# Thermometer++ App vs Hello Aurora

The clearest difference is ads: Hello Aurora at none against Thermometer++ App's shown. Hello Aurora also leads on update cadence (every 9 days vs every 5 weeks) and iOS requirement (16.4 vs 18.6). Thermometer++ App's advantage is review sentiment (75% vs 45%) and ratings volume (7.3K vs 149). On price, in-app purchases, monetization model and chart position there is nothing between them.

Both are free to download. Thermometer++ App sells 3 in-app purchases, starting at $0.99 per month and Hello Aurora sells 14 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Thermometer++ App holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Thermometer++ App has 7.3K ratings behind it against 149, so its average is the more settled of the two. Written reviews point the same way: 75% of Thermometer++ App's written reviews are positive against 45% of Hello Aurora's.

Thermometer++ App ships an update every 5 weeks, Hello Aurora every 9 days. Both last shipped on November 1, 2026.
