Needs to be updated for iOS 11

I have always loved this app and intended to use it with my grandson got old enough to coo & babble but can’t use it because the developer won’t update! David Oates is a GENIUS is pioneering the navigation of the reverse speech phenomenon. However.... he’s an older Australian mate, and perhaps hasn’t thought about his app in a while. BUT....
Please update this! there is NO BETTER application out there for this type of function!

Much Cleaner.

The updated version (version 2) is much better and easier to use. Found a reversal straight away on a tv host I was watching. The only suggestion I would make is instead of lowering the pitch when slowed down, keep the pitch the same. And for those who don't read instructions, SAVE your reversals to your computer BEFORE upgrading sa they will be wiped (and click on settings once upgraded to read the T's & C's by scrolling up).

The review below is from version 1 when it was first realeased a few years ago.

(Version 1 - Downloaded the moment It was mentioned in Facebook. You need to scroll the the terms and conditions to the end so the accept button highlights, but it's worth the confusion. Used it many times already. Unreal.)

Original was much better

This update isn’t good. The original was much easier to use and didn’t distort the voice when slowing it down. If I hear anything, slowing it down now makes it impossible to make out the words because it morphs the voice instead. I found thousands of reversals on the old one because I could hear them clearly no matter the speed. Now I can’t hear anything but a deep voice. I’m extremely disappointed and frustrated. I used to love this app. I want the old one back.
