# Dot3D vs ImageSpace

The clearest difference is rating: Dot3D at 4.7 against ImageSpace's 4.0. Dot3D also leads on review sentiment (81% vs 57%) and ratings volume (96 vs 11). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Dot3D sells 2 in-app purchases, starting at $49.99 per month and ImageSpace sells 3 in-app purchases, starting at $39.99 per month. Whichever you choose, the download price is not the number that matters.

Dot3D holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Dot3D has 96 ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 81% of Dot3D's written reviews are positive against 57% of ImageSpace's.

Dot3D ships an update every 3 weeks, ImageSpace every 11 days. The most recent releases landed on September 24, 2026 and August 31, 2026 respectively.
