This is Kit Eaton for the New York Times. Losing a little weight is something we all try at one time or another. For my body and lifestyle, the app Breeze which is free for iPhones really does work. In an essence it's a step and activity counter based on the oft-quoted idea that you should walk around 10.000 steps in a day to help keep your weight down and you in shape. Breeze basically monitors whether you are walking enough and gently prompts you with cheerful reminders if you've done well or if you still need to walk a little bit extra to achieve your daily goal. It's simple, highly motivational and I find its gentle prompts really do keep me on target. The app only works on an iPhone 5S and more recent ones. But if you're looking for a slightly more full-featured weight-loss app you should check out Lose it! which is free for IOS and Android Lose it! tries to be a one-stop-shop for smart phone users who are trying to lose weight effectively counting as a calorie counter, a dietary advice database and a fitness and activity tracker. To do this it requires a little bit of input from you. Mainly in the form of tagging how many calories you're eating in a particular meal. The app tries to help with this task via a vast database of calories and particular meals and a bar code scanner for when you're cooking your own food. But while core features of the app are free, to get access to all of them, such as an analytic section to help you find out where all your calories are coming from, you have to pay up to $40 per year. So a great alternative to this app, albeit one that's slightly simpler, is myfitnesspal's calorie counter. This app is completely free for IOS and Android and has many of the same features as the previous app, including the ability to connect to third party fitness tracking devices, If it has a slightly plain interface. But don't let that put you off. And above all remember that to use any of these apps you really get the most out of them when you're committed to losing weight and getting a little bit fitter.
