Static server function: You can now start a local static server on your phone, supporting the creation of multiple local websites for testing. It supports WiFi, WebDAV file management, remote file downloading with decompression, direct preview of most document, video, audio, image files, and various code files on your phone. 2. Automatic injection of window.onerror code before page loading: Now, before the page loads, the application will automatically inject some code into the webpage that helps capture potential errors and print these error messages to the application's console. You can also choose to send these error reports to a backend server for further analysis and processing. 3. Show network requests when shaking the phone: When you shake your phone, the application will display the network requests made by the current page. This can help you better understand the communication between the application and the server. Additionally, you can choose to send the recorded HTTP request logs via email for further analysis. 4. jQuery-like element selector function: The application has added a feature similar to using jQuery's element selector, which means you can select and manipulate various DOM elements on the webpage more precisely, allowing for more flexible customization of page behavior and styles. 5. Code injection function: Now, you can mix HTML and JS code in the webpage being loaded. This feature supports multiple injection scenarios, meaning you can conveniently control or intercept page requests and execute custom code on the page. 6. Added dozens of code themes and code editing commands: You can easily use code auto-suggestions and customize code themes.

Verdict
The clearest difference is rating: WebDebug at 4.5 against UserAgent Switcher's 1.0. WebDebug also leads on ratings volume (23 vs 2) and chart position (#198 vs unranked). UserAgent Switcher's advantage is review sentiment (33% vs 0%) and update cadence (every 5 days vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. WebDebug sells 3 in-app purchases, starting at $0.99 per 7 days and UserAgent Switcher sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
WebDebug holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: WebDebug has 23 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of WebDebug's written reviews are positive against 33% of UserAgent Switcher's, so the app with the better star average is not the one people write more warmly about.
WebDebug ships an update every 2 months, UserAgent Switcher every 5 days. The most recent releases landed on September 24, 2026 and September 28, 2026 respectively.
