Quick answer: Fasted has the strongest free tier with no subscription required for core features. If you want premium, it's a one-time-style annual fee of $29.99 — not a monthly subscription. DoFasting at $35/month ($420/year) is the most expensive option in the category for what it delivers.

Intermittent Fasting Apps With No Subscription (2026 Breakdown)

DoFasting charges $35 a month. Let that sit for a moment. That's $420 a year for an app whose primary function is tracking time. Your stopwatch app is free. A kitchen timer costs $8. DoFasting is charging magazine subscription rates for a countdown clock with a meal library attached.

The fasting app market has a subscription pricing problem. Several apps have adopted aggressive monthly billing because it generates high lifetime revenue from users who forget to cancel — not because the features justify it. This article breaks down what you actually need to track a fast, which apps charge reasonably for it, and which ones are genuinely free.

What You Actually Need to Track Intermittent Fasting

Strip away the marketing and a functional fasting tracker requires four things:

1. A timer that starts when your fast begins and counts up to your target
2. A notification that fires when your eating window opens (and optionally when it closes)
3. Basic stats — how long was your last fast, what's your completion rate, are you trending better or worse
4. A protocol setting — 16:8, 18:6, OMAD, or custom, with your eating window times saved

That's it. Everything else — AI coaching, meal plans, recipe libraries, behavioral check-ins, color-coded food systems — is add-on content, not core fasting infrastructure.

The question of whether you need a subscription to get these four things is the question this article answers. You don't.

Fasting Apps That Are Genuinely Free

Fasted — Best Free Tier in the Category

Fasted's free tier includes the core fasting timer, protocol selection, streak tracking, and basic fasting stats. There's no credit card required, no trial period that converts to billing, and no feature degradation over time.

The free tier is usable long-term. This distinguishes Fasted from apps like DoFasting and Zero, where the free tier is a deliberate preview designed to push you toward subscription rather than a functional product on its own.

What the free tier includes:

• Full fasting timer with any protocol (16:8, 18:6, OMAD, 5:2, custom)
• Start/end notifications
• Streak tracking
• Basic fasting history and completion stats

What requires Fasted premium ($29.99/year):

• Buddy system for shared accountability
• Advanced analytics (completion rate by day of week, trend lines, personal records)
• Extended fasting history beyond 30 days
• Home screen widget

For users who just want to track their fast without paying, the free tier covers everything essential. The premium upgrade is legitimately optional — it adds features, not access to the core function.

Life Fasting Tracker — Old but Free

Life has a functional free tier and has maintained it since 2016 without significantly degrading it. The app is dated — it hasn't had major design or feature updates in some time — but the timer works, notifications are reliable, and you can track fasting indefinitely without paying.

The free tier includes basic group (social) features that some users find motivating. Premium adds some analytics and customization. The app is not actively developed in the same way newer apps are, but for users who just want a free timer that works, it's a legitimate option.

Fastient — Free with Optional Donation

Fastient is a simple, no-frills fasting tracker. It's genuinely free with no subscription and no premium tier — the developer accepts optional donations. The interface is minimal by design.

Suitable for users who want maximum simplicity and zero recurring cost. Not suitable for users who want streak systems, social features, or polished design.

Apps With Reasonable Paid Models (Not Monthly Subscriptions)

The subscription model is a choice, not a technical requirement. Some apps have chosen different pricing structures.

Fasted Premium: $29.99/year. Annual billing, not monthly. Equivalent to $2.50/month if you think about it monthly, but billed once. This is the right model for an app in this category — you pay once a year for a tool you use every day.

Zero: $69.99/year, billed annually. More expensive than Fasted but structured as an annual payment rather than monthly. The free tier is limited but present.

If you're comparing to DoFasting's $35/month: Fasted's annual premium is what you'd pay in less than one month of DoFasting's standard rate.

Apps You Should Avoid (Subscription Pricing That Isn't Justified)

DoFasting — $35/month ($420/year)

At full price, DoFasting is the most expensive fasting app on the market by a significant margin. The features it provides over a free fasting tracker:

• Meal plan library (recipe database, not personalized meal planning)
• Structured challenge programs (14-day, 28-day)
• "AI coaching" (rule-based automated messaging)

None of these features require $420/year to deliver. The meal library is content that could be acquired from free recipe sites. The structured programs are valuable for some users but don't justify subscription rates. The AI coaching is, by most user accounts, not meaningfully adaptive.

DoFasting's pricing is a reflection of their customer acquisition cost (high) and their business model (monthly subscriptions with friction-heavy cancellation), not the value of the features.

Apps That Use "Free" as Marketing

Several apps advertise "free forever" or "no subscription" during onboarding and then present a paywall for core functionality. Common patterns:

• Timer works for free, but history beyond 3 days requires subscription
• First 7 days free, then billing starts automatically
• Free tier that removes after initial setup period

Read App Store or Google Play reviews specifically mentioning "free tier" before downloading any app that emphasizes free access in its marketing. The reviews will tell you what the actual free experience is.

The Real Cost Comparison

The spread from $0 to $420/year for the same core functionality is extraordinary. It reflects different business models, not different product quality.

What Premium Fasting App Features Are Actually Worth Paying For

If you're going to pay for a fasting app, here's what's worth money and what isn't:

Worth paying for:

• Streak tracking with robust history (keeps you accountable over time)
• Buddy/social accountability systems (evidence-backed adherence improvement)
• Detailed trend analytics (identifies patterns you can act on)
• Reliable notifications on Android, including manufacturer-specific battery optimization handling

Not worth paying for:

• AI coaching that isn't actually adaptive
• Meal plan libraries (free recipe resources are equivalent)
• Guided "challenges" if you already know your protocol
• Features you'd need to remember to use, rather than features the app surfaces automatically

The free vs. paid fasting app comparison goes deeper on what the premium tiers across all major apps actually include and whether each is worth the cost.

FAQ

Q: Is there a truly free intermittent fasting app that doesn't push subscriptions? A: Yes. Fasted's free tier and Fastient are both genuinely free without subscription pressure. Life Fasting Tracker also maintains a functional free tier. The key difference from "freemium" apps is that core fasting functionality — timer, notifications, basic stats — is included in the free version without artificial limitations designed to force upgrades.

Q: Is there a one-time purchase option for fasting apps? A: Very few fasting apps offer a true one-time lifetime purchase. Most have moved to annual subscriptions. Fasted's $29.99/year is structured as an annual payment (not monthly), which is the closest to a one-time purchase model in the current market. Fastient accepts one-time donations rather than subscriptions.

Q: Why do fasting apps cost so much? A: The expensive ones (DoFasting primarily) have high customer acquisition costs from paid advertising. Monthly subscription billing is structured to recover those costs over a user's lifetime and generate recurring revenue. Apps without large ad budgets — including Fasted — can price much more reasonably because they're not funding marketing machines.

Q: What happens if I stop paying for a fasting app subscription? A: It depends on the app. Fasted's premium features become unavailable, but your data is retained and the core free tier continues working. Some apps restrict access to your fasting history when you downgrade — check the cancellation terms before subscribing to any app to understand what you'd lose.
