Description by LUNA COMPANY (from Google Play)
CheckFocus is a focus timer app that helps you start your focus goals at a scheduled time and stay focused until the end.

Whether you need to study, work, read, prepare for exams, complete projects, or manage focus challenges such as ADHD, CheckFocus helps you set your own focus schedule and reduce distractions during that time.

Focus does not always happen just because we decide to focus.
A quick notification check, opening social media out of habit, or switching apps can easily break the study or work time you planned.

CheckFocus was created to help reduce those moments.
When it is time to focus, you stay with one goal and keep your focus timer running until the session is complete.

■ Scheduled focus goals

With CheckFocus, you can set your focus goals by day of the week, specific date, start time, and end time.

For example, you can create a routine to study from 7 AM to 8 AM every weekday, focus on work from 2 PM to 4 PM, or review for an exam at a specific time before test day.

CheckFocus is not just about starting a timer.
It helps you decide when to focus and follow through with your goal at the scheduled time.

■ Forced focus timer

The core feature of CheckFocus is helping you avoid distractions during your focus time.

While the timer is running, if you close the app or move it to the background for more than 2 minutes to use something else on your phone, your focus goal may be marked as failed.

This feature helps reduce phone distractions and encourages you to stay with the goal you set.

Use CheckFocus when you need to study, work, read, prepare for exams, reduce smartphone distractions, or stay committed to a scheduled focus session.

■ Solo focus mode

When you want to focus quietly by yourself, you can use Solo Focus Mode.

Set your goal, start the timer, and stay with the app until the session ends. If you keep your focus until the timer is complete, your goal can be completed successfully.

Solo Focus Mode is useful for students, freelancers, office workers, readers, and anyone who wants to build a daily focus routine.

■ Open focus rooms with users around the world

If focusing alone is difficult, join an open focus room.

In CheckFocus, multiple users can join the same room and work toward a shared focus goal. Users from around the world can participate, start at the scheduled time, and check whether others are staying focused.

No chat is needed.
Just knowing that others are focusing with you can help you stay committed and avoid giving up.

You can create or join study rooms, work rooms, morning routine rooms, reading rooms, exam preparation rooms, and project focus rooms.

■ Focus ranking and certificates

When multiple users complete a focus goal together in an open room, you can check the ranking based on the results.

The user who focused the most can reach 1st place, and a certificate can be issued to the 1st place user.

CheckFocus is designed to turn focus sessions into motivation, achievement, and consistency.

* Get distracted by their phone while studying

* Need support managing focus challenges such as ADHD
* Give up easily when studying or working alone
