Lirum Device Info shows real‑time system activity and published device specifications using Apple’s public APIs. What you can see CPU activity and memory usage (system‑wide, approximate). Battery level & charging state (from iOS). Live sensors: accelerometer, gyroscope, magnetometer, barometer. Location readouts with accuracy and altitude (permission required). Bluetooth LE: nearby advertisement info (name/UUID/RSSI). Device specs: dimensions, weight, display resolution, wireless bands, and environmental limits, sourced from Apple’s Tech Specs for each model. What we intentionally don’t do: No diagnostics or hardware health assessments. No battery wear/voltage/cycle count and no time‑remaining estimates. No memory “optimizers” or performance‑boosting claims. Frameworks used: UIKit (UIDevice battery level/state), Foundation (ProcessInfo thermal & Low Power Mode), Core Motion, Core Location, and Core Bluetooth. Privacy: Sensor and network data are shown on‑device only. Location is used solely to display location/accuracy and is not stored or sent anywhere.
