Choose tables and number ranges, then run a fixed set of up to 500 problems or a timed sprint. Repeat facts that are still slow or often wrong.
iPhone and iPad
SumSprint helps children build fluency in multiplication tables, division, addition, and subtraction. Sessions are short and configurable. Parents can review results, approve practice, and manage rewards.
SumSprint is for children who need regular arithmetic practice, and for parents who want a clear picture of progress without ads, tracking, or an extra account to manage. The app works offline. English and Dutch are available; it defaults to English unless the device language is Dutch.
Requires iOS or iPadOS 17.6 or later. Made by Arthur de Rijke.
Choose tables and number ranges, then run a fixed set of up to 500 problems or a timed sprint. Repeat facts that are still slow or often wrong.
Review every answer, filter by correctness or speed, retry tricky problems, and follow charts and a skill heatmap over time.
Points are added only after a parent approves a session. Children can redeem approved points for one-time or recurring rewards.
Parents on a different iCloud account can link with a temporary, PIN-protected QR code and review results from their own device.
