IQ boost

Don't even bother downloading this app unless you want to spend money.<br/><br/>I'm so glad I downloaded this app before version 2.0.4, because with this latest release, it has become useless due to the new limitation of having to pay to access any mode higher than 1-back. I won't ever update it unless the developer changes it back to the way it was.

Started using this yesterday and I am finding it difficult. I'm starting to learn one back but two back.....😱⁉

Progress chart in particular makes this great. It would be neat to export your progress as a CSV, but that's my only feedback.

I have bought every other N Back app. This one is my favorite, by far. I like the flexibility of offers to control the timing, in-game feedback, stimulus type, stats, etc. I love it. Just with there was a bit of a refresh on the UI to make it look a little newer, but that’s no big deal. Awesome app!

Great game, really works but needs to be updated for current iOS

iOS 7.0.4. I don't know if this app really makes you smarter or not. But it is definitely challenging. I've had this app for years but it used to allow you to play more than one game, up to 20 in settings. Now you have to hit Done and Play. This renders the Number Of Games setting useless. Other than that it's a good game. But I'm still rockin my old iphone 4 so maybe it's me that needs the update. lol

I'm hearing impaired and the update removed the option to play a visual only mode. Now I'm forced to play dual mode.

Crashes and freezes constantly with the latest iOS 8.
