content: Good but needs simple improvement  It should really have more ringtone and a light notification options for when the time is up. I dont want to that horrible alarm sound or have my phone vibrate after every study session in order to know when to take a break. If you dont add more sounds please give us the option to create customized soundsringtones. Also for the S9 it is unable to make a noise in silent mode even when I give the app exception permissions.
