# DropFlight vs Spraybook

The clearest difference is rating: DropFlight at 5.0 against Spraybook's 4.3. DropFlight also leads on update cadence (every 3 weeks vs every 6 weeks). Spraybook's advantage is ratings volume (20 vs 3). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. DropFlight sells 2 in-app purchases, starting at $299.00 per year and Spraybook sells 3 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

DropFlight holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Spraybook has 20 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

DropFlight ships an update every 3 weeks, Spraybook every 6 weeks. The most recent releases landed on August 7, 2026 and September 15, 2026 respectively.
