Fitbit

Don't you know Fitbit? I recommend you to give a tour through their site Fitbit.com since it's way more than a simple app: it's an ecosystem of gadgets, professionals, software and hardware oriented to help you form new healthy lifestyle habits.

Even you aren't really into buying that sort of gadgets for monitoring your activity, I invite you to give a glance at this app. If you're an absent-minded, disorganized and chaotic one, this is going to help you put some order in your life. What better than starting from how you look and feel?

Once signed up, you'll be able to input your personal data like weight and height, weight loss goals or activity goals like kilometers or steps/day or week. Likewise, you can input food and quantity you're eating along the day. There's a huge database of meals and its calories. This way you'll know how much activity you have to do in order to fulfill your daily calories goal.

It can sound annoying inputting all your meals and, actually, first days you can feel that way. However, if you're persistent, you'll get into the habit and then Fitbit will work for you: stats from the very first moment you added foods and activity, weight loss, advises and many more. It's fully compatible with other apps like Endomondo, TargetWeight or Fitbolt (amongst others).

The only catch is that it doesn't comes with a built-in geolocation-based tracker. However, that's its gadget for: it syncs all that info to your Android app or PC via bluetooth or WiFi.

One small app in your device, giant leap in your lifestyle.
