  • Bad news
  • No funciona
  • Luego de instalsrlo varias veces la aplicacion se bloquea al principio y no funciona
  • No se puede utilizar
  • App needs background app refresh option so find phone will work properly and so weather will stay updated, when app is minimzed
  • App needs a Celsius/Fahrenheit selector for weather as well as imperial/metric selector for other data
  • Also suggest a schedule to set up custom hours for the do not disturb option
  • The only problem is the dial market is very hit and miss
  • Watch face market never loads
  • The two times it did couldn’t download watch faces
  • Better without not even worth it

  • App is crap!!
  • I was given a watch that goes with this app, ut the app freezes up on everything
  • Can’t load anything from the app
  • Worthless!!!!!
  • Q R code
  • It is saying that the Q R code is invalid
  • Dial Market freezes the app!
  • I have successfully set up and using my new smart watch which is working well, but when I use the app to customise my dial face the ‘Dial Market’ (spinning wheel of death) section of the app continually searches and ends up freezing the app and the app needs to be reset to work again
  • Having to only use the default dials that come inbuilt with the watch and not able to use the Dial Market at all to customise the face which is a shame
  • The rating is for the app, not the watch !
  • The app is very difficult to use on a IPhone
  • Every time I try to open the app it locks up

  • Unable to set up the time?
  • I have difficulties setting regular time even when the watch is connected to my iPhone???
  • Appalling
  • Cannot register
  • App won’t download face dials
  • Watch stuck in transmission mode (I only know this using Google translation of a Chinese message on the screen)
  • Totally useless watch and totally useless app now
  • No way to troubleshoot or log a complaint
  • Avoid!
  • App not working
  • I have downloaded this app to connect to my watch but I am unable to this as the app is requesting me tk create and account but the button does not work
  • Please can you fix this ASAP
  • Some functions don’t sync
  • I have the AW12 smart watch and can’t get the heart rate data to transfer to the app or the heart rate to track daily which is what it looks like it should do hopefully this will be fixed soon
