I used to have a pedometer app on my phone...I used it as it stayed on in the background...but after a days work and putting in anywhere from 8 - 10 miles a day, it just reminded me of how hard I was working, so I deleted it! ;)
Mine counts the steps accurately enough but has absolutely no idea of my step length (and can't be adjusted) so I know how many steps I've taken but not how far I've walked.
My phone came with a fitness app but never used it. I do have a Fitbit and it is synced with my phone and laptop. I don't pay attention to my steps that much, mainly because i know I don't walk as much as I need to. I am trying to get into the mindset to better that. I do focus on my sleep. I do not get as much as of that as needed either. I have increased that by an hour a night though since i have been paying attention to it. I am still woefully short though. I am up to an average of 6 hours and 20 minutes. I don' know if I will ever get the recommended 8-9 hours, but I would be happy with 7.5 hours.
Yes and yes. With the combination of crap weather and being under the weather myself, I've been telling it to f off quite a bit lately. Still won't shut up, every couple of days it has to tell me what a loser I am.
