Math practice app for kids. Multiplication, division, addition, subtraction with single digit numbers. Game Motivation - after practice kids can play a round of casual game as a reward. With the points they collected by solving the tasks they can purchase virtual goodies in the Starshop. Progress Evaluation - on the progress screen you can see which tasks are difficult to solve and might need an explanation. Adaptive Tasks - number combinations which caused problems (wrong answer) will be repeated more often so your child will improve in solving these problems faster. Settings - You can setup which operations and which numbers should your child practice, so they will not spend time with things they already know well.

Verdict
The clearest difference is in-app purchases: TechSafe at none against Arithmetist's 1. Arithmetist's advantage is update cadence (every 10 days vs every 11 months). On price, ads, device support and iOS requirement there is nothing between them.
