We’ve enjoyed the steady flow of apps from developer Wombi over the past couple of years. Wombi Math is the latest to be released for iOS and Android.

As you may have guessed from the title, it’s all about the sums: a wall of equations and answers, with your children tasked with matching them correctly.

The app covers addition, subtraction, multiplication and division, with kids able to mix and match the different categories however they like.

Simple to use, and flexible enough to appeal to different skill levels, it’s good educational fun. Wombi Math costs £1.49 for iPhone and iPad on Apple’s App Store, and £1.85 for Android on the Google Play store.
