# AquaticLog vs ReefLynk

The clearest difference is rating: ReefLynk at 5.0 against AquaticLog's 4.2. ReefLynk also leads on review sentiment (100% vs 70%) and update cadence (daily vs every 10 days). AquaticLog's advantage is ratings volume (407 vs 2). On price, ads, 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 ReefLynk sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
