Theres a lot to like about the Vivofit 3, mostly the fact that I can shower, swim, and wear this all day and night without recharging!
The screen is small but very sharp and clear, and it's big enough to read at any arms length. Seriously, if you have any concerns about legibility, the numbers are bigger than the ones on the keyboard i'm using right now. if you can read keyboard numbers, then you can easily read these numbers. If you press the button, there's a light that reminds me of my old casio watch. lights up easy to read, at night, but outside it's perfectly fine.
Having used this for about 2 weeks, I love the little fireworks animation and the calendar animation for days I've gotten consecutively. Its a small thing but it keeps me motivated to keep it up. The alarm is kind of quiet but it's not any quieter than my old casio digital watch.
Syncing is mostly OK, I've tried it a bunch of different ways and i think i've found what works best usally. I open up the app, press the button until the screen shows the sync symbol, and put my phone right next to the vivo. it usually takes a minute or so. It's not always connected because it think that's how it can keep the battery for a year.
At first I thought it wasn't recording any activities because for the longest time it always showed nothing in the activities window. But i discovered a couple things. If you start the stopwatch by holding the button down, and letting go when it says START, then it starts a timer. Then I go for a run and when I'm done, I hold it down to STOP it. After I sync, then I get a "1" in the activities and it shows what I did. It DOES NOT do this if you just go for a run without starting the timer.
The other thing I found is that when you're in the app, you can find a timeline of your day. Usually it's a squiggly line of movement, but if you go for a run without using the timer, there's an icon that shows I was running. If you hit it, it shows your time, it's call MOVE IQ. It does this for Elliptical, Walking and Running, but I haven't gotten it to work with biking or swimming yet. I think it's because I'm not doing it long enough. I looked back through the last few days and I can exactly tell when I was walking my dog cause there's a walking symbol at 6:30 or so each night. AWESOME!
The app is pretty good if you can spend some time figuring things out. I think its like anything else, you have to try it a few times to get used to it. For example, it took me the longest time to figure out how i could change the watch faces. There's so many settings, but I finally figured it out. You also have to back out of the settings all the way and THEN sync. If you just sync it won't change anything. After I realized that, then I experimented with all the different watch faces and settled on the analog watch face. It fits really nicely and I've gotten a bunch of compliments about it from people at church and work. I also LOVE the split screen watch, and might go back to that when I get tired of this one.
As far as the band its pretty big on me, but i think they're trying to make it work for a lot of people so whether your big or small it should fit. If you're really thin, I think amazon sells some other bands. I want to get the camo band but there's some others I think. The little circular clasp is easy to turn to lock. I forgot to lock it a couple times and it almost fell off, but if I lock it, it's not going anywhere. The band itself is nice and smooth, really soft.
A couple of wierd things for me is that I do get something like 50 or so steps at night. What's up with that? Maybe it's because my arm was moving? Also, I think it doesn't track steps when I'm pushing a shopping cart or something like that. My friend told me to strap it on my belt. I'll do that next time.
