Ratings & Reviews performance provides an overview of what users think of your app. Here are the key metrics to help you identify how your app is rated by users and how successful is your review management strategy.
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.
