I have not found anything comparable, because Little Math does cover amazingly a lot:
Quantity lessons up to 100
Numeral lessons up to 100
Counting forward and counting backward
Quantity recognition (random icon placement)
Skip counting (grid icon placement)
Random quantities and numerals (within a range)
Addition, subtraction, multiplication and division
Progression from two-step up to five-step equations
Equations with mixed operations
But for just the quantity lessons using red dots we used Babies Don't Count ( I think it is correct name..) app for iPad, when my Little One was just starting at about 5 months. It was a good one, better then using paper cards
And since you cant use LM on iPad we did it for a couple of months. But then we switched to Little Math
