# Stavix vs SDJ

The clearest difference is review sentiment: Stavix at 100% against SDJ's 11%. SDJ's advantage is in-app purchases (none vs 13) and rating (3.4 vs 3.0). On price, ads and device support there is nothing between them.

Both are free to download. Stavix sells 13 one-off in-app purchases. SDJ asks for nothing beyond the download.

SDJ holds the better App Store score, 3.4 against 3.0. That said, the two scores are not equally well evidenced: SDJ has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Stavix's written reviews are positive against 11% of SDJ's, so the app with the better star average is not the one people write more warmly about.

Stavix ships an update monthly, SDJ fortnightly. The most recent releases landed on September 18, 2026 and September 6, 2026 respectively.
