TL;DR
- Luna is rolling out Luna Voice across its smart ring lineup.
- The feature lets users log habits and ask questions about their metrics using voice commands instead of taps.
- On iOS, Luna Voice works via Siri; Android users can use voice interactions inside the companion app.
Luna Voice Overview
Anyone with a wearable knows that manual data entry is tedious and often abandoned. Luna aims to make that step easier with Luna Voice, an assistant‑based feature that lets users log habits and check health data by speaking rather than navigating through the app. While wearables are becoming more conversational, voice‑driven daily habit logging remains relatively rare.

How It Works
- Data entry: Users can record details such as meals, caffeine intake, workouts, or how they feel. This information is integrated alongside biometric data captured by the ring’s sensors.
- iOS integration: Trigger Luna Voice through Siri with phrases like “Hey Siri, track with Luna” to log an activity or “Talk to Luna” to start a conversation.
- Android integration: Voice interaction is available through the companion app using the phone’s assistant.
- Scope of queries: Luna Voice can answer questions about sleep, recovery, stress, and performance.
Note: The ring itself does not contain a microphone. All voice processing occurs on the phone via the companion app and the respective voice assistants. Hands‑free logging from the lock screen currently relies on Siri, making that specific workflow iOS‑only.
Availability and Pricing
- This is a software update, not new hardware.
- It rolls out across the current Luna lineup, including the latest Luna Ring 2.
- The Luna Ring 2 starts at $329.
- In testing, the titanium ring felt comfortable and distinctive, and the app provides a broad set of wellness metrics without requiring a subscription fee.
Impact
Reducing friction is one of the clearest ways wearable companies can improve the user experience without adding new sensors. Luna Voice doesn’t change what the ring already tracks; instead, it streamlines how users interact with their data.
