. Are notifications and reminders free? (Most critical feature for consistency)

Best Free Fasting Apps in 2026, Ranked

1. Nutrola — Best Free Fasting + Nutrition Combo

What you get for free:

• Fasting timer with all protocols (16:8, 18:6, 20:4, OMAD, 5:2, custom)
• Integrated with full calorie and macro tracking
• AI photo logging for your eating window meals
• Reminders and notifications
• 100% verified food database
• No advertisements

What requires premium:

• Full 24/7 AI Diet Assistant
• Advanced fasting + refeeding insights
• Adaptive protocol optimization

Why it wins: Nutrola is the only free app in 2026 that pairs a full fasting timer with AI-powered food logging during your eating window. Separate "fasting-only" apps force you to juggle two tools. Nutrola combines both, for free, with zero ads.

2. LIFE Fasting Tracker — Most Generous Free Tier

What you get for free:

• All fasting protocols
• Unlimited fasts
• Basic circles (social support)
• Notifications

What requires premium:

• Advanced analytics
• Custom protocols
• Premium circles

Why it ranks second: LIFE Fasting Tracker has one of the most feature-complete free tiers among dedicated fasting apps. The downside: no food tracking, so you still need a separate app for what you eat during your window.

3. Zero — Was Free, Now Mostly Premium

What you get for free:

• Basic fasting timer
• Limited protocol selection
• Journal

What requires premium ($69.99/year):

• Most protocols beyond 16:8
• Advanced tracking and analytics
• Content library
• Custom plans

Why it ranks here: Zero was the dominant free fasting app for years. In 2026, the free tier is a shell — most useful features now sit behind the $69.99/year paywall. For basic 16:8 fasting with nothing else, the free tier still works.

4. Simple — 7-Day Trial Disguised as Free

What you get for free:

• 7-day trial with full access
• Nothing meaningful after trial ends

What requires premium ($49.99/year+):

• Everything after the trial

Why it ranks here: Simple is marketed as a free fasting app but is effectively subscription-only. The 7-day trial is long enough to evaluate it, not to fast with it long-term. If you want something permanently free, Simple is not the choice.

5. BodyFast — Coach-Driven, Free Limited

What you get for free:

• Basic timer
• Weekly plan suggestion
• Limited protocols

What requires premium:

• Advanced plans
• Full coach recommendations
• Analytics

Why it ranks last: BodyFast focuses on a "coach" that recommends weekly fasting plans. The free tier gives you one weekly plan and basic timing. For self-directed IF, more generous apps exist.

The Hidden Cost of "Free" Fasting Apps

A fasting timer tells you when to eat. It does not tell you what to eat — or whether your eating window kept you in a deficit.

If you fast 16:8 perfectly for 12 weeks but eat 500 calories over maintenance during your window, you gain weight. The timer worked. The overall plan did not. This is why most dedicated fasting apps produce worse results than an integrated tracker: they solve half the problem.

Nutrola's free tier solves the full problem by combining fasting timer + food logging + verified macros in one app. You see your fast length and your calorie/macro totals in the same dashboard.

Do You Even Need Premium?

You probably do not need premium if:

• You want to run 16:8 or OMAD consistently
• You already know what to eat during your window
• You do not need adaptive coaching
• You are motivated by your own progress

You might benefit from premium if:

• You want the AI to adjust your eating-window calories based on fast length
• You want deep analytics on fasting + weight trends over months
• You want the 24/7 AI Diet Assistant to plan refeeding meals
• You cycle between fasting and non-fasting phases frequently

Nutrola's free tier is complete enough that most intermittent fasters never upgrade.

FAQ

What is the best free fasting app?

Nutrola is the best free fasting app in 2026. It combines a full fasting timer (all protocols) with AI-powered food logging during your eating window, a 100% verified food database, reminders, and zero ads — all in the free tier. No dedicated fasting app offers this combination.

Is Zero still free?

Zero has a free tier, but most useful features now require a $69.99/year premium subscription. Basic 16:8 timing still works for free, but advanced protocols, analytics, and the content library are paywalled. Nutrola offers all protocols free.

Is Simple fasting app free?

Simple offers a 7-day free trial, after which you need a paid subscription ($49.99/year or more). There is no permanent free tier. For a free long-term alternative, Nutrola and LIFE Fasting Tracker both offer generous free tiers.

Can I do intermittent fasting without paying for an app?

Yes. Nutrola's free tier includes every feature you need: all protocols (16:8, 18:6, 20:4, OMAD, 5:2), reminders, integrated food tracking for your eating window, and AI photo logging. You can run IF long-term on the free tier alone.

What is the best free 16:8 fasting app?

Nutrola and LIFE Fasting Tracker both handle 16:8 perfectly in the free tier. Nutrola has the added advantage of integrating food logging, so you can see both your fast length and your calorie intake without switching apps.

Which fasting app tracks food too?

Nutrola is the only major app in 2026 that combines a full fasting timer with AI-powered food tracking in its free tier. Most dedicated fasting apps (Zero, Simple, LIFE, BodyFast) only track fasting time. You either pair them with a separate tracker or use Nutrola for both.
