Intermittent Fasting
The Best Zero Alternatives for iPhone in 2026
Looking for a Zero app alternative? We compare the best fasting trackers for iPhone — from minimalist timers to full nutrition coaches — so you can switch with confidence.
The best Zero alternative depends on what made you want to switch. If Zero feels too data-heavy, a minimalist timer like Orbit is the closest fit. If you want coaching and meal guidance, Simple or Fastic are stronger. If you simply want something free and lightweight, FastHabit is worth a look.
Key takeaways
- Most people leave Zero for one of two reasons: it feels heavier than they need, or the features they want sit behind a subscription.
- Minimalists should look at Orbit or FastHabit: both strip fasting back to a timer and stages, with no food logging.
- If you want guidance, not just a timer, Simple and Fastic lean into coaching, streaks and community.
- Your fasting history matters: most apps can't import Zero data, so check before you switch if your streak history is important to you.
What is Zero? Zero is one of the best-known intermittent fasting apps, offering a fasting timer alongside metabolic data, meal logging and content from health experts.
Why look for a Zero alternative? Most users switch because they want a simpler, quieter tracker, a different pricing model, or an interface that focuses on fasting alone rather than broader nutrition tracking.
Why people look for a Zero alternative
Zero helped define the category, and for a lot of people it's still the right tool. It's polished, well-supported and packed with data.
But "packed with data" is exactly the problem for some fasters. If all you want is to know how long have I been fasting and what stage am I in, a dashboard full of charts, logs and articles can feel like homework. A fasting timer is something you glance at several times a day — and interface weight compounds fast at that frequency.
The three complaints that come up most often are:
- Too much going on. Meal logging, nutrition prompts and content feeds when you only wanted a timer.
- Paywall friction. Features that feel core sitting behind a subscription.
- Habit fit. People fasting for clarity or routine rather than weight loss often don't want calorie framing at all.
Knowing which of those pushed you out matters, because the right replacement is different in each case.
The best Zero alternatives at a glance
| App | Best for | Food logging | Platform |
|---|---|---|---|
| Orbit | Minimalists who want fasting only | No | iOS |
| FastHabit | A simple, no-frills tracker | No | iOS |

1. Orbit — the closest fit if Zero felt like too much
Orbit is our app, so treat this section with the appropriate scepticism — but it exists precisely because of the complaint above. It does fasting and nothing else: a precise timer, live stage cues as your body moves through glycogen depletion into ketosis and autophagy, gentle reminders and streaks.
There's no food logging, no calorie counting and no macro tracking, which is either exactly what you want or a dealbreaker. The design is deliberately quiet — readable at a glance, comfortable in light or dark mode.
Best for: people who want structure without noise. Not for you if: you want nutrition tracking in the same app, or you're on Android.
2. FastHabit — minimal and straightforward
FastHabit takes a similarly stripped-back approach: set a fasting schedule, track streaks, get reminders. It's long-established and has Apple Watch support, which matters if you want to start and stop fasts from your wrist.
Best for: fasters who want a plain, dependable timer. Not for you if: you want detailed stage-by-stage physiological insight.
3. Simple — if you actually want coaching
Simple goes the opposite direction from a minimalist timer. It pairs fasting with nutrition guidance and an AI-driven coach that responds to what you log, aiming to guide rather than just measure.
Best for: people who want to be told what to do next, not just how long they've fasted. Not for you if: you found Zero too involved — Simple asks for more input, not less.
4. Fastic — motivation and community
Fastic emphasises the psychological side: progress stats, encouragement, a large user community and gamified streaks. If your problem with fasting is consistency rather than tracking, that social pull can be the difference.
Best for: fasters who stay consistent when other people are involved. Not for you if: you find gamification and notifications distracting.
5. Life Fasting Tracker — fasting with other people
Life leans into "circles" — fasting alongside friends or family and seeing each other's progress. The shared-accountability model is genuinely effective for some people and completely unappealing to others.
Best for: group fasting and accountability. Not for you if: you'd rather your health data stay private to you.
How to choose (and actually switch)
Work backwards from the reason you're leaving:
- "It was too busy." → Orbit or FastHabit.
- "I wanted more guidance." → Simple or Fastic.
- "I want friends involved." → Life or Fastic.
- "I just want it free." → Compare current free tiers directly; they change often. Our guide to the best free intermittent fasting apps for iPhone goes deeper.
Two practical notes before you move. First, check data portability — fasting apps rarely import each other's history, so if a long streak matters to you emotionally, screenshot it before switching. Second, give the new app a full week. The first two days of any tracker feel strange simply because it isn't the one you had muscle memory for.

Frequently asked questions
What is the best free alternative to Zero?
It depends on the free tier at the time you look, since these change often. Minimalist trackers like Orbit and FastHabit tend to give you a usable fasting timer without paying, while coaching-led apps usually reserve their core value for subscribers.
Can I transfer my Zero fasting history to another app?
Generally no. Most fasting apps do not offer direct imports from one another, so your streak history usually stays behind. If that history matters to you, export or screenshot it before you switch.
Is there a Zero alternative without calorie counting?
Yes. Orbit and FastHabit both focus on fasting alone, with no food logging or macro tracking, which is the main reason people pick them over more comprehensive trackers.
Which Zero alternative is best for beginners?
A simple timer with clear stage explanations is usually easiest to stick with at the start. If you're completely new, read Intermittent Fasting for Beginners: How to Start 16:8 before choosing any app.
Are there Zero alternatives on Android?
Yes — Simple, Fastic and Life Fasting Tracker all run on Android. Orbit is currently iOS only.
