# Blue Map vs AQI

The clearest difference is rating: Blue Map at 5.0 against AQI's 3.4. Blue Map also leads on review sentiment (64% vs 42%) and iOS requirement (15 vs 17.6). AQI's advantage is update cadence (weekly vs every 2 weeks) and chart position (#68 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

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 3.4. That said, the two scores are not equally well evidenced: AQI has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 64% of Blue Map's written reviews are positive against 42% of AQI's.

Blue Map ships an update every 2 weeks, AQI weekly. Both last shipped on November 6, 2026.
