Does anyone have experience with the Tonaly App?

Anyone here have experience with the Tonaly App? If so, worth the price to download?

Can’t find a good free app like this one that doesn’t have a pay wall for its most useful features.

I don’t have it but from what I can see it’s pretty much worth the cost if your not able to do it yourself, it’s not expensive even with the add ons for what it can do but you must learn thoroughly how to make use of all of its features to get the best out of it.
