iPhones are expensive, but iPhone software is mostly quite cheap, and a lot of it is free. The problem is finding the good apps - the ones that are as good as the paid-for alternatives, only supported by non-annoying IAPs and/or adverts - and filtering out the dross.

Luckily we're here to help. Our roundup gathers together 81 fantastic free news, photography, entertainment, work and social apps for the iPhone.

Our first category is:

Social apps

Reddit Official

Reddit's free iPhone app replaced the old Alien Blue Reddit app, which until April 2016 was the closest thing to an official Reddit app we'd seen so far. But now, Reddit has used what it learned from Alien Blue to come up with its own app built from the ground up.

You'll see the latest news, trends and memes available to browse, search and discover within the app's clean, easy-to-use interface. You'll also be able to access your inbox to stay up to date with messages, comment replies, post replies and mentions.

Buffer is a neat tool that lets you easily post - or share pages you've found - to multiple social media accounts (although only a single account per social network, unless you upgrade to the paid-for version) at scheduled times.

It's fantastic for media and business types who've used analytics to find out the optimal time to send out tweets and Facebook updates; you can set up a series of strong posting times, and updates will automatically be queued up for the next window.

If you're on Facebook - and if we're honest, most of us are - then this is probably the first app to download on a new iPhone. It's free, it looks good and does a good job of getting out of the way and letting you find out where your ex-girlfriend has been on holiday.

Facebook introduced Messenger to the world in 2011, and since then it's grown into a communication app burgeoning with features. You can use it as a straightforward messaging app, for either one-to-one or group chats, but there's also the ability to make free calls over Wi-Fi, and even play games with other Facebook users.

Like Facebook, Twitter's free native iOS app is simple and effective. It's intuitive to use and ideal for the more basic aspects of using the service - which is what you want from the iPhone app. Use it as an up-to-the-minute news service, social media stream, or as a way to enact foreign and domestic policy if you're the president of an international superpower.
