The timer, standard protocols and streaks are free. The features long-term users miss — detailed stats, fasting zones, correlations — moved into Zero Plus at $9.99/month or $69.99/year (August 2026).

What happened to Zero's free features?

Over several years Zero moved formerly free statistics and zone tracking behind the Plus paywall — the most consistent complaint in its recent reviews. The free timer itself remains good.

Does Zero track anything besides fasting?

It has added protein scoring, meal photos and hydration, with sleep and activity arriving via wearable import on Plus. There's no journaling, mood tracking, training or meditation.

Which fasting app has no subscription?

For a bare timer, Zero's free tier or Fastic's basics work fine. Lamplit's free tier includes the live fasting timer with stage tracking plus all nine health domains — its paid tiers add AI volume and integrations, not the timer.

Is intermittent fasting right for me?

Not for everyone. Talk to a clinician first if you're pregnant, underweight, living with diabetes, or have a history of disordered eating. Both Zero's and Lamplit's fasting guidance is educational, not medical advice.

Lamplit vs Zero

The Zero alternative where fasting meets the rest of your health

Zero built the category's cleanest timer and its deepest fasting education. It also moved once-free stats behind Zero Plus and drifted from longevity branding toward protein-and-calorie counting. If fasting is one lever in a bigger health practice for you, here's the honest comparison.

Why people look for a Zero alternative

The paywall migration: long-term users' loudest complaint is once-free features — detailed stats, fasting zones — moving behind the $69.99/yr Plus subscription.

Correlations need Plus and a wearable, and stop at body data (weight, resting heart rate, sleep, glucose). Mood and life context aren't part of the picture.

Identity drift: the App Store subtitle is now 'Protein & Calorie Calculator' — the longevity focus that made Zero famous has blurred.

Timer-reliability grumbles: recent reviews describe fasts that 'never actually started' after sync hiccups.

Where Lamplit takes a different approach

A real timer, plus the reasons

Lamplit's live fasting timer tracks stages and eating windows with reminders — and then correlates fasting with your sleep, mood, training and meals. Was that 18:6 actually worth it? Your data answers.

Honest on fasting depth

Zero's fasting-zone education and expert content go deeper on fasting physiology than Lamplit's. If you want to study fasting as a subject, Zero teaches it better. Lamplit's Genie instead answers your questions in the context of your own data, citing peer-reviewed research.

One subscription, nine domains

Zero Plus costs $69.99/yr for fasting analytics. Lamplit Pro at $5.99/mo covers fasting plus training, nutrition, meditation, cycle and journaling — with the AI included.

No identity drift

Longevity is the product, not a rebrand. Fasting sits beside your Longevity Score, sleep and training — not behind a protein score.
