7 Best Free Habit Tracker Apps in 2026
A hands-on comparison of the best free habit tracker apps for iPhone and Android. Find the right app for building lasting habits without paying a subscription.
There are dozens of habit tracker apps on the App Store and Google Play. Most of them lock core features behind a subscription. Some are genuinely free. And a few actually help you build habits that last.
We tested the most popular options to find the ones worth your time. Here's what stood out.
What We Looked For
Not every habit tracker works the same way. We evaluated each app on:
- Free plan generosity — Can you actually use it without paying?
- Core tracking features — Scheduling, reminders, completion logging
- Metrics that matter — What does the app measure, and does it encourage long-term behavior?
- Design and usability — Is it pleasant to use daily?
- Platform availability — iPhone, Android, web, or all three?
The Best Free Habit Tracker Apps
1. Keel
Platforms: iOS, Web | Price: Free
Keel takes a fundamentally different approach to habit tracking. Instead of counting streaks, it measures your bounce-back rate — how quickly you return to a habit after missing a day. This reframes missed days as neutral events rather than failures.
What makes it stand out:
- Bounce-back rate as the primary metric — tracks resilience, not perfection
- Goal linking — connect habits to meaningful outcomes so you see which habits actually move the needle
- Flexible scheduling — daily, specific days, time-of-day, or exact times
- AI Habit Coach — chat-based planning to help you structure your day
- No habit limits on the free plan
Best for: People who've tried streak-based apps and found them stressful. If you want to build sustainable habits without the guilt of "breaking a streak," Keel is built for that.
What's missing: No Android app yet (web works on any device). No social features.
2. Loop Habit Tracker
Platforms: Android | Price: Free (open source)
Loop is the gold standard for free habit tracking on Android. It's fully open source with no ads, no subscriptions, and no account required.
What makes it stand out:
- Completely free with no limits
- Detailed charts and statistics (streaks, frequency, calendar view)
- Flexible scheduling (daily, weekly, specific days)
- No internet connection required — everything stays on your device
- Clean, Material Design interface
Best for: Android users who want a no-nonsense, privacy-focused tracker with solid analytics.
What's missing: iOS not available. No cross-device sync. No web version. Interface feels utilitarian.
3. Habitify
Platforms: iOS, Android, macOS, Windows, Web, Apple Watch, Wear OS | Price: Free (3 habits) / Premium from $2.49/mo (billed annually)
Habitify is one of the most polished habit trackers available. The free tier is limited to 3 habits, but the experience is excellent.
What makes it stand out:
- Beautiful, intuitive interface across all platforms
- Detailed analytics with streak tracking and completion rates
- Time-of-day grouping (morning, afternoon, evening)
- Apple Watch and widget support
- Cross-platform sync
Best for: People who want a premium experience and only need to track a few habits.
What's missing: 3-habit limit on free is restrictive. Premium gets expensive. Streak-focused metrics can create pressure.
4. Habitica
Platforms: iOS, Android, Web | Price: Free / Optional subscription $4.99/mo
Habitica gamifies habit tracking with an RPG-style interface. Complete habits to level up your character. Miss them and you lose health points.
What makes it stand out:
- Full gamification with character customization, quests, and party system
- Supports habits, dailies, and to-dos
- Social accountability through guilds and challenges
- Generous free tier with most features available
- Surprisingly effective motivation through game mechanics
Best for: People who respond to game-style rewards and want a social accountability system.
What's missing: The game mechanics can feel punishing when you miss days. Interface is busy. Gamification wears off for some users.
5. Streaks
Platforms: iOS, iPad, Mac, Apple Watch, Vision Pro | Price: $5.99 one-time purchase
Streaks is a premium app with a one-time purchase — no subscription. It's Apple-native, beautifully designed, and deeply integrated with the Apple ecosystem.
What makes it stand out:
- One-time purchase (no recurring fees)
- Deep Apple ecosystem integration (Health, Shortcuts, Siri, widgets)
- Clean circular progress design
- Negative habits (tracking things to avoid)
- Apple Watch app that works independently
Best for: iPhone users willing to pay once for a polished, Apple-native experience.
What's missing: Limited to 24 habits. No Android or web version. Streak-focused by design — missing a day resets your counter.
6. Notion (with templates)
Platforms: iOS, Android, macOS, Windows, Web | Price: Free
Notion isn't a habit tracker by default, but its flexibility means you can build exactly the tracking system you want using templates or from scratch.
What makes it stand out:
- Completely customizable — build any tracking system you can imagine
- Hundreds of free habit tracker templates available
- Database views: calendar, table, board, timeline
- Works alongside notes, tasks, and other life systems
- Generous free plan
Best for: People who already use Notion and want everything in one place.
What's missing: Requires setup and configuration. No built-in reminders for habits. No dedicated analytics. The flexibility is both its strength and weakness — you have to build the system yourself.
7. Clockify
Platforms: iOS, Android, macOS, Windows, Web | Price: Free
Clockify is primarily a time tracker, but its habit-tracking capabilities make it a solid free option — especially if you want to track how long you spend on habits.
What makes it stand out:
- Completely free with unlimited tracking
- Time-based tracking shows how much time you invest in each habit
- Available on every major platform
- Team features for accountability partners
- Pomodoro timer built in
Best for: People who want to track time spent on habits, not just completions.
What's missing: Not purpose-built for habit tracking. The time-tracking interface adds friction for simple "did it / didn't do it" habits.
How to Pick the Right One
The best habit tracker is the one you'll actually use. A few questions to ask yourself:
How many habits do you want to track? If it's more than 3, Habitify's free plan won't cut it. Keel, Loop, Habitica, and Clockify all offer unlimited free tracking.
What phone do you use? Loop is Android-only. Streaks is iOS-only. Keel, Habitify, Habitica, Notion, and Clockify work on both (Keel via web on Android).
How do you feel about streaks? If streaks motivate you, Streaks and Habitify lean into that. If streaks stress you out, Keel's bounce-back approach might be a better fit.
Do you want simplicity or flexibility? Loop and Streaks are focused and simple. Notion is infinitely flexible. Keel and Habitify sit in the middle — structured but not rigid.
Our Take
Most habit apps measure the wrong thing. Counting consecutive days feels motivating, but research shows it's how quickly you bounce back after a miss that actually predicts long-term success.
That's why we built Keel differently. But the right app depends on you — your platform, your style, and what keeps you coming back.
The worst habit tracker is the one collecting dust on your home screen. Pick one, start small, and build habits that actually stick.
