# Lux Light Meter Pro vs Fish Identifier

The clearest difference is rating: Fish Identifier at 4.8 against Lux Light Meter Pro's 3.9. Fish Identifier also leads on update cadence (every 3 weeks vs every 3 months) and review sentiment (33% vs 21%). Lux Light Meter Pro's advantage is ratings volume (5.2K vs 15). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Lux Light Meter Pro sells 3 in-app purchases, starting at $1.99 per month and Fish Identifier sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Fish Identifier holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: Lux Light Meter Pro has 5.2K ratings behind it against 15, so its average is the more settled of the two.
