# iBiome vs Ocean 4D+

The clearest difference is review sentiment: Ocean 4D+ at 100% against iBiome's 57%. Ocean 4D+ also leads on device support (3 vs 1). iBiome's advantage is rating (4.0 vs 1.0) and in-app purchases (none vs 1). On price and ads there is nothing between them.

Both are free to download. Ocean 4D+ sells 1 one-off in-app purchase. iBiome asks for nothing beyond the download.

iBiome holds the better App Store score, 4.0 against 1.0. That said, the two scores are not equally well evidenced: iBiome has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 57% of iBiome's written reviews are positive against 100% of Ocean 4D+'s, so the app with the better star average is not the one people write more warmly about.

iBiome ships an update every 9 days, Ocean 4D+ every 2 months. The most recent releases landed on October 20, 2026 and October 12, 2026 respectively.
