The overall concept I really like. I think the app has some neat features that makes the mask do some interesting things. My biggest issue is that the mask cuts off when my phone gets put to sleep, even when my battery is fully charged on both. It would be the equivalent of a music app going on pause when the phone goes to sleep. Doesn’t do you much good. There must be a way with all the technology in this world to establish a better connection between the phone and the app.

Overall Everything Works Very Nicely

I’m glad to see that the iOS14 issue was addressed very quickly. Nice job with that! All the different LED settings work very nicely! I don’t have any issues connecting to my LED device. It actually connects very quickly.
However, I do have some feedback to hopefully get these issues fixed in a future version...
First, in the MUSIC/VOICE area there are 4 different types of audio graphs but it only lets you use 2 out of the 4 graph styles. When you touch some of the other ones it just stays using one of the 2 styles that work.
Second, on the main screen of the app as you try to go into each area by touching the orange label button for that area, it works perfectly. However, if you touch the picture above the button, it takes you to the wrong area.
Third, if you’re using dark mode on the phone, in some areas the letters are impossible to see. Like in the CHARACTERS area I can’t see the text I’m typing. Temporarily switching my phone to light mode fixes this so it’s not that big of a deal but it would be nice to not have to switch.
Thank you!!

Almost there

Great idea, still needs work. Almost everything on mine works except music (music worked at first but stopped almost immediately) whenever I try to use the music function now, the app crashes. Hopefully they will find a fix for it. Otherwise mine connects no problem and all the other functions work fine (even the voice section of the music function)
