# ProLight vs Sono

ProLight and Sono both sit at 4.8 stars, but that hides the real split: 100% of Sono's written reviews are positive against 60% of ProLight's. Sono also leads on in-app purchases (none vs 5). ProLight's advantage is update cadence (monthly vs every 3 months) and ratings volume (82 vs 7). On price, rating, ads and device support there is nothing between them.

Both are free to download. ProLight sells 5 one-off in-app purchases. Sono asks for nothing beyond the download.

Sono holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ProLight has 82 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 60% of ProLight's written reviews are positive against 100% of Sono's.

ProLight ships an update monthly, Sono every 3 months. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
