時溶計

This app helps you break smartphone addiction through visualization and gamification.


[Melting Clock]
The numbers on the clock face melt away like wax as you use your smartphone. The dripping wax accumulates at the bottom of the screen, visually showing you how much time you've wasted today. This is a device to help you confront how many hours your smartphone is stealing your time.


[Crystal Acquisition]
Each minute you don't use your smartphone becomes one crystal. Bonuses are added for consecutive periods of self-restraint, and accumulated crystals evolve into gems of time. Dew, frost, ice, crystal, sapphire, amethyst, topaz, ruby, meridophyll, and finally, diamond. Your history of self-restraint will be displayed as beautiful specimens in your garden.


[Visualizing Time Thieves]
The app displays rankings of usage time by category (SNS / video / games / browser) and by app. Utilizing the Android OS UsageStatsManager, it visualizes "time thieves" on an app-by-app basis.


[Dissolution Warning]
If you exceed your usage compared to the median usage of the past 14 days, some of your accumulated crystals will melt like wax. The pain of loss will motivate you to exercise moderation tomorrow.

[Relief Mechanism]
For days when you can't help but use your phone for long periods due to travel or work, we've prepared up to three "Freeze Days" per month. These will be automatically suggested before your streak is broken.

[Concept]
Smartphone use is "time that melts away," while moderation is "time that remains as crystals." This contrasting metaphor encourages behavioral change. Within a poetic and literary worldview, your relationship with time will change.

[Achievement Badges]
Five types of achievement badges are unlocked based on your accumulated moderation time: 1 movie (5 hours), 1 overseas trip (20 hours), 1 national certification (100 hours), programmer job change line (1,000 hours), and master (10,000-hour rule). The meaning of the time you've reclaimed is visually accumulated.

[Daily Reminder]
Receive a local notification at a time of your choice reminding you to "check your usage for the day." You can turn this on/off and change the time in the settings.

[Daily Quest]
Three daily moderation missions are presented. These range from easy challenges like "Don't touch your phone for 30 minutes in the morning" and "Use social media for less than 5 minutes" to slightly more challenging ones. You can also replace the day's mission once by watching a video ad.

[Manual Input Mode]
Even without granting UsageStatsManager permissions, you can manually input usage time by category (Social Media / Video / Games / Browser) to progress with crystal acquisition and continuous usage count calculations.
