Once they got their money, they bailed out. ### 1/5 — App stopped working *2023-01-14, version 1.4.7* It just says “you’re offline - check your connection”, as of a month or so ago. ### 1/5 — Shut down *2023-01-13, version 1.4.7* The app has been shut down it’s useless just like all matrix watches are now useless as well ### 3/5 — App has died! *2023-01-08, version 1.4.7* Same for me as for other recent reviewers. The app logged me off, and no matter what I try (new account, log in, forgot password, etc.) I get a “not connected” or “can’t send email” notification. Watch still functions. I hope it is able to sync time over bluetooth when necessary. ### 1/5 — Seems abandoned *2023-01-08, version 1.4.7* Watch worked great, app and viewing data seems to require internet, no internet = no data. Who are they selling the data to I wonder. App is no longer working, required servers seem offline. Don’t buy the watch as you won’t be able to use it without the app. ### 1/5 — App stopped working *2023-01-05, version 1.4.7* Power watch 2 app stopped working and not allowing to login or reset password. Support team is also not responding to mails. ### 4/5 — App mostly great *2022-12-27, version 1.4.7* The app was great up until a week ago when it logged me out and stopped working. Now it says “you are offline, check your connection”. I love the watch and how much battery life it has, and the app was cool too, up until it stopped working. ### 1/5 — Full of bugs *2022-12-26, version 1.4.7* I have had this watch since it’s debut on kickstarter. Full of glitches. Does sync well. Constant issues with GPS. The app needs to be deleted and reinstalled for a sync at times. Only good part is it tells the time and doesn’t need to be recharged. This watch needs a major upgrade. ### 1/5 — Dud on Android and iPhone *2022-12-22, version 1.4.7* App has not been updated in years and does not function with iOS 15+ ( always says that you are offline). Was an original kickstarter contributor and have had for 5 years despite its terrible firmware struggles- it was an interesting tech that never delivered.. ### 1/5 — Update the software on this app and watch! *2022-11-25, version 1.4.7* Update the software on this watch and app the watch is just frozen in time! You did not put all the things that you promised on your website on this watch, and that’s very disappointing! Because, like me, a lot of us bought the watch, thinking that all of this was going to be on the next few software updates, but it never was,this could’ve been the best watch ever!But because of no more software updates the watch never reached it’s full potential!! ## Frequently asked questions about MATRIX PowerWatch 2 ### How does the PowerWatch 2 get its power?
