Verdict
The clearest difference is review sentiment: Polnav mobile Navigation at 79% against 地籍查詢's 29%. 地籍查詢's advantage is rating (5.0 vs 4.0). On price, ratings volume, update cadence and ads 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. Polnav mobile Navigation sells 13 in-app purchases, starting at $1.49 per year and 地籍查詢 sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
地籍查詢 holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 4 and 3 respectively. Written reviews complicate that: 79% of Polnav mobile Navigation's written reviews are positive against 29% of 地籍查詢's, so the app with the better star average is not the one people write more warmly about.
Polnav mobile Navigation ships an update every 2 weeks, 地籍查詢 every 3 weeks. The most recent releases landed on September 25, 2026 and September 6, 2026 respectively.
