Works great! But battery drain is significant.

It does drain the battery on my 6S. I used to be able to get a full day use with the app (Ive been using it for several years). But, the latest update has significantly decreased the battery life. This app is responsible for the vast majority of battery drain reported by my iPhone, even in the "Low Power Mode."

I will probably have to disable to app until this is fixed as my phone wont make it through the day with even minor usage.

Previous review:

Beside that, I love the app. Its always on my phone. I dont have to think about muting as it does it automatically for every appointment or location where I want my phone silent.

Sometimes I forget to use the "!ring" function, and my phone doesnt ring when I wish it did. But, thats minor. I wouldnt be without this app.

I dont think theres another app like it.
