# ChatEngine vs Autera

The clearest difference is in-app purchases: Autera at none against ChatEngine's 11. Autera also leads on rating (5.0 vs 4.7). ChatEngine's advantage is ratings volume (163 vs 2) and iOS requirement (16.0 vs 26.0). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. ChatEngine sells 11 in-app purchases, starting at $7.99 per 7 days. Autera asks for nothing beyond the download.

Autera holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ChatEngine has 163 ratings behind it against 2, so its average is the more settled of the two.

ChatEngine ships an update every 3 weeks, Autera fortnightly. The most recent releases landed on October 17, 2026 and October 3, 2026 respectively.
