Great app I use at work to keep up with the time as Im in a field of work which doesnt allow watches. More choices of chime types would be nice but not that important to me. The ones they have are based on actual chimes from various churches and are very grandfather like which is exactly what I wanted. My only complaint or request would be to be able to set the volume limits so that the app doesnt go off too loud and scare my patients and myself. I would also like to see more choices on when the app is on or off. For example, rather than just being able to set it for 9-5 during the day I would like to specify which days exactly and what hours exactly to include mins. Ex: Sun (all day) Mon (off) Tues (8:30am - 6pm) Wed (9am-5pm) Thurs (8:45am-8pm) Fri (2pm-9:21pm) Sat (off). At least let us choose in 15 min increments (if not by the min) rather than hr marks since it can chime at 1 hr or 15 min increments. Thanks! If the volume control is added the app is 5 stars!!!
