Review momentum
20/100
faster than 0% of Health & Fitness apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Crystal HourGlass
Like an hourglass, it is an application that makes you feel the time quietly.
There is a simple timer function.
The animation and background image relieve tired mind.
You can set the timer in seconds from 1 second to 24 hours.
During breaks of work or study,
When I got tired a while between game applications,
See at the screen and let's rest your nerves.
You can choose from 11 types of animation.
When floating, the rainbow-colored crystal that sinks to the water surface,
Glitter and flowing stardust,
Clouds appearing on the surface of a mirror like a mirror,
Bubbles disappearing into the sky softly ...
If you look at them quietly, you will gradually feel relaxed.
Cloud animation can adjust the speed.
You can choose from a variety of backgrounds.
The images on the background images "Lake shore village ", "Cherry blossom view", "Time Variation", and "Crystal Forest" change depending on the time at that time.
When you press the “Crystal Forest” button, a popup will appear and you can optionally select a different color version of the image.
Tap the part of the clock to change the color of the text.
Please enable notifications in your iPhone settings before using the app's timer function.
Please use it when you like "I want to take a ten-minute break".
I get sleepy when I see this app.
