Forest App vs Focus Keeper vs Be Focused: Timer Comparisons

Why the Timer App Choice Matters

Productivity timers are a deceptively consequential piece of personal software. The timer you choose shapes how you start focused work, how you experience breaks, and how visible your progress becomes over weeks and months.

Three apps dominate the Pomodoro-style timer category in 2026: Forest, Focus Keeper, and Be Focused. Each has been downloaded millions of times. Each represents a different design philosophy.

Forest is gamified, social, and environmentally linked. Focus Keeper is minimalist and data-rich. Be Focused is flexible and task-tied. The right choice depends on what motivates you, how you prefer to track progress, and what platform you live on.

This comparison is based on the public app store data as of early 2026, the published feature sets, and practitioner experience. Features change, so verify the current version before committing.

Forest: The Gamified Timer

Forest launched in 2014 and has been downloaded more than 100 million times across iOS, Android, and Chrome extension according to its developer Seekrtech.^[5] The core mechanic: when you start a focus session, you plant a virtual tree. If you leave the app before the timer ends, the tree dies.

Complete sessions grow the tree and add it to your virtual forest.

Forest Features

• Tree-planting mechanic with visual forest growth over time.
• Dozens of tree species unlocked through focus hours.
• Real tree planting through partnership with Trees for the Future. Every few hundred virtual trees the app funds a real one.
• Whitelist mode that allows specific apps during focus (useful for reference apps, calculators).
• Friends and group focus sessions where multiple users plant trees together.
• Statistics with daily, weekly, monthly views.
• Tags for sessions (work, study, reading, exercise).
• iOS, Android, and Chrome extension versions.

Forest Pricing

Free on Android with ads and limited features. Paid on iOS (one-time purchase around $3.99). Chrome extension is free. In-app purchases for tree species and real-tree planting.

Forest Strengths

The gamification works. The visual forest growing over weeks produces a durable motivation signal that pure timers cannot. The real-tree planting partnership adds pro-social meaning. Group focus sessions are uniquely useful for study partners and remote teams.

Forest Weaknesses

The gamification can become performative. Users sometimes focus on growing the forest rather than doing the work. The phone has to be face-down and not manipulated during sessions, which does not prevent all forms of distraction. The statistics are usable but not deep.

Focus Keeper: The Minimalist Timer

Focus Keeper launched in 2012 and has been downloaded over 10 million times across iOS and Android.^[6] The design is deliberately minimal. The screen shows a timer, a progress ring, and the current session count. Nothing else.

Focus Keeper Features

• Adjustable focus interval (default 25 minutes, adjustable 5 to 60 minutes).
• Adjustable short break (default 5 minutes) and long break (default 15 minutes).
• Session counter with long break after every 4 sessions (standard Pomodoro cycle).
• Daily goal setting.
• Clean statistics showing total focused time per day, week, month, year.
• Background audio options (white noise, nature sounds) in the Pro version.
• iOS and Android.

Focus Keeper Pricing

Free version with basic features and ads. Pro version unlocks advanced statistics, background sounds, and removes ads. Pricing varies: around $1.99 per month or $19.99 per year, or a lifetime option around $39.99 depending on region.

Focus Keeper Strengths

The minimalism is the feature. Users who do not want gamification find Focus Keeper less distracting than Forest. The interval customization is better than most competitors. Statistics are clean and respect the data rather than obscuring it.

Focus Keeper Weaknesses

The free version is ad-supported, which is incongruent with a focus tool. The minimalism means no task tracking, so users who want to associate sessions with specific tasks need a separate app. No native task integration.

Be Focused: The Task-Tied Timer

Be Focused launched in 2014 by Denys Yevenko and has been downloaded over 10 million times across iOS, iPadOS, and macOS.^[7] It is the timer of choice for users who want to tie Pomodoros to specific tasks rather than to pure time.

Be Focused Features

• Task list with Pomodoro estimates per task.
• Actual vs estimated pomodoros tracked automatically.
• Detailed statistics per task, per project, per tag.
• iCloud sync across iOS, iPadOS, and macOS.
• Menubar app on Mac.
• Adjustable focus and break intervals.
• Export of session data for external analysis.
• Widgets and shortcuts integration on iOS.

Be Focused Pricing

Free version with basic timer. Be Focused Pro (paid upgrade, one-time around $4.99 on iOS or subscription on macOS) unlocks unlimited tasks, detailed statistics, and cross-device sync.

Be Focused Strengths

The task integration is the best of the three. Users who run Cirillo-accurate Pomodoro (one pomodoro equals one task unit) cannot beat this design.^[8] The Apple ecosystem integration is excellent. Statistics per task reveal estimation patterns that help users calibrate future planning.

Be Focused Weaknesses

No Android or Windows version. The feature set is less cross-platform than Forest. Not useful for users outside the Apple ecosystem. The task-tied focus can feel overengineered for casual users.

Side-by-Side Feature Comparison

The Decision Framework

Question 1: What motivates you to stick with a timer?

Visual progress and gamification: Forest. The tree mechanic produces durable motivation that pure timers cannot.

Clean data and respect for the numbers: Focus Keeper. The minimalism is the feature.

Seeing tasks finished with their Pomodoro cost: Be Focused. The task-Pomodoro link is unique to this app.

Question 2: What platforms do you use?

Android primary: Forest or Focus Keeper. Be Focused does not exist on Android.

Apple-only (iOS, iPadOS, macOS): Be Focused has the deepest ecosystem integration.

Cross-platform with Chrome: Forest has the best Chrome extension integration.

Question 3: Do you study or focus with others?

Yes, group focus is a regular pattern: Forest. Group sessions are the best-in-class feature.

No, focused work is solitary: Focus Keeper or Be Focused.

Question 4: Do you want your Pomodoros tied to tasks?

Yes, I run Cirillo-accurate Pomodoro: Be Focused. No competitor matches the task integration.

No, I just want structured intervals: Forest or Focus Keeper.

Question 5: Are you motivated by real-world impact?

Yes, the tree-planting mechanic matters: Forest.

No, pure productivity is the goal: Focus Keeper or Be Focused.

Research on Gamification and Focus Apps

Gamified productivity tools have a mixed research record. Hamari, Koivisto, and Sarsa (2014) conducted a meta-analysis of gamification studies published in the Proceedings of the 47th Hawaii International Conference on System Sciences, covering 24 empirical studies.^[1]

They found that gamification produces positive engagement effects in most contexts, but the effects depend heavily on user characteristics and task design. Gamification helps most when the underlying task is otherwise unrewarding.

Nicholson's 2015 paper in Gamification in Education and Business argues that meaningful gamification (tied to real-world outcomes) outperforms purely game-mechanical gamification (points for points' sake).^[2] Forest's real-tree planting partnership is an example of meaningful gamification.

The tree-growing mechanic alone is closer to game-mechanical.

Direct research on Pomodoro apps is limited. A 2020 study in the Journal of Applied Research in Memory and Cognition by Biwer et al.^[3]

on study app usage among university students found that app-supported Pomodoro users reported higher self-regulation than unsupported Pomodoro users, but the effect was mediated by prior self-regulation ability.

In other words, students with already-good self-regulation benefited more from the apps than students with poor self-regulation, which is the opposite of what many users hope for.

The broader attention research supports structured intervals. Mark, Iqbal, Czerwinski, and Johns (2015) at UC Irvine studied knowledge workers using focus apps and found measurable reductions in self-interruption and increased deep work duration.^[4] The app category appears to help, regardless of which specific app.

"Gamification is most effective when the game mechanics are tied to outcomes the user already cares about, rather than attempting to manufacture artificial motivation."

Use Case Recommendations

For Students

Forest for social studying and motivation. The group focus feature is uniquely useful for study partners, and the tree-growing visualization produces durable daily motivation across a semester.

For Software Engineers

Be Focused if Apple-only, Focus Keeper if cross-platform. The task-Pomodoro link in Be Focused maps well to ticket-based engineering work. Engineers who prefer minimal distraction favor Focus Keeper's clean interface.

For Writers and Creatives

Focus Keeper. The minimalism respects the fragility of creative focus. Forest's gamification can become a distraction itself.

For Knowledge Workers in GTD Systems

Be Focused. The task integration aligns with GTD's next-action discipline. Pomodoros become units of evidence for weekly review, which calibrates future estimation.

For Remote Workers

Forest, for the group focus feature that compensates for isolation. Team focus sessions across time zones produce shared accountability without shared meetings.

For Minimalists

Focus Keeper. The app is what it claims to be. No gamification, no social features, no upselling beyond the clean Pro version.

For Users Preparing for Exams

Forest or Be Focused. Forest for motivation and session logging. Be Focused for linking Pomodoros to specific study topics, which is useful when revisiting the logs to calibrate study hours per subject.

How to Switch Between Apps

Users commonly cycle between timer apps. The transition cost is low because the data rarely needs to transfer. Most users just start fresh with a new app and lose historical statistics.

If historical data matters, Be Focused exports session data to CSV. Focus Keeper Pro includes an export feature. Forest does not offer direct export, which is a meaningful weakness for data-oriented users.

Before switching, define the reason. Switching for novelty is usually a sign the underlying practice is weak, not the app. Switching because the current app is missing a feature you actually need is legitimate.

Common Failure Modes

Forest-Specific Failures

Tree theater. Users grow an elaborate forest while doing shallow work. The tree planted during two hours of email triage looks identical to the tree planted during two hours of deep thinking.

Phone-adjacent work. Forest kills the tree if you leave the app, but many distractions happen on the same device without leaving the app. The mechanic cannot detect attention drift.

Focus Keeper Failures

Ad-driven abandonment. Users of the free version are interrupted by ads during what should be focused intervals. The Pro version is required for real use, which should be budgeted from day one.

No task context. Users who want to know what they worked on last Thursday find Focus Keeper's data structure unhelpful because it tracks time, not tasks.

Be Focused Failures

Over-specification. Users who define 15 projects and 80 tasks spend more time on the task structure than doing the work. The task-tied design rewards clear thinking but punishes fussy thinking.

Apple lock-in. Users who later switch to Android lose all their data. Be Focused users should periodically export their statistics.

Frequently Asked Questions

Which app is best for ADHD?

Forest is often cited as ADHD-friendly because the visual feedback and gamification engage the reward system that ADHD brains find hard to activate. Focus Keeper is too minimal for many ADHD users because it offers no stimulation during breaks.

Be Focused works for organized ADHD users but is less useful for users who struggle with task definition.

Can I use these apps offline?

Yes, all three function fully offline. Cloud sync (Be Focused) and social features (Forest) require internet, but the core timer works without connectivity.

Do these apps drain the battery?

Minor impact. The apps run a foreground timer, which uses modest battery. Continuous use throughout a workday produces perhaps 3 to 5 percent additional battery drain.

What is the best free option?

Focus Keeper on Android is usable free with ads. Forest on Android has a free version. Focus Keeper Pro is worth the subscription if you will use the app regularly. Free alternatives outside this comparison include Pomofocus (web-based, completely free) and Pomodoro Timer Lite for Mac.

Can I use these apps for work other than knowledge work?

Yes. Artists, musicians, and writers use Pomodoro timers for practice sessions. Cooks use them for timing. Exercise routines can be structured as intervals. The apps are agnostic to the type of work.

Do any of these apps integrate with calendar apps?

Limited. Be Focused has iOS Shortcuts support, which can be rigged to calendar events. Forest and Focus Keeper do not natively integrate with calendars. Users who want calendar integration should look at tools like Session, Toggl Track, or Sunsama.

What happens if a session is interrupted by a phone call?

Forest kills the tree by default. Focus Keeper pauses automatically for phone calls in iOS. Be Focused pauses automatically. The Forest behavior is more punitive and more effective at changing habits.
