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.

Mini browser for the Watch. Features of the Watch app: - Visit your favorite websites on the watch - Keyword search via popular search engines - Quick search from complications - Search or browsing history - Favorite websites - Offline website snapshots (requires the iPhone app) Features of the iPhone app: - Create website snapshot then sync to the watch for offline browsing or add as favorite P.S. Spider mini doesn't need the iPhone app to run, it works independently on the watch with WiFi or Cellular connection. However we've built an iPhone helper app (the companion app of the watch app) which you may find useful.
