Features

What makes Trndi different?

💻

Native Desktop App

Runs natively on your computer — no browser, no cloud middleman. Just your data on your screen.

📊

Trend Graph

Displays readings in a clear trend graph with customizable color-coded high, normal, and low ranges.

🔮

Predictions

Experimental glucose predictions show where your reading is heading — with optional warning overlays for predicted lows and highs.

♿

Accessibility Built-in

Text-to-speech announces readings aloud. High contrast mode, adjustable voice and speed, and screen-reader-friendly dialogs.

📱

Touch Screen Ready

Works perfectly on touch devices — ideal for a Raspberry Pi kiosk display by the bed or in the kitchen.

👥

Multi-User

Monitor more than one person. Each account has its own source, settings, and JavaScript plugins.

🧩

JavaScript Extensions

A built-in QuickJS engine lets you write custom logic, alerts, and integrations without recompiling.

🌐

Web API

Expose glucose data to other apps and dashboards via Trndi's built-in local Web API.

🌍

Multi-Language

Ships in six languages. Adding a new language is straightforward — contributions welcome!

🎮

Razer Chroma

Lights up your Razer peripherals in different colors for normal, high, and low readings on Windows and Linux.

🛡️

Proxy & Privacy

Native proxy support, a Privacy Mode that hides the actual glucose value, and no mandatory account required.

💝

Free & Open Source

GPLv3. No subscription, no ads, no data collection. Fork it, improve it, share it.

* Linux may require additional libraries depending on the distribution.
