RynDevice shows you everything your iPhone can tell you about itself — clearly organized, honestly labeled, and readable offline. ■ 19 categories, every value in one place Device, System/OS, CPU, Graphics, Memory, Storage, Battery, Display, Camera, Network, Sensors, Location, Connectivity, Sound & Media, Security, Hardware features, Thermal — plus test tools and settings. ■ Live sensor graphs View readings from the accelerometer, gyroscope and other sensors in real time, with per-axis charts and full technical details. ■ 9 hardware tests Display, touch, speaker, microphone, camera, flashlight, vibration, GPS and sensors — pass/fail per test, with a shareable report. Handy when checking a used phone before buying or selling. ■ See where every value comes from Turn on “Value source” to see the exact iOS API behind each value (utsname.machine, ProcessInfo, …). Built for developers and QA. ■ Honest about limits When iOS doesn’t expose a value (serial number, IMEI, …), RynDevice says “Restricted” instead of guessing — never a made-up number. ■ Permissions only when needed Permissions are requested only on the screens that actually need them, with a clear reason — and you can decline and keep using everything else. ■ Works offline All device info and tests work without a network. ■ Light & dark, 5 languages A first-class dark mode, and full support for English, 한국어, 日本語, Deutsch and Português (Brasil). Your device data is read to be shown on screen. Exports leave the device only when you share them yourself.
