Focus & Study Timer: Tsuzuroku

Build the proof that you kept going.
Log your study and work sessions one by one, and watch your effort become visible. Every time the streak graph turns greener, you'll notice the person who keeps showing up — you.
Tsuzuroku means "keep a record of continuing."

▼ Great for
・Students preparing for exams or qualifications who want to track study hours
・Anyone who wants to keep their effort as something they can see
・People who focus better with the Pomodoro technique
・Those who like to run their daily routine in a set flow
・Anyone who loves collecting proof of their progress

▼ How it works
Create a task, then just press Start. Press finish, and your session is saved automatically. Look back on when, what, and how long you worked through the calendar and timeline views. You can add or subtract time manually, so migrating your past records is easy too.

▼ Main features
◎ Three timer modes
Choose from a focus-and-break cycle, a stopwatch, or an alarm. Work and break lengths are fully adjustable, so you can build a rhythm of focus and rest that fits you — Pomodoro style, open-ended, or "focus until 5 PM."

◎ Calendar & streak graph
See your good days at a glance. The more time you put in, the deeper each day is colored, so your streak becomes proof you can feel. Look back by day, week, month, or year with bar graphs.
(Month and year views unlock with Premium.)

◎ Timeline view
A 24-hour timeline shows when, on which task, and how long you worked, all in one list. You can edit your records right here.

◎ Trophies & Color Packs
The longer you keep going, the more trophies you collect — from early milestones all the way to the endgame. At key milestones, you'll unlock Color Packs that add new background colors for your tasks. Trophy notifications can be instant, or bundled as daily, weekly, or monthly summaries — so they never break your flow.

◎ Routines
For when you want to run several tasks in a set order. Choose between two break styles — breaks between tasks, or breaks at fixed times. Rotation is supported too.

◎ Task reminders
Set a reminder for specific days and times. A quick "Time for ◯◯" nudge helps you build the habit of showing up.

◎ Notes
Jot down a free note for the day. For things you want to remember, or to look back on later.

◎ Lock Screen & Dynamic Island
Live Activity supported. Check your timer and do basic controls right from the Lock Screen.

◎ Background customization
Set a solid background from 18 traditional Japanese colors, or use your own favorite photo. Colors from unlocked Color Packs are available too.

◎ Goals
Set target times by day, week, month, or year. Hit them and a star appears on your calendar.
