# iDisplay vs DejaView

The clearest difference is rating: DejaView at 4.7 against iDisplay's 1.9. iDisplay's advantage is in-app purchases (none vs 4) and review sentiment (20% vs 0%). On price and ads there is nothing between them.

Both are free to download. DejaView sells 4 one-off in-app purchases. iDisplay asks for nothing beyond the download.

DejaView holds the better App Store score, 4.7 against 1.9. That said, the two scores are not equally well evidenced: iDisplay has 105 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 20% of iDisplay's written reviews are positive against 0% of DejaView's, so the app with the better star average is not the one people write more warmly about.

iDisplay ships an update every 6 weeks, DejaView every 4 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
