# CollectA AR vs Ocean 4D+

The clearest difference is review sentiment: Ocean 4D+ at 100% against CollectA AR's 25%. CollectA AR's advantage is rating (3.1 vs 1.0) and in-app purchases (none vs 1). On price, update cadence, ads and device support there is nothing between them.

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

CollectA AR holds the better App Store score, 3.1 against 1.0. That said, the two scores are not equally well evidenced: CollectA AR has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of CollectA AR'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.

CollectA AR ships an update every 4 months, Ocean 4D+ every 2 months. The most recent releases landed on October 21, 2026 and October 12, 2026 respectively.
