Not optimized well at all
Battery drains alarmingly fast while the app is open, which isn’t a huge issue because it’s used in my car where I always have a charger, but the main issue is that it causes my phone to overheat significantly which causes my phone to automatically lower screen brightness which while driving on a sunny day, while wearing sunglasses, means I can’t see it and picking up the phone while driving to look closely at it for directions is dangerous.
