I've used Nike Fuel, FitBit Force, Jawbone Up and Withings Pulse. I just ordered FitBit Surge and I'm waiting for it to arrive.
You can find detailed reviews online on everything online but imo the top 2 are FitBit and Jawbone, keep in mind you can't monitor anything on Jawbone without the app.
To cut to the chase, I lost 26 kg on FitBit and I wouldn't look at anything else, it's not THE best in any single area but it's pretty good at everything.
Research FitBit Surge and FitBit Charge HR, best of luck :)
I have the fit bit and really like it. the battery died or I just need to charge it so its sitting on my dresser lol. Pretty reasonable on ebay.
If you're okay with having no screen check out the Jawbone Up3 it has good potential, otherwise stick with FitBit :)
Best of luck
We like the Fitbit One and I've had success with it since April. The display shows steps, intensity of exercise to motivate you to walk faster if you're inclined to stroll rather than walk briskly, shows floors climbed, and more. It's small enough to wear clipped on a pocket or strap. It recharges via a proprietary cable like a phone does so you don't have to change batteries. It's android, apple (i-phone), and pc compatible. The site relies on the US government recommended nutrition guidance.
I'm currently using Fitbit One and used Fitbit Surge before. The good thing about these gadget is that it allows me to set my targets for walking/running.
It does push me to meet my targets daily.
The downside of it though it does not capture my activities when I do weight training. Nevertheless, I know those activities do add into my daily calories burnt.
Now, I always carry my Fitbit everywhere I go. If by early evening I have not achieved my targets, I'll make up for it by exercising at night.
