# Private Pilot Test Prep vs Sky

The clearest difference is ratings volume: Private Pilot Test Prep at 1.5K against Sky's 1. On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Private Pilot Test Prep sells 4 one-off in-app purchases and Sky sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Sky holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Private Pilot Test Prep has 1.5K ratings behind it against 1, so its average is the more settled of the two.
