Mathematician and author Professor Ian Stewart, helped by Touch Press and his publisher Profile Books, has recently released a new app for iOS (suitable for use on an iPad) called Incredible Numbers. We saw this tweet:
I highly recommend Incredible Numbers, iPad app by Ian Stewart. New gold standard for interactive maths. For all. https://t.co/bI9YfUpViP

and how could we resist? We borrowed a nearby iPad, downloaded the app and had a play.
