Verdict

The call

The clearest difference is review sentiment: Dot Lab at 96% against 图像工具's 55%. Dot Lab also leads on update cadence (fortnightly vs every 2 months) and ratings volume (12 vs 1). 图像工具's advantage is rating (5.0 vs 4.5). On price, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Dot Lab sells 5 in-app purchases, starting at $1.99 per month and 图像工具 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

图像工具 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Dot Lab has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 96% of Dot Lab's written reviews are positive against 55% of 图像工具's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Dot Lab ships an update fortnightly, 图像工具 every 2 months. Both last shipped on October 25, 2026.
