I also used it for first time it's confusing. I am using"Focus To Do" for some time. It's also free. It's a pomodoro based app. If you want, download it from playstore and use group invite "859D2"( it's free, this is not some referral code).
@Neyawn sir, I had joined current affairs classes for mains 2021, but could not clear prelims. Brochure says I can only watch them till mains 2021, currently I am preparing my optional, no time to watch the videos. I don't want to sell them to anyone to promote piracy. I, therefore kindly request you to increase the validity of the course till mains 2022. It will be really helpful for many students. Thank you.
