# ASR vs CalendarOCR

The clearest difference is in-app purchases: ASR at none against CalendarOCR's 1. CalendarOCR's advantage is ratings volume (5 vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. CalendarOCR sells 1 one-off in-app purchase. ASR asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for ASR against 5.0 for CalendarOCR. That said, the two scores are not equally well evidenced: CalendarOCR has 5 ratings behind it against 1, so its average is the more settled of the two.
