# One Line 3D vs 1LINE one

The clearest difference is in-app purchases: 1LINE one at none against One Line 3D's 3. 1LINE one also leads on review sentiment (56% vs 28%). One Line 3D's advantage is ads (none vs shown) and update cadence (every 5 days vs every 3 weeks). On price, rating, monetization model and device support there is nothing between them.

Both are free to download. One Line 3D sells 3 one-off in-app purchases. 1LINE one asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for One Line 3D against 4.6 for 1LINE one. That said, the two scores are not equally well evidenced: One Line 3D has 3K ratings behind it against 279, so its average is the more settled of the two. Written reviews are what separate them: 28% of One Line 3D's written reviews are positive against 56% of 1LINE one's.

One Line 3D ships an update every 5 days, 1LINE one every 3 weeks. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
