Phone running slowly, charging slowly or low brightness? See if your device is overheating using Thermals. Thermals displays your device’s thermal state, as well as how many processors are active on your device and its uptime, as reported by iOS. Thermals helps troubleshoot: • Poor performance — iOS reduces processor speed and potentially disables processors temporarily when the device is hot. • Slow charging — battery charging causes a lot of heat and iOS can limit charging speed to reduce the additional heat that might make a device too hot. • Low maximum brightness — if your device screen stays dark despite being on full brightness, it could be limited by iOS due to heat. • Manufacturing defects — if not all processors are active when the device is cool and not in low power mode. Your device's thermal state is monitored regularly in the background and recorded in the app (if Background App Refresh is enabled). Open the app or tap the widget to record a data point manually. Export the raw data to file for corroboration with Screen Time, Xcode's Instruments, or other development tools. Also an independent Apple Watch app shows the thermal status, active processors and uptime, and thermal history of your watch.

Verdict

The call

The clearest difference is in-app purchases: Thermals at none against Cloud Notify's 3. Thermals also leads on ads (none vs shown) and chart position (#182 vs unranked). Cloud Notify's advantage is update cadence (monthly vs every 3 months). On price, device support and iOS requirement there is nothing between them.
