Verdict
The clearest difference is rating: Eye4 at 4.4 against SAP HD's 2.3. Eye4 also leads on ratings volume (2K vs 4) and update cadence (monthly vs every 2 months). SAP HD's advantage is in-app purchases (none vs 16) and ads (none vs shown). On price, review sentiment, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Eye4 sells 16 one-off in-app purchases. SAP HD asks for nothing beyond the download.
Eye4 holds the better App Store score, 4.4 against 2.3. That said, the two scores are not equally well evidenced: Eye4 has 2K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 27% of Eye4's written reviews are positive against 33% of SAP HD's, so the app with the better star average is not the one people write more warmly about.
Eye4 ships an update monthly, SAP HD every 2 months. The most recent releases landed on September 25, 2026 and June 6, 2026 respectively.
