I wear a Colmi Ring and a Fitbit. Steps, heart rate, etc overall track very similar. Using the ring because after buying Fitbit discovered it does not sync with Apple Health. Only really terrible feature is sleep tracking. Measure sleep after waking up for up to an hour. Also if you wake up in the middle of the night it will not notice. When I compare with my Fitbit that measures sleep very well, I have on average 30 to 60 minutes less sleep each night than what the ring measures. Not great also is rest or stress level. Very different values to my Fitbit, and I can feel that my Fitbit is much more accurate in detecting if I trained to much and need rest or if I am stressed overall. So if you goal is tracking steps and heart rate, go with this app and ring, for anything else you will be disappointed.

I purchased the Herz P1 ($60) so I could track my sleep without wearing s watch. I noticed that the sleep tracker always adds an extra hour of sleep. This app does sync with Apple Health but Apple health tracks the sleep accurately so I view sleep from Apple. The sports record had several activity selection but basically records the same way, you must scroll to select an activity, you cannot search and it's not in alphabetical order. The stress level monitor is fairly accurate but you can check twice within 2 minutes and the numbers will be much higher or lower. The steps appear to be accurate,

The new firmware that I loaded on 9-8-24, via this app, on my R02 Colmi smart ring changed the whole app and made connectivity, previously very reliable, spotty at best. The app lost the stress and blood oxygen “cards” so there’s no way to monitor that data. Still gives the option of monitoring them both throughout the day but there’s no place I can find where the data lives. Stress reading was always useless (the reading never changed despite massive stress or deep relaxation) but I have sleep apnea and want to know if my oxygen levels drop during the night so I can mix up my position, supplements, etc. in order to have a better night’s sleep the next night. Sleep tracking, while it’s finally tracking my REM sleep (zero REM sleep prior to firmware update), after the update, despite having a full night’s sleep, it’s not registering that I’m sleeping at all on some nights and other nights I’m asleep for seven hours but it says I slept three hours. Used to not have these problems. The connectivity is now very spotty. Connects enough to transfer data but forget about real time measurements of heart rate (the only remaining option for real time anything) as the ring disconnects after a maximum of 30 seconds. $5.99/month for an aura ring subscription is starting to feel like a good deal.

For example, you can move the vertical bar to show you what your heart rate was earlier in the day but it doesn’t actually show you what time that was at. Same thing for stress, sleep, blood oxygen.I’d like the option to sync workouts from your phone to the app on iOS. It’s weird that it’s not able to do that. It would also be helpful for higher numbers to be available for menstrual cycles. There are lot of women that have cycles WAY longer than 35 days. I can’t use that feature at all right now.
