Description by Manamu Hattori(from the App Store)
Watch your daily efforts take shape. Korotto is a habit tracker where you mark each habit once a day. Each checkmark earns you a marble to add to this month's jar.
FOR YOU IF - Numbers and charts never kept you going - You want to build a few habits at your own pace - You enjoy seeing your efforts add up
HOW IT WORKS 1. Add the habits you want to build. Choose from suggestions or add your own 2. Tap today's circle when you've done a habit 3. Drop your marble into the jar
AS YOU KEEP GOING - Each habit you complete adds a marble to the jar - At the end of the month, your jar holds a record of your efforts - See your streak for each habit. Missing a day won't take away the marbles you've already earned
MARBLES THAT GROW As you keep up a habit, you gradually earn bigger marbles. When the jar is full, switch to a bigger one. Four jar sizes show how far you've come.
ONE JAR PER MONTH Each month gets its own jar. When the month ends, the jar gets a lid and goes on the shelf. Revisit past jars whenever you like. The jar is 3D. Tap it to shake it, swipe to spin it.
MAKE IT YOURS - Pick a color and a pattern for each habit - Choose which days to do each habit. Pause, resume, or end a habit without losing its history - Edit checkmarks for today and the previous 6 days - Set a daily reminder for a time you choose, or turn it off - Enjoy marble sounds and vibration, or turn them off
