# Photometrics vs StageLight

The clearest difference is rating: Photometrics at 4.3 against StageLight's 3.8. Photometrics also leads on in-app purchases (none vs 10) and device support (3 vs 1). StageLight's advantage is update cadence (every 3 weeks vs every 5 months) and review sentiment (84% vs 67%). On price, ratings volume and ads there is nothing between them.

Both are free to download. StageLight sells 10 one-off in-app purchases. Photometrics asks for nothing beyond the download.

Photometrics holds the better App Store score, 4.3 against 3.8. Both are backed by a comparable volume of ratings — 7 and 8 respectively. Written reviews complicate that: 67% of Photometrics's written reviews are positive against 84% of StageLight's, so the app with the better star average is not the one people write more warmly about.

Photometrics ships an update every 5 months, StageLight every 3 weeks. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
