App is garbage!


This is a garbage app. If you just bought the Chronos and are about to download this app. I would strongly recommend getting your money back. This is infuriating because it would actually be a decent product if they could get the app to work. It constantly loses connection and crashes. Half the app functionality doesn’t work. I deleted the app with the intention of reinstalling hoping it would make the app work better. And much to my dismay the app mysteriously disappeared from the App Store for about 3 weeks. I tracked down the CEO and messaged him through LinkedIn and threatened to report them to the BBB if they didn’t respond to email inquiries (this was after several emails to Chronos support with no response) about not having an app available which renders the Chronos useless. Shortly after that the app returned to the App Store. Lots of headaches and not really worth the trouble. Wait until someone comes out with a similar, fully baked product.

Great start


I really enjoy my cronos but there are a few problems I've noticed. The device and my phone seem to lose connection if I haven't opened the app recently. My phone will vibrate with a notification but my watch won't respond. As soon as a open the app again it seems to work better. I've tried it out with a fully chargers battery and a low charged battery with the same result. My other issue is that the find my phone feature. Half the time it works perfectly. The other half it won't make a sound or send a notification to my phone. When this happens I've noticed that the volume will still change on my phone but no noise or anything is made. Overall I love the device though

App ok Defective product

Waiting in traffic

The app is ok, but the product it works with is defective. The back plate on Chronos disc keeps falling off. I received a replacement after customer service took three weeks to answer. The second ones back plate came off after three weeks of use. And customer service said they would not refund because it was longer than 30 days. I sent another email to explain it was less than 30 days and they changed to 14 days for money back. Based on the claiming numbering system, you can see they are getting a lot of defective products.
Update. After months of emails back and forth, I finally got a refund. This product had such great potential.
