“Raise your achievement level.” What would happen if you invested 365 days a year in something, even if it was just 5 minutes a day? This app helps you find the answer to this question. If you want to achieve something 'gradually, but steadily', try using the 'Leveloper'. You can see the amazing results that the steady repetition of very small habits can produce. [How to use] Make a list as specific as possible of what you're doing every day. For example, like ‘Memorize 10 foreign words’, ’30 minutes reading’. When you're done, click the check button. You can check it once a day, and each time you do it, your experience (exp) increases by 1. For a year, 365 (or 366) is the maximum, and for a month, 31 (or 28, 30) is the maximum. Each Exp will belong to a specific level. For example, from 1 to 40 experience points are level 1, 41 to 80 are level 2, and so on. When the experience points exceed a certain range, you automatically advance to the next level. (Level up) Levels range from 0 to 9 (or 99), and each level has its own unique level color. So, you can find yourself trying to see the next level color. You can experience your level up like a game. In addition, you will continue to feel the stimulus to steadiness by checking the color that fills the calendar. If you have any questions about the app, feel free to email hmapps.feedback@gmail.com. I will answer you sincerely. I hope this app will help you a lot in forming your habits.
