# Lightme vs Émulsion

The clearest difference is in-app purchases: Émulsion at none against Lightme's 8. Lightme's advantage is update cadence (every 9 days vs every 2 months) and rating (4.8 vs 4.6). On price, ads and iOS requirement there is nothing between them.

Both are free to download. Lightme sells 8 in-app purchases, starting at $2.99 per month. Émulsion asks for nothing beyond the download.

Lightme holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Lightme has 101 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 75% of Lightme's written reviews are positive against 67% of Émulsion's.

Lightme ships an update every 9 days, Émulsion every 2 months. The most recent releases landed on September 27, 2026 and July 7, 2026 respectively.
