How does BanKO's High yield savings work?

I opened an account with them because I heard that they have one of the highest monthly interest at 5% p.a. I transferred 7.5k php to try it out but so far the accrued interest is only 0.83 a day for for 2 days. 0.83 x 30 = 24.9php interest after a month. But, 5% of 7.5k is 375php interest. Would my accrued interest randomly spike up during the last banking day of the month orr is what I'm seeing in the app correct?
