The goal of a calendar app is to remind people when they have a appointment coming up.
Since i always have my phone on vibrate, i mis al my calendar notifications.

It makes the app useless.

So what if this simple select button is added in the settings:
1) Ability to choose what Android audio chanel you use. Like in the flitsmeister app.

2) You can select to use media audio chanel. Audio is played as if it is normal media.
When phone is set to vibrate no sound plays.

You can select to use the alarm audio canel.
Audio is played as if it is an clock alarm.
Notifications sound even when the phone is set to vibrate.

Again...
It works fine in the FlitsMeister app.
I never mis a speedcam notification again.
