Verdict
The clearest difference is ads: Calculator at none against 千米神眼's shown. Calculator also leads on review sentiment (71% vs 39%) and ratings volume (1.9K vs 1). 千米神眼's advantage is rating (5.0 vs 4.8) and update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, 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. 千米神眼 sells 10 one-off in-app purchases and Calculator sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
千米神眼 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Calculator has 1.9K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 39% of 千米神眼's written reviews are positive against 71% of Calculator's, so the app with the better star average is not the one people write more warmly about.
千米神眼 ships an update every 3 weeks, Calculator every 2 months. The most recent releases landed on November 7, 2026 and November 11, 2026 respectively.
