How many alarms can you set on Android?
Is it possible to have more than ten (alarms)? Maybe not with HTC clock, but yes it is possible. As mentioned by dotVezz in the comment, "it's definitely not a constraint of the OS". Android doesn't set any restrictions regarding how many alarms they can store/handle, even on per-app basis.
