About

Thermals

Monitor your device's thermal state and processor activity to diagnose performance issues. Understand why your phone might be running slowly, charging slowly, or have reduced brightness due to overheating. Export data for further analysis with other development tools.

Highlights
  • Displays device thermal state
  • Shows active processor count
  • Monitors device uptime
  • Troubleshoots performance issues
  • Helps diagnose slow charging
  • Identifies brightness limitations
  • Exports raw data for analysis

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 review sentiment: Thermals at 83% against Breadpad's 33%. Thermals also leads on rating (4.5 vs 3.9) and in-app purchases (none vs 3). Breadpad's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (166 vs 28). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Breadpad sells 3 in-app purchases, starting at $4.99 per month. Thermals asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Thermals holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: Breadpad has 166 ratings behind it against 28, so its average is the more settled of the two. Written reviews point the same way: 83% of Thermals's written reviews are positive against 33% of Breadpad's.

UpkeepUpdate frequency

Thermals ships an update every 3 months, Breadpad fortnightly. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
