Whatever you're up to, there's probably an app that can help you do it cheaper and faster. All of these free apps can either save you time, money or both.
This taxi hailing app is pretty well known, but for good reason. It can take the stress out of finding a taxi, and often costs less too.
You'll need to set up an Uber account with your card details to use the app, and then you can request a ride. It scans for you nearest driver who comes to pick you up.
It shows you your driver's details, like their name and car model, so you know who to expect.
When you reach your destination you just jump out and the fare is taken automatically from you card details, so you don't need to worry about having cash on you.
It can do both. Uber is often cheaper than a normal taxi fare, and because it links you with your closest driver, they can be quicker too.
This delivery app turns your local restaurants into takeaways, so you can enjoy your favourite dish without leaving the sofa.
You can use your phone's location or enter a postcode to find local restaurants signed up in your area.
All you need to do then is choose what you want and wait for it to be delivered. You can't pay by cash, so the bill is settled using the card details you enter when you sign up.
This app is all about letting you enjoy your favourite food without the hassle of leaving the house. It could end up costing you more because you'll have to pay a delivery charge on top of your bill.

This ingenious app links other apps together to make your life easier.
It offers hundreds of 'applets', which are where two of your existing apps or services work together to create something new.
