The LinkPower app is a native iOS companion for the PeakDo Link-Power family of portable power stations (LP1, LP2, LP+). Built with SwiftUI and CoreBluetooth, the LinkPower app gives you live battery telemetry, DC port control, USB-C power-limit configuration, and on-device scheduling — all over Bluetooth, with zero third-party dependencies.
This is an unofficial, community-built application. It is not affiliated with, endorsed by, or supported by PeakDo Tech. Inc. Use at your own risk.

The app communicates with Link-Power devices over a custom BLE service (0x5301) with characteristics for:
- Device commands (
0x4302) - DC control, power limits, timers, restart - Battery info (
0x4303) - Real-time battery notifications - DC port status (
0x4304) - Real-time DC port notifications - USB-C port status (
0x4305) - Real-time Type-C notifications - OTA mode (
0x4301) - Device mode detection
Standard BLE services are also used: device_information (model, firmware version) and current_time (datetime sync).

Clean Minimal Light design inspired by Apple Health and Home apps:
- White cards with subtle shadows on a light grey background
- SF Pro Rounded typography for readings
- SF Symbols throughout
- Spring animations and haptic feedback
- Color-coded status indicators (green = charging, orange = discharging, pink = bypass)
