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.)

Epic Redeem

At first i said it, Seems designed to not be used. Wish i had the original.
But since then i checked again and its quite terrific. Wonderfully made for those with casual interest.
Can record a talk, play it in reverse whilst doing the dishes and add insight into what was said.
Very cleverly made compared to the original.!
