# Ninoa vs Trigger

Ninoa and Trigger 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. Ninoa sells 4 in-app purchases, starting at $7.99 per month and Trigger sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Ninoa ships an update fortnightly, Trigger weekly. The most recent releases landed on October 3, 2026 and October 24, 2026 respectively.
