Ideally it creates a CSV file and stores it on an SD card or something. I’ll even use on that requires an app as long as that app doesn’t make me create an account.
UPDATE:
I went with a Withings BP cuff. It doesn’t meet the above criteria at all, but I already had a Withings account from years ago before I was concerned about privacy so I wasn’t giving my info to someone who didn’t already have it.
I have one that records the history on the device; up to 100 entries per user or so. I don’t know if there’s an export option though; I’ve never tried.
If you’re interested, I’ll look it up. I’m not at home for a bit so I can’t just go look at it; I’d need to dig through emails to find the model.
Why not just manually log?
Because I’ll never keep it up to date. I’ll be in a hurry or something and just measure it without recording.
I usually shoot a photo. faster and cheaper. why buy something new if you can do it with stuff you already have :)
