Verdict
The clearest difference is rating: Blue Map at 5.0 against 知天气's 4.3. Blue Map also leads on update cadence (every 2 weeks vs every 2 months). 知天气's advantage is review sentiment (80% vs 71%) and iOS requirement (11.0 vs 15). On price, ratings volume, 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.
Blue Map holds the better App Store score, 5.0 against 4.3. Both are backed by a comparable volume of ratings — 3 and 2 respectively. Written reviews complicate that: 80% of 知天气's written reviews are positive against 71% of Blue Map's, so the app with the better star average is not the one people write more warmly about.
知天气 ships an update every 2 months, Blue Map every 2 weeks. The most recent releases landed on September 23, 2026 and September 27, 2026 respectively.
