# Soundiverse vs Modal Math

Soundiverse and Modal Math 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. Soundiverse sells 1 one-off in-app purchase and Modal Math sells 2 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

Soundiverse ships an update every 4 weeks, Modal Math every 5 weeks. The most recent releases landed on September 8, 2026 and June 24, 2026 respectively.
