# On High Alert vs Air Support!

On High Alert and Air Support! 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. On High Alert sells 6 one-off in-app purchases and Air Support! sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on October 26, 2026 and November 1, 2026 respectively.
