Needs an update
Since iOS 9 came out, alarms dont consistently play the right song as you have it set. Sometimes they havent even gone off at all.
Contacting support about it just got a response of "were a small company" and it felt like my concern was getting blown off and this wouldnt be fixed, so ongoing support for 24/7 seems questionable.
