Does this watch show blood oxygen (SPo2)?

What does show up on my Versa 2 is a graph of Estimated Oxygen Variation. When you bring up the graph showing the sleep stages during a nights sleep, then scroll down past the bars showing the time spent in each stage, you find a graph of the estimated oxygen variation. A low variation is good and shows as a fairly stable green line - probably in the range of 90 percent oxygen saturation and above. A spike to higher variation - which might indicate apnea - shows up as an orange peak. A couple of nights ago,my wife woke to get me to roll to my side because had been snoring loudly for a while. When I looked at my sleep trace the next day the oxygen variation was low and steady until about a half hour before she woke me, then jumped up and continued rising as an orange line until it suddenly dropped to a normal range - probably when she woke me. Note: I had a sleep study done in February, which confirmed I have episodes of sleep apnea - mainly when I roll onto my back. I am being fitted for a CPAP on Friday,

can i get this without alexa?

You do NOT have to activate Alexa when you setup. But it is very cool. I was just driving and I asked Alexa how far to destination. BAM!

Can you receive text messages from an iphone?

I have an iphone 11 and a Versa 2 and yes, you can receive text and phone calls, just not reply or answer without the phone nearby. Nice feature with phone is, you can reject the call from the watch. It needs to be close enough to the phone since it’s bluetooth. It will not do it if it’s not connected to the phone. This feature worked even on the Blaze I used to have connected to an iPhone 8.

Does this work with an iphone7

Absolutely. I have an iPhone 7 and the Fitbit app works well.
