Verdict
The clearest difference is review sentiment: Aquarium Log at 95% against Reefability's 27%. Aquarium Log also leads on rating (4.9 vs 2.9) and ratings volume (260 vs 29). Reefability's advantage is ads (none vs shown) and update cadence (every 4 days vs every 9 days). On price, in-app purchases, monetization model and device support there is nothing between them.
