# ERX vs DocUpdate

The clearest difference is review sentiment: DocUpdate at 61% against ERX's 0%. DocUpdate also leads on update cadence (fortnightly vs every 11 months) and ratings volume (2.8K vs 1). ERX's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ERX holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: DocUpdate has 2.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of ERX's written reviews are positive against 61% of DocUpdate's, so the app with the better star average is not the one people write more warmly about.

ERX ships an update every 11 months, DocUpdate fortnightly. The most recent releases landed on June 1, 2026 and September 26, 2026 respectively.
