What should I use to track my studies or should I use one???

​

I see everyone using apps to track their studies/study time and all that,I was someone who used to track my study time using forest ap 1-2 yrs back.

Now I kinda want to start tracking my studies coz I think it might give me some kind of motivation to study and it will be good for me to track it.

Do u have any ap suggestions???

What's ur experience on using such ap???
