Very good so far; could even be much better!?

This is the first time Ive ever written a review. Since the developers asked but I only am because Ive just used this all for literally a minute or 2; and it does what it says. I expected it to be more complicated; and maybe be kinda fake or a gimmick. But it is quite clear already that it does what it says.
I do have many suggestions/questions though. For example, down a short hallway into a bedroom with 2 people talking occasionally. Also having a tv on, makes it quite hard to hear people speaking; as youd imagine. There are these equalizers on the app which Im going to play with more, but maybe instead of frequencies; or in addition to, you could maybe label them with what their Benefit may be. Example being if you are wanting to hear 2 people talking and there is another noise; maybe there is a way to set the equalizers to better hear the people. I understand its frequencies; and it goes from high to low. But with there being so many options and an infinite different number of possible settings......... I just find myself wishing that I better understood the entire concept etc. Im sure many others would have this issue(I promise Im not as stupid as Im appearing!)and if there is anything you can do to help me figure out how to set it to best meet my needs at any given time Id appreciate it.
Bottom line is that.... THIS APP WORKS! Its free! Although I guess theres ads, I dont recall where they were, and as far as I know they dont effect using this app. So..... a big and genuine THANK YOU, to whomever made this. Its funny, I dont see anything even claiming to do the same thing! Very strange! Anyway, great job, and you should definitely look into anything you can do to make it even better! Id suggest having it compatible with a microphone that could be purchased separately..... or even creating one specifically for these purposes! Imagine if apple had accessories like that and an app like this! Theyd of course make billions on it. All under the assumption that it would be even better! Anyway, just something to think about! Thanks again!
