Loop details reflect the official uhabits project (github.com/iSoron/uhabits and loophabits.org) as of September 2026. If you are on iPhone, you can try Productify free and judge the overlap yourself.

What Loop users will recognise in Productify

Loop earned its reputation by refusing to do the annoying things habit apps usually do: no ads, no account walls, no nagging. Productify was built around a similar temperament, which is why it tends to be the recommendation Loop users hear most often on iOS.

The overlap is real. Productify's core is free with no time limit and no account to create: you can download it and log your first habit within a minute, just like installing Loop from F-Droid. The design is deliberately calm and minimal, closer to Loop's quiet utility than to the gamified, confetti-heavy apps that dominate the App Store. And the philosophy around data is similar in spirit: your history is treated as information for you, not as leverage against you. Missing a day resets your current streak count but never erases your record, which echoes how Loop's habit strength score treats consistency as something you build rather than something you can lose overnight.

You also keep the practical basics: smart per-habit reminders, iPhone widgets, and clear progress views, plus measurable goals for habits like steps, minutes of reading, glasses of water, or reps.

What is genuinely different

Honesty matters in a page like this, so here are the differences that might bother a Loop purist. Productify is closed source. Loop is GPLv3, and anyone can read, audit, or fork its code; if open source is a hard requirement for you, no mainstream iOS habit tracker currently clears that bar. Loop is also radically local: it needs no internet connection at all, and its README states plainly that your data is never sent to anyone. Productify likewise requires no account for solo tracking, but it is a commercial App Store app, and its optional Habit Duo feature by definition shares progress with the one friend you pair with.

The other difference runs in Productify's favour: it does more, if you want it to. Habit Duo lets you track one shared habit with one friend in a private, side-by-side view, and the TempO AI Habit Analyser reads your history to surface patterns Loop's charts leave you to spot yourself. Both are Pro features and both are strictly optional: the free core never pushes you toward them. Think of them as additions layered on a Loop-like foundation, not replacements for it.

The short version: Loop optimises for software freedom and total data locality. Productify optimises for the iPhone experience, with a free, calm core plus optional social and AI layers. Which trade-off is right depends on which phone is in your pocket. If it is an iPhone, the free download is the fastest way to test the fit.

Switching from Loop: what to expect

There is no direct import from Loop into Productify, so the honest advice is: before you retire your Android phone, use Loop's export (CSV or SQLite) to keep a permanent archive of your history. That data is yours, and it is worth saving even if no app ever reads it again.

Rebuilding in Productify is quicker than most switchers expect. The 50+ habit templates cover the usual suspects (exercise, reading, water, meditation, sleep), so recreating a typical Loop habit list takes a few minutes, not an evening. Set your reminder times, add measurable targets where Loop only offered a checkmark, and add a widget to your Home Screen so tracking stays one glance away, the way Loop's widgets kept it.

Expect the first week to feel slightly different: streak counts start from zero, and Productify shows a current streak and personal best rather than Loop's strength percentage. Your consistency did not reset, only the counter did, and the app is deliberately designed never to guilt you about it. Most people are back in rhythm within days. Start free, rebuild your top three habits first, and add the rest as they come up.

Pricing: free core, optional Pro

Loop is completely free forever, with no purchases of any kind. Productify's free plan has no time limit and includes up to 5 habits, streaks, reminders and 5 starter templates, with no account required. Productify Pro unlocks unlimited habits, all templates, custom habit units, Habit Duo and the AI Habit Analyser. The US App Store listing showed Monthly Premium at $4.99 and Yearly Premium at $19.99 when checked September 20, 2026; prices and eligible offers vary. If you only use the free tier, you can download Productify free without paying.

Which one should you choose?

If you are on Android, choose Loop, sincerely. It is free, open source, private, and one of the best pieces of software in its category. But Loop does not exist on iPhone, and waiting for an iOS version is not a plan. If you have switched to iPhone and want the closest match to what made Loop good (a free core, no account, calm design, respect for your data), Productify is built for exactly that, and adds optional extras Loop never had.

The practical move: export your Loop history for safekeeping, then install Productify free and rebuild your top habits from templates. Ten minutes, and you are tracking again.

FAQ

Common questions

No. Loop Habit Tracker (also known as uhabits) is an Android app distributed through Google Play and F-Droid, and there is no official iOS version. Apps with similar names on the App Store come from other developers and are not connected to the open source Loop project. If you have moved to iPhone, you will need a different habit tracker, and Productify is a free option built specifically for iOS.

It depends on what you liked about Loop. If it was the free core, the calm design, and the focus on your own data, Productify is one of the closest matches on iOS: free to download, no account required, guilt-free streaks, and measurable goals. It is rated 4.5 stars from 500+ App Store ratings and works on iPhone and Apple Watch.

Productify is free to download and the core habit tracking features cost nothing, with no account required. It is not open source, however. Development is funded by an optional Pro subscription (Habit Duo and the TempO AI Habit Analyser) instead of ads. If open source is a hard requirement, no iOS habit tracker currently matches Loop on that point.

There is no direct import. Loop can export your history to CSV or SQLite, which is worth doing as a personal archive before you switch. In Productify, most people rebuild their habit list in a few minutes using the 50+ ready-made templates, then carry on tracking from day one on iPhone.
