Apple Bluetooth connects to it just fine. Nonfunctional. ### 1/5 — Crash *2018-04-25, version 1.11* Android app keeps crashing and cannot get into iOS version with my email and password. Ripped off, again, by another euro trash crap outfit.!🤔 ### 1/5 — Really *2016-01-14, version 1.10* I don't know which is worse, your product or service. Bottom line; they're both really bad. ### 1/5 — Annoyed *2015-04-14, version 1.6* Doesn't sinc on iPhone 6, continues to say loading resulting in me shutting down my phone. Then I get a message "network unavailable" app totally stinks, they really need to fix this app for iPhone as it's useless. ### 1/5 — App won't sync *2015-04-06, version 1.6* None of the stats interact with the iPhone's Health app. The first few occasions that I used the app, it synchronized with my Zefit with no issues. Since about day 3, it seems to sync but shows no info in the app and constantly gives an error message of "network unavailable". I have tried on wi-fi and 3G and I have repeatedly restarted by phone and switched my Bluetooth off and on. It's rather disappointing that the official app for a device is so useless. You're better off writing down your stats on a piece of paper. ### 4/5 — Make Updates Easier *2015-01-31, version 1.6* Please make updates easier by instead of using computers use App Store updates. ### 2/5 — App always crashes *2014-12-06, version 1.6* Since I just make it through the set up phase, I cant synchronize anything because the app continues to crash. Ive sent an email to the support team and they dont even respond. The app doesnt work at all for me ### 1/5 — Just Does't Work. *2014-09-27, version 1.3* The app doesn't at all. It keep crashing on me. I already install a bunch of times and keeps not working. The Watch is not accuret. I sent a e-mail to them and I didn't get any answer. Don't waist your money on them. ### 1/5 — When will you release a version 2.0? *2014-09-07, version 1.3* Stability is low, app crashes time to time! Sync needs internet connection. Is it hard to add an offline synchronization? Also the data sometimes it is different on the device and in the app. Alarms sometimes do not work. Sleep mode also turns off automatically when I just wake up to drink some water in the night, so I would recommend you to add an option to turn off sleep mode manually. Really, you released an interesting device so why are you not trying to create really user-friendly and stable app? ### 1/5 — App not connect to zefit *2014-08-25, version 1.3* Hard to use and can’t connect ## Frequently asked questions about ZeFit ### What devices is ZeFit compatible with?
