Addition & Subtraction. Solved. From the innovators who bring you Times Tables Rock Stars, comes a highly engaging platform for learning to add and subtract… NumBots! NumBots is all about every child achieving the “triple win” of understanding, recall and fluency in mental addition and subtraction, so that they move from counting to calculating. Suitable from Year 1 (UK) or Kindergarten (US) upwards. Younger players will be able to access the early stages from a mathematical point of view but will find it increasingly harder to reach the level of fluency required to make continued progress.

Verdict
The clearest difference is in-app purchases: NumBots at none against Busy Bundle's 1. NumBots also leads on update cadence (every 5 weeks vs every 49 months) and review sentiment (66% vs 40%). Busy Bundle's advantage is iOS requirement (6.0 vs 13.0). On price, ads and device support there is nothing between them.
