# 超解 vs Intonation Training

超解 and Intonation Training 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. 超解 sells 4 in-app purchases, starting at $2.99 per month and Intonation Training sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 12, 2026 and October 19, 2026 respectively.
