I have been running several activity trackers on my iPhone 6 with iOS 8 including Argus, Nike+ Move and Human. They are all great apps and a lot of fun, but they do require quite a lot of battery power because they run in the background and three is just too much. One is all you need and all you can afford unless you want to charge your phone twice a day.

Sitting at a desk all day is not good for you and too many people spend too much time sitting down. To keep yourself fit and to fight the flab you need to be more active. Even if your weight is OK, your muscles will weaken if you spend too much of the day sitting. Argus is an app for the iPhone that will help you to track your activities and get fit and healthy.

There are many fitness tracking apps for smartphones that are able to monitor running, walking, cycling and other activities and we are spoilt for choice. Moves is an interesting one because it works automatically and you don’t need to manually start it and stop it. It just works. Link it to HealthVault and it becomes even more useful.

Some people say that the brain is like a muscle and like any other muscle, if you exercise it, it will improve. It won’t get physically larger like other muscles do, but it will become more efficient and you can increase your brain power. Lumosity and Fit Brains are two competing brain training apps for Android that are designed to make you smarter.

You know you are addicted to technology and the latest gadgets when you can’t bear to be parted from them, even when you are sleeping. Do you keep your phone or tablet by the bed? Are pesky notifications waking you up in the night? Here is how to get a good night’s sleep.

Moves is a health and fitness app that has just been acquired by social networking giant Facebook. What does the app do and why would Facebook want to buy it? The app is free so why not add it your Android phone or iPhone and see for yourself?
