# Read A Res vs SMD decoder

The clearest difference is rating: SMD decoder at 5.0 against Read A Res's 4.4. SMD decoder also leads on in-app purchases (none vs 1) and ads (none vs shown). Read A Res's advantage is ratings volume (33 vs 1). On price and device support there is nothing between them.

Both are free to download. Read A Res sells 1 one-off in-app purchase. SMD decoder asks for nothing beyond the download.

SMD decoder holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Read A Res has 33 ratings behind it against 1, so its average is the more settled of the two.

Read A Res ships an update every 2 months, SMD decoder every 2 days. The most recent releases landed on June 4, 2026 and June 1, 2026 respectively.
