One-Time Purchase Habit Tracker Apps for iPhone (2026)

A one-time purchase app is a different kind of product than a subscription app. When you buy it, you own it. The developer doesn’t get to raise the price next year, add a paywall in front of features you already have, or shut down the service and take your data with it. You paid for software and you have software.

For habit tracking, this matters more than it might for other types of apps. You’re not buying access to a server running complex processes on your behalf. You’re buying a checklist with a good interface. That software runs entirely on your phone, and it does — if you choose apps built that way.

In 2026, the App Store has two genuine one-time purchase habit trackers worth recommending for iPhone.

Just Habits — $4.99

Just Habits is a one-time purchase with no subscription tier and no upsell after you’ve paid. The first 3 habits are free forever. Unlimited habits unlock for $4.99, once.

The tracking model uses a 16-week momentum grid instead of streak counters. Completed days show as filled squares; missed days stay empty. Nothing resets. The grid is intentionally designed to show recent momentum without preserving a permanent record of every bad week you’ve ever had — older entries scroll off the view over time.

Key features:

• Interactive home screen widgets (small and medium — tap to complete habits without opening the app)
• Lock screen widget for a single habit
• Backdate any day you forgot to log
• No account required — data syncs through your own iCloud
• CSV export at any time

No third-party analytics, no data collection, no account. Your habit data stays in iCloud and nowhere else.

The app is built for iPhone and iPad running iOS 26 or later.

Streaks — $5.99

Streaks is an Apple Design Award winner at $5.99 one-time, covering iPhone, iPad, Mac, and Apple Watch.

The widget support is excellent. The Apple Watch integration is among the best available for habit tracking. The app supports timed tasks — you can set a habit like “20 minutes of reading” and run a countdown timer from within the app.

Streaks is built entirely around maintaining an unbroken run. If you miss a day, your streak resets to zero. For users motivated by protecting a number, this is a feature. For users who find streak resets demoralizing, it’s a reason to look elsewhere.

The 24-habit limit is the other constraint to know about. Most users won’t hit it, but it’s worth knowing before you build a system around the app.

The Habitify Lifetime Option — $59.99

Habitify is primarily a subscription app ($29.88/year), but it offers a $59.99 lifetime purchase. For users who want cross-platform support (iPhone, iPad, Mac, Android, Apple Watch, web) and detailed per-habit analytics, paying once rather than annually is available.

At $59.99, it’s significantly more expensive than Just Habits or Streaks. The breakeven against the annual subscription is just over two years. For users confident they’ll use Habitify long-term and want the feature depth, it’s a legitimate option.

For most iPhone-focused users who just want to track habits cleanly, it’s more app than necessary.

What Happened to Other One-Time Habit Apps

A few apps that used to offer one-time purchases have changed models:

• Done (now Do Habits) changed ownership and adjusted its pricing structure. Verify current App Store pricing before downloading — the one-time option may or may not still be available.
• Productive shifted to subscription only.
• HabitMinder — verify current pricing, as apps in this category can change purchase models quietly.

The trend in the category has been toward subscription pricing. Just Habits and Streaks are notable exceptions, and both receive active updates.

Which to Choose

If you want no streaks and privacy-first tracking: Just Habits at $4.99.

If you want the streak mechanic and Apple ecosystem integration across iPhone, iPad, Mac, and Watch: Streaks at $5.99.

Both are genuinely good apps at prices that are, over a two-year horizon, a fraction of what any subscription app will cost. The difference is the tracking philosophy, not the quality.
