### 5/5 — Utterly amazing

*2020-04-24*

This app is SO easy to use and so amazingly helpful. Often there are basic needs that Apple ignores/forgets. (“You vill do it OUR vay.”)

Not only does Corr fill those needs, but does it the best. AND has more features than Apple would have done. 

Thanks for an amazing problem solver!

For extra credit; maybe a name better than “Corr” would get more hits.

PS: Thank you SO much for publishing an actual change log, not like lazy developers who write “we fixed stuff” and leave us guessing what’s new. Thank you, thank you!!!  😉👍🏻
