What's New in Luna Band and Ring

2.0.6

October 22, 2026

What's new in 2.0.6 NEW • Sleep Alarm — plan your wake-ups from your usual bedtime. The alarm is written to Luna Band with your phone as backup, snoozing on the phone buzzes the band, schedules re-plan when you change time zone, and the haptic slider now sets the band's vibration intensity. • Haptic Health Alerts for Luna Band — heart-rate thresholds are armed on the band itself, so it buzzes even when your phone is out of reach. Off-body alerts are back: 15+ minutes off, at most twice a day. • Japanese — Luna now ships in 14 languages. IMPROVED • Firmware: the update check moved to the v4 API with improved states, and the band can update off the charger above 20% battery. • Band sync: workouts the band drops mid-session are saved instead of stuck on "still saving"; auto-detected sessions with an empty report file are recovered from the point-file header; nights that synced without HRV are repaired. • Health: one-tap heart-rate and stress readings upload immediately, the measure sheet shows the live reading instead of a countdown, and skin temperature shows the change from your baseline. • Alerts stay quiet while you sleep — move reminders and heart-rate alerts no longer fire when the last sync found you asleep. • Chat: meals logged with Luna show a chip with Undo. • Home lets you know when a newer version of Luna is available. • Goals can be set in any language, and Apple Health receives distance and calories when workouts merge. FIXED • A token refresh racing device registration no longer signs you out. • Freezes: image encoding, log snapshots and chat streaming moved off the main thread, and firmware updates get a 90-second watchdog. • Sleep stages now appear in time order, tapping a detected walk opens its summary, Terms links open the right device page, feedback drafts persist, and stress labels are coloured correctly in every language.

Drain battery like crazy

Aside from the numerous issues with the Luna band and the lack of all the promised features, the app is now causing excessive battery drain on my phone. Use the app for 1 minute and it will drain my iPhone 17 pro battery by 2%. I have to turn off background app refresh and make sure to close out the stop completely after I go in the app to view my stats.

Not ready yet

I’ve used the band for 6 weeks and have been totally frustrated. The software isn’t ready at all and many data aren’t believable. No updates for fixes in weeks and consequently I feel I’ve made a huge mistake buying this band. It looks nice but that’s it. Great potential but wasted effort.

Hate the new app

Really disappointed with the new updated app

Do not buy!!!

I used to tolerate the ring before the app update. Looking away at the lack of accuracy. But now with the new app it is pointless. Impossible to understand, impossible to read the data is Extremely confuse. My ring disconnect often.

But my mayor concerns are:

1. This morning my ring disconnect and trying to re-linking it. I click the option of “find my ring” and showed that my last location was “New Delhi” mind you I live in Texas. So why is my data showing in India? Hardly concern.

2. My period tracking, the whole reason i bought this ring was to track my period base in the basal temperature as they promise in the website. But I came to realize after going through a misscariage that they don’t use the basal temperature to measure my periods and ovulation period. Rather they predict this data based on the data you feed the app.
How do I know this? Because I noticed the predictions completely off so I asked the app IA and told me this. Which makes sense because according to the app my period last 50 days!!!!


How this app has 4 starts? No clue!
