Verdict
The clearest difference is rating: IDExpert at 4.0 against 台灣自來水's 1.3. IDExpert also leads on iOS requirement (10.0 vs 12.0). 台灣自來水's advantage is update cadence (every 2 weeks vs every 5 weeks) and ratings volume (4 vs 1). On price, review sentiment, ads and in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
IDExpert holds the better App Store score, 4.0 against 1.3. Both are backed by a comparable volume of ratings — 1 and 4 respectively. Written reviews complicate that: 11% of IDExpert's written reviews are positive against 13% of 台灣自來水's, so the app with the better star average is not the one people write more warmly about.
IDExpert ships an update every 5 weeks, 台灣自來水 every 2 weeks. The most recent releases landed on October 14, 2026 and October 24, 2026 respectively.
