It does have a lot of potential with more features than watches costing far more but I'm not hopeful that they will listen to suggestions.
It looks as if they have ported Android cellphone software to the watch but without really grasping some of the problems presented by a 1.54" screen. For example, it can send/receive SMS & MMS but neither are practical IMHO - the screen is too small for a keyboard. It's even too small for entering configuration data. It would be better if all of the configuration could be done on a PC and transferred via USB. Most onscreen text is far too small to read.
It has these APPs...

arranged 4 per screen (each column above represents a screen) and you can swipe left/right to navigate.
*I suspect they mean HeartRate as this measures pulse & BP.
Voice Search might be useful if we could tap into it for using voice commands, to make phone calls, even to type in letters/numbers in lieu of a keyboard. IOW, make it a Siri or portable DOT.
I fear my ongoing health issues may limit my contributions to making suggestions.
I found no way to disable the Lift Wrist Display - only to set the default time its ON with 15 secs MIN. It needs to be disabled to prolong battery life. I left in its cradle overnight and put it on at 8:00AM with a fully charged battery. I have no SIM yet so this will not be a definitive test of the battery but it is a start.
It says it has 11+GB available but also says 8GB MAX - another indication that it's NYRFPT.
I think the buttons are problematic for most geezers or frail LOLs. The ON & BACK buttons could be replaced by a tap for ON And a pinch for BACK. I'd keep the SOS buttons as they will not be needed all that often.
PS: As yet there's no word on when the promised API might be released.
