Verdict
The clearest difference is ads: Reef Trak at none against Aquarium Tracker's shown. Reef Trak also leads on update cadence (weekly vs monthly) and ratings volume (48 vs 4). On price, rating, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Reef Trak sells 1 one-off in-app purchase and Aquarium Tracker sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
Aquarium Tracker holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Reef Trak has 48 ratings behind it against 4, so its average is the more settled of the two.
