"If you are looking for an app that will let YOU be the master of the content it serves your child, regardless of their current abilities – then this is the one you want. I doubt you’ll find a more feature packed app for teaching number bonds in the entire App Store." @appsforhomeschooling

"Bottom Line: A slick, well-developed, and inexpensive mental math testing app."

"My little boy was told to learn numberbonds to 10 and 20 by his school. This app has really helped! Initially he was slow and finger counting, but after a few weeks his confidence with 10's and 20's is AMAZING, not a finger in sight!" - Beta tester

Great app

I downloaded this to help my son with his number binds. This app does what it says in the tin.

This app is good for generating questions however I hoped that I could set it to do specific simple addition number bonds. My child is learning his addition facts up to a grand total of 20. Currently we are learning 4 sets - addition facts for zero up to 20, addition facts for number one up to 20, addition facts for the number 2 up to 20, addition facts for number 3 up to 20. Example
0 + 1 = , 0+2= , 0+3=
This is the closest app I have found to it. Would be good for overall testing but not so much in early stages. Good how there are not loads of distracting animations. Hope developer can do a few add - ons quickly and then I'd tell everyone about it.
