For studying i love to use the Forest App. You set a timer and plant a seed then when the time is up a tree or plant you picked is done and ready to be planted. It gives you messages if you pick up your phone to put your phone down it sounds silly but it helps a lot. I think it is such a fun way to study.
I also like to “reward” myself with something i like Lorcana cards or a pedicure if I do the homework all on time for the whole month or something like that.
