# Duly vs Auto

The clearest difference is rating: Auto at 5.0 against Duly's 4.2. Auto also leads on iOS requirement (15.1 vs 26.0). Duly's advantage is ratings volume (5 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Duly sells 5 one-off in-app purchases and Auto sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Auto holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Duly has 5 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.

Duly ships an update every 9 days, Auto fortnightly. The most recent releases landed on October 27, 2026 and October 17, 2026 respectively.
