Koncentro

A recent XDA piece profiled Koncentro, a small open-source desktop toolkit that ties together a Pomodoro timer, task list, and app blocker in one window. The idea is right, but the app is Windows and Linux only. On Android, that same job splits across several tools, and the good ones do it better than a desktop app can (they can lock the phone itself). These are the seven Koncentro alternatives we recommend on Android, ranked for people who need focus, tasks, and blocking in one loop.

Why look past Koncentro on Android

Three reasons the desktop model breaks on the phone:

The 7 Koncentro alternatives on Android

1. Session (Pomodoro), best for the focus statistics reader

Session is a Pomodoro app that treats the timer as the smallest part of the product. The daily and weekly stats show streaks, distraction attempts, and category breakdowns. Session vs Koncentro in 2026: the desktop app tracks the same signals but only for the current session; Session builds up a picture across weeks.

Where it falls short: the free tier caps custom category counts. Sync across devices is a paid perk.

Pricing: free with a subscription for cross-device sync and advanced stats.

Migrating from Koncentro: rebuild the category list once; Session’s importer only reads iCal-style exports.

Download: Aptoide · Google Play

Bottom line: pick this when the data behind your focus matters as much as the focus itself.

2. Forest, best for the motivational carrot

Forest grows a virtual tree while you work; leave the app during the session and the tree dies. It sounds trivial until you notice how well it holds a teenager or a screen-happy adult on task. The paid unlock funds Trees for the Future, which plants real trees. Forest vs Koncentro in 2026: Koncentro blocks apps; Forest builds an emotional cost for opening them.

Where it falls short: it’s a one-purpose app. No task list, no reporting, no calendar.

Pricing: one-time paid app on Google Play; the iOS build is a separate purchase.

Migrating from Koncentro: there’s nothing to migrate. Set your session length, plant a tree, work.

Download: Aptoide · Google Play

Bottom line: pick this when guilt works better than an app blocker.

3. TickTick, best for the tasks-plus-timer package

TickTick is a task manager that ate a Pomodoro app. The timer sits next to the todo list, the habit tracker, and a calendar; a task and its Pomodoros live in the same object. TickTick vs Koncentro in 2026: TickTick reunites the “what am I doing” and “how long am I doing it” that Koncentro splits into panes.

Where it falls short: the free tier caps the number of habits and calendar sync frequency. Premium is where most people land.

Pricing: free with a subscription for advanced calendar sync, habit expansion, and detailed stats.

Migrating from Koncentro: export Koncentro’s task list to CSV, then paste into TickTick’s bulk import. Timer sessions do not transfer; start fresh.

Download: Aptoide · Google Play

Bottom line: pick this when the to-do list is where your attention actually starts.

4. Focus To-Do, best for the minimal timer-plus-list

Focus To-Do does the same tasks-plus-Pomodoro pairing as TickTick but with a smaller product footprint. Cross-device sync between Android, Windows, and macOS is included on the free tier, which is unusual. Focus To-Do vs Koncentro in 2026: closest structural match, plus a phone client.

Where it falls short: the design is dated compared with TickTick or Session. No integrated calendar.

Pricing: free with a subscription that unlocks statistics history and additional project slots.

Migrating from Koncentro: the app imports Todoist CSV, so re-export Koncentro tasks through Todoist and then import here.

Download: Aptoide · Google Play

Bottom line: pick this when you want Koncentro’s shape on the phone without a monthly fee.

5. Loop Habit Tracker, best for open-source habit tracking

Loop Habit Tracker doesn’t ship a Pomodoro timer, but it handles the other half of what Koncentro’s users care about: the streak. It’s fully open source, on F-Droid, no accounts, no ads, no data leaves the phone. Loop vs Koncentro in 2026: Loop is the habit dashboard Koncentro doesn’t have.

Where it falls short: no timer. Pair it with Goodtime or Session for the working half of the loop.

Pricing: free, GPLv3.

Migrating from Koncentro: create your habits by hand. Loop’s CSV importer reads its own export format only.

Download: Aptoide · Google Play · F-Droid

Bottom line: pick this when you want the streak view without a subscription or a login screen.

6. Goodtime, best for a minimalist open-source Pomodoro

Goodtime is a small, quiet Pomodoro app that respects the phone: no ads, no accounts, no telemetry. It logs sessions locally and shows a clean stats view. Goodtime vs Koncentro in 2026: Goodtime is the timer half of Koncentro, done well, on Android.

Where it falls short: no task list. No sync. If you want your Pomodoros linked to specific tasks, pair with TickTick.

Pricing: free, GPL, on F-Droid.

Migrating from Koncentro: carry the categories over by hand.

Download: Aptoide · Google Play · F-Droid

Bottom line: pick this when you want to time the work and stop there.

7. Toggl Track, best for freelancers billing by the hour

Toggl Track is a full time-tracking suite with an excellent Android app. It’s not a Pomodoro tool, but it does the deeper thing Koncentro users often actually want: reliable hours logged against projects and clients. Toggl Track vs Koncentro in 2026: Koncentro is about the current sprint; Toggl is about the invoice at month end.

Where it falls short: the free tier limits reporting depth and team features. There’s no blocker; discipline is on the user.

Pricing: free for up to five users; paid tier for reporting and integrations.

Migrating from Koncentro: export Koncentro sessions as CSV, then use Toggl’s CSV import to load them as time entries.

Download: Aptoide · Google Play

Bottom line: pick this when the timer’s purpose is a client invoice.

How to choose

FAQ

What is the best free Koncentro alternative on Android?

Focus To-Do covers the closest ground for free, with cross-device sync included. Loop Habit Tracker plus Goodtime is the fully open-source combo.

Can I sync a desktop Koncentro session to my phone?

Not directly; Koncentro has no phone client and no API. Most people run Koncentro on the laptop, and any of TickTick, Focus To-Do, or Session on the phone, and accept two silos.

Do any of these actually block apps like a real focus mode?

Digital Wellbeing does the blocking natively on Android. Session and TickTick can trigger Focus Mode via shortcuts; Forest can’t touch other apps but adds enough emotional cost that many users don’t try.

Is TickTick or Focus To-Do more like Koncentro?

Focus To-Do is structurally closer, a task list with a timer glued on. TickTick is more ambitious and includes a habit tracker and a calendar; it’s Koncentro plus the rest of a productivity suite.

Are there any open-source Koncentro alternatives on Android?

Loop Habit Tracker and Goodtime are both open-source and on F-Droid. They cover the streak and timer halves respectively.

Can I use these while offline?

Focus To-Do, Session, Loop, Goodtime, and Forest all work offline. TickTick and Toggl need a sync when they can reach the network.
