# Reality OBJ vs 3dMaster

The clearest difference is rating: 3dMaster at 5.0 against Reality OBJ's 4.2. 3dMaster also leads on iOS requirement (15.0 vs 17.0). Reality OBJ's advantage is ads (none vs shown) and update cadence (weekly vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Reality OBJ sells 4 in-app purchases, starting at $2.99 per 7 days and 3dMaster sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

3dMaster holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Reality OBJ has 5 ratings behind it against 1, so its average is the more settled of the two.

Reality OBJ ships an update weekly, 3dMaster every 2 months. The most recent releases landed on September 23, 2026 and September 13, 2026 respectively.
