# CORE Thermal Sensor vs HeartsHome

The clearest difference is rating: HeartsHome at 4.2 against CORE Thermal Sensor's 2.5. CORE Thermal Sensor's advantage is update cadence (every 2 months vs every 11 months) and review sentiment (19% vs 0%). 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.

HeartsHome holds the better App Store score, 4.2 against 2.5. That said, the two scores are not equally well evidenced: CORE Thermal Sensor has 35 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 19% of CORE Thermal Sensor's written reviews are positive against 0% of HeartsHome's, so the app with the better star average is not the one people write more warmly about.

CORE Thermal Sensor ships an update every 2 months, HeartsHome every 11 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
