# PDF Expert vs Flight

The clearest difference is rating: PDF Expert at 4.7 against Flight's 1.0. PDF Expert also leads on monetization model (freemium vs subscription) and update cadence (fortnightly vs every 3 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PDF Expert sells 9 in-app purchases, starting at $9.99 per month and Flight sells 1 in-app purchase, starting at $1.99 per year. Whichever you choose, the download price is not the number that matters.

PDF Expert holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: PDF Expert has 217K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 45% of PDF Expert's written reviews are positive against 20% of Flight's.

PDF Expert ships an update fortnightly, Flight every 3 months. The most recent releases landed on November 12, 2026 and November 4, 2026 respectively.
