Foodvisor

IOS + Android, Free ★★★★

This ingenious new food tracker logs your meals and their nutrition value from photos of what you eat.

Just snap your plate and the food-recognition technology will know what you’re having.

And it will cleverly calculate calories, proteins, carbohydrates, fats, fibres and cholesterol to make sure you are having a balanced dish.

You can also manually log items and scan barcodes too if your plate is overloaded, such as for your mum’s Sunday roast lunch mountain. The data is then used to work out your daily calorie allowance to help you hit your target weight.

The basic version is free to use and includes the scanner, calorie counter, stats charts, a few recipes and the blog.

But you can unlock wider premium features – including more healthy recipes, diets and instant live chat to a real nutritionist – from £4.11 a month.
