HabitKit Vs Loop Habit Tracker: Which Fits You

Facts are from each app's Google Play listing, Loop's website, FAQ and source code, and HabitKit's own help pages, on the date at the top of this page. HabitKit's prices vary by country and are shown in the app.

This is the biggest difference in how the two apps feel.

Loop's signature is the habit score, a percentage that rises each time you do the habit and decays slowly when you don't. Its source code gives a daily habit a half-life of about 13 days, so one missed day after a long run barely dents it; Loop's FAQ says a perfect daily habit reaches 80% after a month and 99% after three. The listing makes the point directly: a few missed days after a long streak "will not completely destroy your entire progress", unlike other don't-break-the-chain apps. Each habit also has a calendar, a history chart, its best streaks and a breakdown by weekday, a tap away from the main list.

HabitKit puts the history itself on the main screen. Each habit is a grid, one tile per day, filled in the habit's colour, so you see months of every habit at once without opening anything. A missed day is one gap among the filled tiles, which makes the same point as Loop's score in a different way: the record doesn't reset. Count and Measure habits fill a day's tile partway, so 1.5 of your 2 litres looks different from a full day (how the grid works).

HabitKit's detail view, with demo data: six months of one habit on a single screen, the streak and weekly goal beneath it.

If you like a single number that sums up how established a habit is, Loop's score is a thoughtful design. If you'd rather see the days themselves, HabitKit's grid shows them without a tap.

Both apps handle yes-or-no habits and amounts. Loop's measurable habits take a unit you type and a target of "at least" or "at most" per day, week or month. HabitKit's Count habits step up one at a time and Measure habits take an amount in your own unit.

The difference is in quitting. Loop tracks positive habits only; an "at most" target can cap something, but there's no habit type for counting clean days. HabitKit has quit habits that count the days you stayed away, and a Count or Measure quit habit can set a Stay Below limit, so "fewer than two coffees" can be the goal (tracking a habit you want to quit).

Loop is more flexible with schedules: a habit can run every three days, twice a week or five times in ten days, and you can mark a day as skipped so it doesn't count against you. HabitKit sets a streak goal per day, week or month, so a weekly goal of five leaves two days off without a skip button (taking a day off). Neither app lets you pick fixed weekdays for a habit itself.

Loop gives each habit one reminder, at one time on the weekdays you choose, and its notification has buttons to log it. Recent Google Play reviews report reminders arriving late or not at all on Android 16.

HabitKit gives each habit one reminder for free and up to three with Pro, plus a free daily check-in, and on Android the notification has buttons that complete the habit without opening the app (setting a reminder).

Widgets favour Loop on price. It has six widget types, all free and resizable, each showing one habit: Checkmark, which you tap to log, plus History, Score, Streaks, Frequency and Target, which open the habit. HabitKit has three on Android, all resizable and part of Pro: one habit's grid with a button for today, or a Compact Habit List of several habits where you can tap today or an earlier day (adding a widget).

Loop is Android only. Its FAQ says plainly that there is "currently no iOS version", the iOS request on GitHub is still open, and in December 2025 the project turned down a proposal to rebuild it for iPhone in SwiftUI. If you switch to an iPhone, Loop can't come with you.

HabitKit is the same app on iPhone and Android, and an export file moves your history between them in either direction (moving to a new phone).

Loop's code is still being worked on, but its last release, 2.3.1, reached Google Play in September 2025, more than a year before the date at the top of this page. That isn't a problem for a finished app that does what you need. It's worth knowing if you rely on reminders working with each new version of Android.

Both apps keep everything on your phone and need no account.

Loop goes further than most: it doesn't even ask for internet access, and its Google Play listing says it collects and shares no data. It exports a full database backup or CSV files, imports from Loop, HabitBull, Rewire and Tickmate, and keeps a daily copy of its database in a folder that is removed if you uninstall the app. It has no sync between devices; an experimental sync was removed in 2021 with a promise to bring it back, and it hasn't returned.

HabitKit keeps seven daily backups next to your data, and on iPhone a daily backup in your own iCloud as well. Anyone can export everything to a file and import it again (export and import). It connects to the internet for purchases and backups; its App Store label lists purchases as linked to you, and some usage, diagnostics and approximate location data as not linked.

Loop is free, and always has been. There's nothing to buy, no ads, and its listing promises there never will be.

HabitKit is free for four habits with no time limit, including notes, categories, quit habits, a reminder per habit, backups and export. Pro adds unlimited habits, widgets, charts and up to three reminders per habit, as a monthly or yearly subscription or a one-time Lifetime purchase (what Pro unlocks). If you track more than four habits and want widgets, Loop is the cheaper one by the whole price of Pro.

• It's free with no limits, and open source.
• It never connects to the internet and collects no data.
• Six free widget types, and flexible schedules such as every three days.
• A skip button, and a habit score that forgives a missed day by design.
• Imports from HabitBull, Rewire and Tickmate, and translations in more than 40 languages.

• It runs on iPhone as well as Android.
• Months of every habit are visible on the main screen, not behind a tap.
• Quit habits count clean days, with a Stay Below limit for amounts.
• Up to three reminders per habit with Pro, and a daily check-in.
• Daily backups to your own iCloud on iPhone, and it's updated regularly.

There's no importer for Loop backups. You would create your habits again in HabitKit and fill in recent days from each habit's calendar (fixing a past day). If you're on Android and Loop is doing its job, there's no need to switch; if you're moving to an iPhone, HabitKit is the one that can come with you.

Is Loop Habit Tracker Available On iPhone?

No. Loop is Android only, from Google Play or F-Droid, and its FAQ says there is currently no iOS version. HabitKit runs on both.

Is Loop Habit Tracker Really Free?

Yes. It's open source under the GPLv3 licence, with no ads, no in-app purchases and no account.

What Is Loop's Habit Score?

A percentage that rises each time you do a habit and slowly decays when you don't, so a single missed day after a long run changes it very little. For a daily habit it decays with a half-life of about 13 days.

Does HabitKit Have A Habit Score?

No. HabitKit shows each habit as a grid of days, with a streak on the habit's detail page and, with Pro, completion rates on the Charts screen. Our essay on streaks and consistency explains how to read it.
