Habitica.com and google calender

[omer301]

Assalamualaikum,

So recently I have discovered this website which probably very few of you know and that is Habitica.com

So this website is basically a motivating website in order to improve you're life

How it does this you may ask, well what it does is you put up tasks you want to do daily or habits you want to learn and every time you do this task you get "experience points" like in a video game, but in this case its more of like a motivation program. If you don't do an activity you lose health points and well you could say it motivates you to make up for it. Its based on the honesty system as in no one is monitoring you for doing good and bad things

So I want to use this tool or program for good uses like putting daily reminders such as prayer,reading the Holy Quran,etc,etc

So is this allowed in Islam, can I use this website to observe Islam?

Also I would like to know if using google calender to manage my day and time and to make a schedule is allowed in Islam
