Verdict
The clearest difference is update cadence: Know at every 8 days against 3D's every 5 months. Know also leads on iOS requirement (14.0 vs 17.0). 3D's advantage is ratings volume (9 vs 1). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.9 for 3D against 5.0 for Know. That said, the two scores are not equally well evidenced: 3D has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
3D ships an update every 5 months, Know every 8 days. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
