# AutoSub vs CaptionAddr

The clearest difference is update cadence: AutoSub at every 10 days against CaptionAddr's monthly. AutoSub also leads on ratings volume (37 vs 7). CaptionAddr's advantage is review sentiment (75% vs 67%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. AutoSub sells 2 in-app purchases, starting at $4.99 per 7 days and CaptionAddr sells 1 in-app purchase, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for AutoSub against 4.6 for CaptionAddr. That said, the two scores are not equally well evidenced: AutoSub has 37 ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 67% of AutoSub's written reviews are positive against 75% of CaptionAddr's.

AutoSub ships an update every 10 days, CaptionAddr monthly. The most recent releases landed on September 9, 2026 and September 17, 2026 respectively.
