Elevate – Brain Training

Free (IAPs) NEEDS iOS 11 or later

Apple’s App Of The Year in 2014, Elevate includes 35 games designed to improve brain power, including memory, maths, and verbal skills. It’s one of the slickest apps in this category. There’s a free version but the Pro version isn’t cheap – a year’s subscription is £38.99. However, there’s a 14-day trial period where you can try it out and decide if you want to cancel.
