# Eye DPI Test vs Phone Tester

The clearest difference is in-app purchases: Eye DPI Test at none against Phone Tester's 1. Eye DPI Test also leads on ads (none vs shown) and review sentiment (67% vs 38%). Phone Tester's advantage is rating (4.3 vs 4.0) and update cadence (every 10 months vs every 25 months). On price and device support there is nothing between them.

Both are free to download. Phone Tester sells 1 one-off in-app purchase. Eye DPI Test asks for nothing beyond the download.

Phone Tester holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Phone Tester has 16 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 38% of Phone Tester'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, Phone Tester every 10 months. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
