I don't know why I can't seem to be able to adjust the hours correctly. when I updated the time to wake up at 7.30 am but the app keep displaying I'm to wake up at 6.30am...what's wrong? wasted my time keep trying to update it. This is good effort for developer to create this app but can pls fix all the issue...may seem minor but to me it's confusing and thus rendering it less useful. tq.
