# IDO Studio vs TSA

IDO Studio and TSA 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.

IDO Studio ships an update every 4 months, TSA every 3 months. The most recent releases landed on September 16, 2026 and September 9, 2026 respectively.
