# 3DApollo vs OPAssistant

The clearest difference is rating: OPAssistant at 4.9 against 3DApollo's 3.0. OPAssistant also leads on in-app purchases (none vs 7) and ratings volume (15 vs 2). 3DApollo's advantage is update cadence (every 3 weeks vs every 6 weeks). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. 3DApollo sells 7 one-off in-app purchases. OPAssistant asks for nothing beyond the download.

OPAssistant holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: OPAssistant has 15 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of 3DApollo's written reviews are positive against 94% of OPAssistant's, so the app with the better star average is not the one people write more warmly about.

3DApollo ships an update every 3 weeks, OPAssistant every 6 weeks. The most recent releases landed on October 6, 2026 and October 5, 2026 respectively.
