I've seen this UI in other apps, and I absolutely fucking hate it. Google Maps was a particularly egregious offender, where rotating the device or calibrating the compass would prompt for feedback, usually in the middle of trying to use a map. And who shakes a device in annoyance anyway?!

No kidding. Especially annoying when using Google Maps and driving a stick shift.

The stick shift gesture should notify the police of your location and destination.

This is so, so dumb. Who actually shakes their phone in anger? Very few people. How many people accidentally trigger things like this in the course of everyday usage? Everyone.

Google Maps has the same thing and it just strikes me as some cutesy feature a developer thought would be funny, but is actually very annoying.

Having an app developer available to be shaken in anger was deemed impractical.

Wow. I am truly impressed.

A lot of companies use the "shake the phone hard" as a way of sending feedback.

Neat!
