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.

Unlike the majority of system-based HTTP proxy capture software, Hodor is a packet capture tool based on the IP layer protocol. Consequently, Hodor is capable of capturing HTTP data traffic that many other capture software cannot, including the data traffic from Flutter apps. Hodor provides many useful features, including: - Packet capturing & rewriting with support for HTTP, TCP, UDP, and WebSocket data protocols. - Capturing and rewriting Flutter app traffic. - Support JavaScript extensions - HTTPS decryption to view decrypted data. - Mapping (i.e., replacing) data in HTTP requests and responses. - HTTP replaying and simulating requests and responses for server debugging without using the client again. - Formatting preview for Protobuf, Form-Data, JSON, HTML, JavaScript, and CSS. - Forwarding HTTP requests to other network tools within the local network for data processing (including traffic from Flutter apps). - Domain filtering to only view requests and responses from specific domains. - URL Scheme support for controlling the start and stop of packet capturing with commands. Hodor is an incredibly useful web debugging tool that can help you easily resolve various issues, making your work more efficient and enjoyable. Whether you are a developer or a tester, you can benefit from Hodor. Give it a try now! Automatic Subscription Service Rules 1. If you subscribe to the automatic renewal service through your Apple ID and do not actively cancel the automatic subscription service during the subscription period, Hodor will automatically deduct the next subscription fee from the balance of the Apple ID account linked to the automatic renewal service 24 hours before the current subscription period expires (subject to the actual Apple billing rules). You should pay attention to the balance and payment status of the account. If the renewal fails due to account issues or insufficient balance, you will bear the risk and/or loss by yourself. For your convenience, Apple will notify you of the upcoming deduction before processing the payment. It is important to note that based on the nature of the automatic renewal service, if you do not explicitly cancel the automatic renewal service during the subscription period, Apple will issue a deduction instruction to the relevant parties based on your permission. Generally, any fees deducted based on this instruction will not be refunded. 2. Hodor Pro Subscription Period: 1 year. 3. Hodor reserves the right to adjust service prices or stop providing automatic renewal services. If you do not agree with the adjusted service price, you can cancel the automatic renewal service according to these rules. If you do not cancel the automatic renewal service, the subsequent fees deducted by Apple will be adjusted to the new service fee. 4. The method to cancel the automatic subscription service is as follows: open the Apple iOS device "App Store" -> click on the Apple account profile picture in the upper-right corner -> enter "Account" -> click on "Subscriptions" -> select "Hodor" -> cancel the subscription. 5. Hodor may stop providing you with automatic renewal services according to operational needs. Your Hodor service period will end on the date of the expiry of the current service cycle. * Privacy Policy https://ximlu.github.io/hodor/privacy_en.html * Terms of Service https://ximlu.github.io/hodor/terms_en.html

Verdict
The clearest difference is in-app purchases: Thermals at none against Hodor's 11. Thermals also leads on rating (4.5 vs 4.3) and chart position (#161 vs unranked). Hodor's advantage is update cadence (every 3 weeks vs every 3 months) and iOS requirement (15.0 vs 18.6). On price, ratings volume, ads and device support there is nothing between them.
