Bugs, things not working22%

★★★★★ Update: I have sent an email to support and received no response.

Price and subscription17%

29 of the 1 and 2 star reviews.

★★★★★ I know you want us all to buy the Ivy, but I bought the Leaf several years ago, and it was expensive, so there should still be an app that has more than minimal function for the Leaf.
★★★★★ For the price of this device it's not worth it.
★★★★★ The app will say that the battery is charged but when nothing is tracking and you change the battery, which in itself is difficult to change due to the very very tiny screw sizes, you find that it was the battery that…
Wrong or poor results14%

23 of the 1 and 2 star reviews.

★★★★★ Once it connects, I see my daily activity and it's not accurate at all.
★★★★★ I don't understand messing with something that is working- we need accuracy and simplicity over whatever you are going for here.
★★★★★ And most recently the period tracker is now recording the wrong dates after you save them.
Crashes and freezes13%

22 of the 1 and 2 star reviews.

★★★★★ But once i put in my password the app (and period diary) completely crashes and won't even open.
★★★★★ The app will not open even after turn phone off and on twice and then I uninstall it and reinstall it and still will not open

WHAT THEY ASK FOR
  • I wish this app didn't require so much manual entry and synched with apps that are already automatically tracking. 2★, May 19, 2024
  • I understand if the device itself is hard-wired, but the app at least, should allow for manual correction to a time earlier than 9 p.m. 4★, Jul 2, 2022
  • Personally, I'm most interested in my sleep stats, so it seems like I should have the option for the detailed sleep info screen to pop up after a sync. 4★, Jul 2, 2022
  • It would be great to have this kind of control on the home screen too. 4★, Jul 2, 2022
  • I don't understand messing with something that is working- we need accuracy and simplicity over whatever you are going for here. 2★, Mar 30, 2022
  • The new app interface no longer shows the information I want and it takes clicking through several screens to get there. 1★, Oct 21, 2021
  • I didn't expect it to be as smart as Fitbit, which guesses when you're being active and asks if you'd like to add an activity, but not even registering activity logged within its own app, not transferring distance —… 2★, Mar 11, 2020
  • An extra addition that would be awesome was if we could track our moods during pregnancy to more accurately track stress, and medications like antidepressants. 5★, Feb 3, 2020

No Response From Support

I’ve had two Bella beats and they just do not work after a while. No connecting, no response via email. Go with a more reputable company.

★★★★★Mar 21, 2025
6 years of data gone

I’ve been using this app for at least six years and I’ve tracked monthly… I’m perimenopausal and the log was very helpful as my medical providers and I navigate this phase of life. Yesterday when I opened the app, all of my data was gone. Hugely disappointing. Moving onto Apple health I suppose.

★★★★★Feb 4, 2025
Doesn't really work with my hardware

This app is designed for the Ivy device. Very few of the functions work with my Leaf. It syncs, but the Leaf doesn't have bluetooth and can't track my heart rate. I know you want us all to buy the Ivy, but I bought the Leaf several years ago, and it was expensive, so there should still be an app that has more than minimal function for the Leaf.

★★★★★Nov 11, 2024
Oh bellabeat, what happened?

This product and app worked pretty well back in 2017 but nothing seems to work now. It’s a bummer, because the jewelry is beautiful. I hope you take all the feedback from your customers to heart.

★★★★★Aug 17, 2024
Don’t waste your money

App doesn’t work, help form doesn’t work, product doesn’t work. Absolute garbage. Don’t waste your money. Zero stars. iPhone SE (2021?) iPad 3rd? gen

★★★★★Aug 15, 2024
Not accurate whatsoever

I’ve been getting more into fitness lately, and have been wearing my Bellabeat on my shirt or pants every day. When I try to sync it, it takes forever and I’m tapping it for like 5 minutes trying to get it to connect. Once it connects, I see my daily activity and it’s not accurate at all. 1.5 hours of nonstop pickleball and the app says I had 10 min of exercise that day.. with only a few hundred steps taken. I’ve been moving into a new house, and walking back and forth for weeks (I literally have not sat down more than 3 times in my new place) and still barely any steps are being tracked. For the price of this device it’s not worth it. I have the necklace/clip on leaf.. which I was so excited about at first.. but now I’m very disappointed. I hope the other products they make work better. 😔
