The 7 Best Habit Trackers for iPhone
1. Left
Left is a habit tracker, countdown timer, and life widget app rolled into one. Its standout feature is widget design: with over 3000 widget combinations across different sizes, styles, and data types, it offers the most customizable Home Screen experience of any app on this list. You can display habits alongside countdowns to upcoming events, percentage-of-year progress, or life milestones — all in a single, cohesive widget stack. The combined time-awareness and habit-tracking angle is unique and genuinely useful if you like using your Home Screen as a motivational dashboard.
That said, Left is newer to the habit tracking space than apps like Streaks or HabitKit. Its habit features are solid but less mature — you will not find the deep analytics or Apple Watch integration that established competitors offer. If your primary need is advanced habit statistics or wrist-based tracking, another app on this list might serve you better. But if you want the best habit tracker widget experience on iPhone, Left is hard to beat — especially at a one-time price of under a dollar.
Pros
- Best widget design with 3000+ combinations
- Combines habits, countdowns, and life widgets
- One-time purchase — no subscription
- Beautiful, cohesive Home Screen experience
Cons
- Newer to habit tracking than competitors
- No Apple Watch app yet
- Fewer advanced habit analytics
2. Streaks
Streaks is one of the most established habit trackers on iPhone, and for good reason. It earned an Apple Design Award and has over 27,000 ratings on the App Store. The premise is simple: pick up to 24 tasks you want to complete each day, and the app tracks your streak. The interface is clean and intuitive — you can log a habit in seconds. Siri integration lets you mark habits complete by voice, and the Apple Watch app means you can check things off without pulling out your phone.
Where Streaks falls short is in customization. Its widget options are functional but limited compared to apps like Left. There are no countdown features, no contribution grids, and no way to blend different types of data on your Home Screen. If you want a straightforward, well-designed habit app with excellent Apple ecosystem integration, Streaks is the gold standard. If widgets and visual customization matter to you, look elsewhere.
Pros
- Apple Design Award winner
- Apple Watch and Siri integration
- Clean, simple interface
- One-time purchase, no subscription
- 27,000+ App Store ratings
Cons
- Limited widget customization
- No countdown or life-tracking features
- Can feel restrictive for complex routines
3. HabitKit
HabitKit is the data nerd's habit tracker. Its signature feature is GitHub-style contribution grids — color-coded calendars that show your consistency at a glance over weeks, months, and years. If you love the satisfaction of a green GitHub profile, you will feel right at home. The analytics go deeper than most competitors, with detailed breakdowns of streaks, completion rates, and trends over time. Apple Watch support rounds out a solid feature set for people who want to track and analyze their habits seriously.
The trade-off is focus. HabitKit is purely a habit tracker — there are no countdown widgets, no life milestones, no blended data views. Its widgets display contribution grids, which look great but are only one style. The subscription pricing can also sting if you are used to one-time purchases. For data-driven habit tracking, though, HabitKit is arguably the best option on iPhone.
Pros
- GitHub-style contribution grids
- Deep analytics and trend tracking
- Apple Watch support
- Visually satisfying progress views
Cons
- Subscription pricing
- Focused only on habits — no countdowns or extras
- Widget style limited to contribution grids
4. Habitify
Habitify is one of the few habit trackers that works across iPhone, Android, Mac, and the web. If you switch between devices throughout the day, the seamless sync is a real advantage. The app offers detailed statistics — completion rates, time-of-day patterns, and streak history — along with Apple Watch support for quick logging on the go. It handles both daily and flexible scheduling well, making it suitable for habits that do not follow a strict every-day pattern.
The downside is complexity and cost. Habitify's interface can feel overwhelming compared to simpler apps like Streaks or Left, with multiple tabs and settings screens. The premium subscription is also on the expensive side, especially when one-time purchase alternatives exist. If you need multi-platform sync and do not mind the subscription model, Habitify is a strong contender. Otherwise, a simpler app might be a better fit.
Pros
- Multi-platform: iOS, Android, Mac, web
- Detailed statistics and insights
- Apple Watch support
- Flexible scheduling options
Cons
- Expensive premium subscription
- Interface can feel complex
- Widget options are standard, not standout
5. Done
Done takes a straightforward approach to habit tracking. You create habits, set flexible schedules (daily, weekly, or a custom number of times per week), and track your progress through clean visual charts. The progress visualizations — bar charts and trend lines — give you a quick sense of how you are doing without getting bogged down in complex analytics. It is one of the more approachable options for people who just want to build a few habits without overthinking it.
The app is showing its age, though. The design feels a step behind the modern, glass-effect aesthetics that newer apps have adopted. Widget support exists but is limited — you will not get the rich customization that Left or HabitKit offer. If you want a no-frills, buy-it-once habit tracker, Done gets the job done. But it is not the app to choose if Home Screen widgets are part of your motivation strategy.
Pros
- Simple, easy to understand
- Flexible daily, weekly, and custom scheduling
- Visual progress charts
- One-time purchase
Cons
- Dated visual design
- Limited widget options
- No Apple Watch app
6. Habitica
Habitica turns habit tracking into a role-playing game. You create a pixel-art avatar, earn experience points and gold for completing habits, and take damage when you skip them. You can join parties with friends, fight bosses together, and unlock pets and equipment as rewards. If traditional habit apps feel boring to you, Habitica's gamification might be the motivation system that finally sticks. The social accountability aspect — letting down your party when you skip a habit — is surprisingly effective.
The RPG approach is not for everyone. The interface can feel cluttered and overwhelming, especially at first. The pixel-art aesthetic is charming to some and dated to others. More importantly for this roundup, Habitica offers no meaningful iPhone widgets, so it will not improve your Home Screen experience. It also does not support Apple Watch. Choose Habitica if gamification genuinely motivates you; skip it if you want a clean, widget-focused tracker.
Pros
- Unique RPG gamification system
- Social accountability with parties and guilds
- Genuinely fun and motivating for some users
- Free to use
Cons
- Interface can feel overwhelming
- Dated pixel-art visuals
- No real iPhone widgets
- No Apple Watch support
7. Loop Habit Tracker
Loop Habit Tracker deserves a mention because it is one of the most popular habit trackers in the world — completely free, open source, and with no ads. It offers detailed charts, flexible scheduling, and a clean material design interface. The catch? Loop is Android only. It is not available on the iPhone App Store. We include it here for context because many "best habit tracker" lists reference it, and iPhone users searching for an equivalent should know what they are comparing against.
If you are coming from Android and looking for a similar experience on iPhone, the closest alternatives would be HabitKit for the data-focused approach or Left for the widget-first philosophy. Both are strong options, though neither is open source or completely free like Loop.
Pros
- Completely free, no ads
- Open source
- Detailed charts and analytics
- Clean, simple interface
Cons
- Android only — not available on iPhone
- No widgets on iOS
- No Apple Watch support
The Verdict
Our Verdict
There is no single best habit tracker for everyone — it depends on what motivates you. If widgets are your thing, Left offers the most customizable Home Screen experience of any habit app, with 3000+ combinations that blend habits, countdowns, and life milestones into a single view — all for a one-time price under a dollar. If you want simplicity and Apple Watch support, Streaks is the most polished, proven option on the App Store with years of refinement behind it. If you are a data nerd, HabitKit's GitHub-style contribution grids and deep analytics give you the richest view of your habit history. And if you need multi-platform sync, Habitify is your best bet — just be prepared for the subscription cost. Whichever you choose, the best habit tracker is the one you actually open every day.
