How long does it take to sync? It depends on how long you go without syncing. It can range from 5 seconds to 2 minutes. Within the progress circle on the home screen of the app will show "syncing..." while this process is taking place. Have more questions?

At the beginning I was getting an "error locating" message but that worked it self out but it still won't sync. Any ideas? 1 Kenyatta Robinson June 10, 2017 18:57 I'm having the exact same problem. On day 2 with my new bottle, the app continuously says "Searching". I tried restarting both the app & my iPhone but the problem persists. 0 Amanda Heaton Karki June 13, 2017 14:59 Same here. It synced once this morning but hasn't synced since. I've had to manually enter the ounces. I bought this bottle so it would do it for me and I wouldn't have to worry about it. 0 Kenyatta Robinson June 13, 2017 21:00 Changing the batteries in the sensor worked for me. https://youtu.be/14vhCTJyeA8 Please sign in to leave a comment.
