## What is RynDevice?

See your device information and check its main functions yourself. Whether you are buying or selling a used phone or investigating a change in everyday use, RynDevice helps you check one item at a time.

■ Hardware checks, from screen to sound (9)
Check the display, touch, camera, speaker, microphone, vibration, flashlight, GPS and sensors. Run a full check in order or choose individual tests, then record a pass or fail.

■ Save results and compare earlier checks
Add notes to your results and see which items changed between two records. Compare checks before and after a repair or after testing again, then share the comparison as text or a PDF.

■ No internet? Start with the connection
Check the network connection, IP assignment, DNS and HTTPS access step by step. Save diagnostic results and compare them with earlier records. This is not an internet speed test.

■ Compare charging after changing cables
Record the battery-level change for each cable over 5 or 10 minutes, then compare two results captured under similar conditions. Share the comparison as a PDF. Charging power in watts is not available on iOS.

■ Your device information in one place
View CPU, memory, storage, battery level, charging status and other device information. Follow accelerometer, gyroscope and other sensor readings on live graphs.

■ Find the information you use most
Search for an item and keep frequent checks in Favorites. Supports light and dark modes, plus English, Korean, Japanese, German and Portuguese (Brazil).

Available information and measurements vary by device and iOS version. Values that the system restricts or cannot measure are labeled accordingly. Hardware checks rely on you to verify how a function works and record the result.
