# Mathio vs Numvolt

Mathio and Numvolt are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Mathio sells 3 in-app purchases, starting at $12.99 per 7 days and Numvolt sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mathio ships an update every 3 days, Numvolt every 2 days. The most recent releases landed on October 6, 2026 and October 15, 2026 respectively.
