Dot Timer rewards users with coins based on the amount of time they stay focused.
You earn 1 coin for every 10 minutes of focused time.
You can donate your coins by going to [Donation] > [Make a Donation] > [Set Donation Coins].
Once a certain number of donated coins has been accumulated, notebooks or planners will be donated to underprivileged students.
You can check your coin donation history under [Transaction History].
(You can view the actual donation records by going to Donation Page > My Information > Help > View Donation History.)
