Who Streak is for#

Individuals tracking habits privately on one device

Streak is built for one person on one device. Log habits with one tap, track streaks via the year-view activity grid, and run Pomodoro sessions for habits that need focused time. All data stays local; no account is required and no server is involved.

Skip if:

You track habits on multiple devices and need changes to sync automatically. Streak has no sync server; moving history to a second device requires exporting a backup file and importing it manually.

Android users who keep app permissions minimal

On Android, Streak does not request the internet permission at all, making it a natural fit for users who review app permissions carefully. Installation is available from F-Droid and IzzyOnDroid without a Google Play account.

Skip if:

You rely on Google Fit or Apple Health integration for habit data. Streak logs to its own local storage only and has no health platform sync.

People switching from Loop, HabitKit, Habitica, or HabitBull

Streak imports exports from Loop Habit Tracker, HabitKit, Habitica, and HabitBull, preserving past history and streaks. Three visual themes (Classic, Minimal, Express) and configurable accent colors cover a range of aesthetic preferences.

Skip if:

Your history is in Habitify or Productive specifically. Streak's documented import list covers Loop, HabitKit, Habitica, and HabitBull; Habitify and Productive are not in it.

F-Droid users on Android

Streak is listed on F-Droid and IzzyOnDroid with automatic update tracking. Users who prefer FOSS app stores can install and maintain the app without direct GitHub interaction or manual APK sideloading.

Skip if:

You need Google Play Store availability for work MDM policy or compliance reasons. Streak is not on Google Play.

the problem

The problem it solves#

Habit tracking apps ask for more than they give. Most charge a monthly subscription to unlock basic statistics, cloud sync, or more than a handful of habits. You create an account, share your data with their servers, and accept recurring billing to keep using what you already set up.

For privacy-conscious users, the problem runs deeper. Every tap you record reflects your health routines, sleep patterns, and productivity habits. Most trackers have no self-hosted path and no offline mode. If the service shuts down or raises prices, your history goes with it.

how Streak solves it

How it solves it#

One-tap logging from list, widget, or notification

Mark a habit from the main list, a home-screen widget, or directly from the notification. Three home-screen widget types display habit progress, today's schedule, or an activity grid; each can be updated without opening the app. Widgets support custom colors, photos, opacity, and border styling.

Three habit types with flexible schedules

Track binary habits (done or not), avoid habits with relapse counting, and amount habits where you set a unit and daily goal such as pages read or glasses of water. Schedules run daily, X times per week or month, on chosen weekdays, or every N days. Fill in past days by tapping any date.

Year-view activity grid and streak statistics

A GitHub-style grid shows the full year at a glance. Per-habit statistics include current and best streaks, completion rate, a strength score, and a streak evolution chart over time. A shareable progress card exports as a polished image in several sizes.

Pomodoro focus timer with ambient sound

A timer ties to a habit and counts its session minutes toward the daily goal. Runs Pomodoro rounds with short breaks or a single long stretch. Three clock styles (Circle, Flip, Dots), built-in ambient sounds (rain, brown noise, fire), and custom audio tracks are all supported.

Import from Loop, HabitKit, Habitica, and HabitBull

Reads exports from Loop Habit Tracker, HabitKit, Habitica, and HabitBull with history and streaks preserved. Any CSV file with a habit column and a date column also works as a fallback. Backup and restore use a single file you keep; automatic backups run daily or weekly to a folder of your choosing.

Three visual themes and configurable home-screen widgets

Classic, Minimal, and Express each use different typography, shapes, and motion. Accent color, app background (solid, gradient, dots, OLED true-black, or a custom photo), launcher icon, cover photos per habit, and a profile photo are all configurable.

Strengths and trade-offs#

Strengths

No internet permission on AndroidOn Android, Streak does not request the internet permission at all. The README describes this as a core rule, not a setting. Your habits cannot be sent to any server because there is no network pathway. Apps with optional offline modes typically still include analytics SDKs; Streak has no such component.
No paid tier, no ads, no accountEvery feature is available from day one with no upgrade prompts, no in-app purchases, and no account to create. Compared to Habitify and Productive, which restrict analytics or unlimited habits to paid subscribers, Streak gives complete access without a subscription.
Import from four popular habit trackersStreak reads exports from Loop Habit Tracker, HabitKit, Habitica, and HabitBull with history and streaks intact. Any CSV with a habit column and a date column works as a fallback. Switching to a privacy-first app does not require starting your tracking history from zero.
Active development with GPL-3.0 licenseThe repository was created in June 2026 and last pushed October 14, 2026, with 42 open issues showing active community engagement. The GPL-3.0 license (with an attribution requirement under section 7(b)) lets anyone inspect, modify, or run the app without restriction on personal use.

Trade-offs

-No automatic cross-device syncStreak has no sync server. Moving habits to a second device means exporting a backup file and copying it manually. The README states directly: if you want your habits on two devices, sync that folder yourself. There is no automatic iCloud, Google Drive, or WebDAV sync built in.
-No iOS or macOS support yetAndroid, Windows, and Linux are fully supported. iOS is listed as in progress and macOS as planned in the README, but neither has a release available yet. Users on iPhone or Mac cannot use Streak currently.
-Linux build is new with rough edgesThe README notes the Linux build has only just landed and warns to expect some rough edges. Reminders only ring while the app is open on Linux. Users relying on Linux for daily habit tracking should check the GitHub issue tracker before committing to it.

versus alternatives

Streak vs alternatives#

Streak vs Habitify

Habitify is a cross-platform habit tracker with cloud sync and a freemium model. Both tools cover personal habit tracking, streak visualization, and reminders, but they diverge on where data lives and what it costs.

Feature	Streak	Habitify
License	GPL-3.0	Proprietary
Data storage	On-device only	Cloud-synced
Internet access	None requested on Android	Required
Price	Free, no tier	Free tier; premium subscription
Platforms	Android, Windows, Linux	iOS, Android, macOS, Windows

Streak gives the full feature set with no account and no subscription. Habitify's strength is cross-device sync and its iOS app, which Streak does not yet have. If you use Apple hardware or need habits to update automatically across multiple devices, Habitify's paid tier addresses that. For offline-first tracking with no network exposure and no ongoing subscription, Streak is the better fit.

Streak vs Productive

Productive is an iOS-first habit tracker with a subscription model and planning views. Streak has no iOS release yet, so this comparison is most relevant for Android users choosing between the two.

Feature	Streak	Productive
License	GPL-3.0	Proprietary
Offline	Fully offline by design	Account required
Price	Free	Monthly subscription
Platforms	Android, Windows, Linux	iOS, Android
Data import	Loop, HabitKit, Habitica, HabitBull	Not documented

Productive charges a monthly subscription for its full feature set. Streak offers comparable tracking features including habit types, reminders, statistics, and a focus timer at no cost. The primary trade is iOS availability and cloud-managed backups. For Android users who want private, offline tracking without a recurring payment, Streak is the clear choice.

frequently asked

FAQ#

Does Streak sync habits across devices?

No. Streak stores data locally and has no sync server. To move your habits to a second device, export a backup file and import it on the other device. The README suggests syncing your backup folder via a cloud drive app you set up yourself as a manual workaround.

Is Streak available on iPhone or Mac?

Not yet. iOS support is listed as in progress and macOS as planned in the README, but neither platform has a release. Android, Windows, and Linux are fully supported as of version 2.3.0.

Where can I download Streak on Android?

F-Droid is the recommended path: it installs the app and keeps it updated automatically. IzzyOnDroid and OpenAPK are also supported. Direct APK files for each phone architecture are on the GitHub Releases page. Streak is not on Google Play.

Can I import my history from another habit tracker?

Yes. Streak reads exports from Loop Habit Tracker, HabitKit, Habitica, and HabitBull, preserving your past history and streaks. Any CSV file with a habit column and a date column also works as a general fallback.

What license does Streak use and can I use it commercially?

Streak is released under the GNU GPL v3 with an additional attribution requirement permitted by GPL-3.0 section 7(b). You can run, modify, and distribute the app freely for personal use. The GPL-3.0 requires distributing source code for any modified version you share publicly. The attribution term requires preserving the original author credits in modified versions.
