# Dog Decoder vs Dog Scanner

The clearest difference is price: Dog Scanner at Free against Dog Decoder's $3.99. Dog Scanner also leads on rating (4.6 vs 3.4) and update cadence (every 3 weeks vs every 20 months). Dog Decoder's advantage is in-app purchases (none vs 3) and ads (none vs shown). On device support there is nothing between them.

Dog Scanner is free to download; Dog Decoder costs $3.99 up front. Dog Scanner sells 3 in-app purchases, starting at $1.49 per 7 days. Dog Decoder asks for nothing beyond the download.

Dog Scanner holds the better App Store score, 4.6 against 3.4. That said, the two scores are not equally well evidenced: Dog Scanner has 37K ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 67% of Dog Decoder's written reviews are positive against 43% of Dog Scanner's, so the app with the better star average is not the one people write more warmly about.

Dog Decoder ships an update every 20 months, Dog Scanner every 3 weeks. The most recent releases landed on October 11, 2026 and October 14, 2026 respectively.
