Perhaps an easy approach to implement more features is to connect the moshimeter to other apps that can do endless actions, math operations, etc. Like “Tasker” or platforms like IFTTT that can do so many actions with a single HTTP post trigger (like https://ifttt.com/maker), that would allow to easily trigger multiple actions based on the moshimeter values.

Allowing interaction with Tasker app will allow to perform math, trigger alarms, notifications, etc. And sending info to Tasker doesn’t sound that difficult, here is a link about that http://tasker.dinglisch.net/developers.html
It is a pretty powerful app.

It would be nice to have many features implemented natively in the app, but “outsourcing” the features to other specialized apps can be a quicker approach.
