The idea of "play your bell when the falling bar in your column reaches the bottom" is a fairly quick & simple substitute for sheet music if, for example, a small handbell choir doesn't read music yet, but wants to get started playing a few simple tunes right away.
Users should note that, just like traditional sheet music, this app doesn't make sounds. Rather it assumes you have real bells, or a group of people with other bell ringing apps (like the developer's own "bell solo" app) on their own handheld devices, and this app helps you know when to ring.
However, an update addressing the following would make it really useful:
•First and foremost, it NEEDS a tempo control, so that a choir can choose different speeds for each melody.
• Also of high importance, more detailed instructions inside the app, and an info icon that opens up these instructions on every view in-app. At the very least, an in-app explanation that this is not meant to make bell sounds, but to tell you when to ring, would make this app less confusing to first time users.
•It would be nice for users to easily import their own music (perhaps via MIDI or musicXML files, or perhaps a way for users to input their own tunes directly inside the app.)
