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.

Features
Read full description

WebProxyTool captures and displays all network data that your device and installed apps transmit and receive. How It Works: The app creates a local on-device server and routes all outgoing HTTPS traffic through it. The app locally generates a trust certificate that should be installed and trusted to securely decrypt HTTPS traffic. When it is done, WebProxyTool captures HTTPS requests, makes dummy leaf certificates for requested domains, and acts as a man-in-the-middle proxy to read network data. Importantly, data is stored only in a local device database, ensuring user privacy, and WebProxyTool developers do not have access to it. The app works without any remote servers involved. Privacy Statement: 1. The configuration profile and trust certificate are generated and used only locally on your device. 2. The app does not collect any data about the user, the user's device, or other apps used on that device, and thus the app does not sell, use, or disclose to third parties any data for any purpose. 3. The captured HTTPS traffic never leaves your device. Terms of Service: https://webproxytool.com/terms-of-service Privacy Policy: https://webproxytool.com/privacy-policy
