# Captain Nemo vs Secret Island

The clearest difference is review sentiment: Captain Nemo at 87% against Secret Island's 34%. Captain Nemo also leads on rating (4.6 vs 4.3) and ratings volume (3.6K vs 347). Secret Island's advantage is update cadence (every 3 weeks vs every 22 months) and iOS requirement (8.0 vs 13.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Captain Nemo sells 6 one-off in-app purchases and Secret Island sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Captain Nemo holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Captain Nemo has 3.6K ratings behind it against 347, so its average is the more settled of the two. Written reviews point the same way: 87% of Captain Nemo's written reviews are positive against 34% of Secret Island's.

Captain Nemo ships an update every 22 months, Secret Island every 3 weeks. The most recent releases landed on October 1, 2026 and September 29, 2026 respectively.
