# AquaticLog vs Fish Identifier

The clearest difference is rating: AquaticLog at 4.2 against Fish Identifier's 3.6. AquaticLog also leads on ads (none vs shown) and update cadence (every 10 days vs every 3 weeks). Fish Identifier's advantage is iOS requirement (14.0 vs 18.1). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. AquaticLog sells 3 in-app purchases, starting at $4.99 per month and Fish Identifier sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AquaticLog holds the better App Store score, 4.2 against 3.6. That said, the two scores are not equally well evidenced: AquaticLog has 407 ratings behind it against 44, so its average is the more settled of the two. Written reviews point the same way: 70% of AquaticLog's written reviews are positive against 68% of Fish Identifier's.
