I have a Fitbit Charge 2 that I love. It does all the basic stuff like steps, heartrate, how many sets of stairs you've climbed, etc... I can also get text messages on it if my phone is relatively closeby but I can't reply from the Fitbit which is fine for me. It works well with Android, and has a connected GPS feature that will map out my runs or bike rides if I bring my phone with me. Plus Amazon has a bunch of really cute bands for it, so you can dress it up and match it to your outfit. Battery usually lasts about 5ish days. Mr. Ferret just got a Fitbit Blaze. The watch face is larger and you can still swap out the band to match your outfit, but uou also need to buy a "frame" separately for some styles of band, so just be warned. I'm honestly not sure what the major differences are between his and the Charge 2, I know his does everything mine does though, and probably more. The battery only lasts him about 3 days though.
