Verdict

The call

The clearest difference is in-app purchases: Blue Map at none against Thermometer++ App's 3. Blue Map also leads on ads (none vs shown) and rating (5.0 vs 4.7). Thermometer++ App's advantage is ratings volume (7.2K vs 2) and chart position (#116 vs unranked). On price, review sentiment and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Blue Map holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Thermometer++ App has 7.2K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 76% of Thermometer++ App'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.

UpkeepUpdate frequency

Thermometer++ App ships an update every 5 weeks, Blue Map every 2 weeks. The most recent releases landed on September 28, 2026 and September 27, 2026 respectively.
