# Pilot vs Aviation Calculator

The clearest difference is update cadence: Aviation Calculator at every 10 days against Pilot's every 31 months. Pilot's advantage is iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Pilot sells 1 in-app purchase, starting at $4.99 per year and Aviation Calculator sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Pilot ships an update every 31 months, Aviation Calculator every 10 days. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
