Christmas dinner is, notoriously, the most stressful of meals to cook. From putting the turkey on several hours before you even think about sitting down to trying to balance a mountain of trays in your oven, while laying the table and greeting your guests, it can become overwhelming if you haven't made a plan beforehand.

But thankfully the dawn of the smartphone and tablet means that there are now hundreds of apps that can help with timings, recipes and even leftovers. And without having to flick through books that end up covered in gravy, many of these apps can be used hands free so that you can get 100 things done at once, and end up looking like superwoman.

Prepare for a calm, argument-free Christmas.
