## What is Kelvarune?

Kelvarune is a developer tool that lets you monitor, debug, and control ESP32 / Arduino and other embedded devices from your smartphone in real time.

Add just a few lines of the Kelvarune SDK to your sketch, and your Dashboard builds itself automatically. No complex setup - connect over BLE or Wi-Fi/WebSocket and you're ready to go.

■ Monitor
- System Metrics such as CPU, free heap, and connection status, shown automatically
- Add User Metrics like temperature, humidity, RPM, or voltage with a few lines of code
- Clear display styles: Number, Gauge, Bar, LED, and line graphs

■ Debug
- Filter, search, and copy DEBUG / INFO / WARN / ERROR logs in Console
- Track connection changes, reboots, and other key state changes in a timeline with Events
- View current value, min, max, average, and a history graph in Metric detail

■ Control
- Command UI is generated automatically from your SDK-side definitions (Button, numeric, Boolean, Enum, and more)
- Commands that trigger real actions (like Reset) require confirmation to prevent accidents

■ And more
- Manage settings for multiple devices as separate Projects
- Alerts notify you when a threshold is crossed or updates stop (Pro)
- Save Session history and export it as CSV (Pro)
- No hardware? Try the core features right away in Demo Mode

■ Free / Pro
All the core features are available for free. Upgrading to Pro removes the limits on Projects, Commands, User Metrics, and graph displays, and unlocks Alerts, permanent Session storage, CSV export, and advanced System Metrics (one-time purchase, restore purchase supported, no ads).

Languages: Japanese / English / Simplified Chinese (follows your device language)
Requires: iOS 17+
