Wandering_Traveler would you like the most honest answer that I can give you?
The amount of battery that the app uses is more on the tablet or phone than just simply using the browser which I have gotten used to anyway.
When I am using an app I only do it with my choice of an app, I tried qi app and dislike it, plus multiple other reasons including the battery one just made me give up on it.
Also first impressions usually are important I gave the app multiple tries when QI started and each try (updated) didn’t improve my opinion of it.
Tl’dr: app is shitty and it’s easier and more convenient to read on browser. My opinion!
