Ratings and reviews

Recently the app force closes when reaching 87% on sync. I get a pop up message that says : "Something went wrong with Circular Circular closed because this app has a bug. Try updating this app after its developer provides a fix for this error." If I do a factory reset I'll lose all the data I've collected since receiving the ring. The app needs to be fixed & not just say to do a reset. Plus I'm waiting for the extra functionality that was promised.

Updated: 11-13-2025 The apps stability isn't consistent and now my ring won't connect. Previous Update The app and ring were good for a few weeks, but after the most recent update 28.6.3, the app won't open. And when it does, the data doesn't sync all the time. The most frustrating thing happened today when the app opened and my ring was no longer paired and all my data was gone which means I have to go through the whole setup again and start from zero.

The app is useless. It takes way too long to sync, sometimes 20 minutes or more for my sleep data, just for the app to tell me it's having server issues. I can basically track my heart rate and my steps (which it tracks only about half of) and that's all, and even that is hit or miss depending on whether the app decides to sync or not. A complete waste of money. It's just overpriced jewelry at this point.
