Verdict
The clearest difference is rating: Check My Device at 4.5 against Eye DPI Test's 4.0. Check My Device also leads on update cadence (every 3 months vs every 25 months) and ratings volume (94 vs 2). Eye DPI Test's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support 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. Check My Device sells 3 in-app purchases, starting at $0.99 per 7 days. Eye DPI Test asks for nothing beyond the download.
Check My Device holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Check My Device has 94 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Eye DPI Test's written reviews are positive against 47% of Check My Device's, so the app with the better star average is not the one people write more warmly about.
Eye DPI Test ships an update every 25 months, Check My Device every 3 months. The most recent releases landed on October 7, 2026 and October 21, 2026 respectively.
