About this app

■ A Radar-Style Study Timer That Visualizes Your Efforts

Shojinkei (Study Timer) is a learning timer app that records the time you spend on things you want to continue, such as studying, exercising, and reading, and visualizes it with a retro submarine sonar-style radar and graphs. It's not just a stopwatch that measures time. The effort you accumulate grows in a visible form on the screen.

You can instantly see "how much you concentrated today" and "how many hours you've accumulated this week" the moment you open the app. The feeling of your efforts being rewarded will motivate you to take another step tomorrow.

■ The Enemy on the Radar Disappears as You Study

The main screen of Shojinkei is a circular radar that glows green. When you start recording, your ship launches and moves towards the targets (enemies) that spread across the screen, disappearing as you touch them. After 25 minutes of focused work, the screen approaches clear, and after a 5-minute break, you move on to a new phase. Experience the Pomodoro Technique's "25 minutes of focused work + 5 minutes of rest" rhythm in a game-like format.

The sweep rotation speed is designed for a relaxed tempo (approximately 10 seconds per rotation), ideal for concentration. Simply watching it helps regulate your breathing and naturally puts you into work mode—it's more than just "measuring"—it's a mechanism that makes you want to keep working.

■ All time settings are based on scientific evidence

The values ​​in the concentration tracker are not determined "arbitrarily." They are designed based on insights from psychology, behavioral science, and physiology.

• 25 minutes of concentration + 5 minutes of rest: Repeating short periods of concentration and short breaks prevents a decline in attention (Pomodoro Technique / Research on the effectiveness of micro-rests, Ariga & Lleras, 2011, etc.).

• Radar sweep: Approximately 10 seconds per cycle (0.1Hz): The frequency of "resonant breathing" that regulates heart rate variability and promotes calmness. The sweep acts as an unconscious breathing pacer (Lehrer & Gevirtz, 2014).

• The device moves slowly: Sudden movements and flashing distract attention, so it is deliberately kept slow. Designed to avoid distractions (Yantis & Jonides, 1984).

* Increases your progress every 15 minutes: Breaks down effort into small sub-goals and visualizes progress (Goal Gradient Effect/Law of Progress).

* Continuous Recording (Streak): The desire to avoid interruptions and repetition encourage habit formation (Habit Formation Research: Lally et al., 2010).

* Visualization of Progress: The more you record and check your progress toward your goal, the higher your achievement rate (Meta-analysis: Harkin et al., 2016).

This app is designed with "persistence" in mind, based on scientific principles.
