Verdict

The call

The clearest difference is rating: Scan Qr.code at 5.0 against 手机优化大师's 4.4. 手机优化大师's advantage is review sentiment (29% vs 5%) and update cadence (monthly vs every 3 months). On price, ads, in-app purchases and monetization model 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

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. 手机优化大师 sells 2 in-app purchases, starting at $9.99 per 7 days and Scan Qr.code sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Scan Qr.code holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: 手机优化大师 has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 29% of 手机优化大师's written reviews are positive against 5% of Scan Qr.code's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

手机优化大师 ships an update monthly, Scan Qr.code every 3 months. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
