More useful than SMS, slicker than Hangouts and easier to use than Skype, it's no wonder Whats App is the number one communications service of choice for hundreds of millions of smartphone users.
On i OS, you can see exactly how much space each of your chats takes up by navigating to Settings Storage Usage. You can save shortcuts to your favourite Whats App conversations directly on your home screen by tapping and holding a chat and selecting the Add Chat Shortcut option from the menu.
From there, you can easily free up space by deleting the content you definitely don’t need, with filters allowing you to get rid of specific file types, such as videos, pictures, voice messages, documents, contacts and locations. It will create what looks like a brand new app, adopting that particular conversation’s title and picture as its name and icon.
Unfortunately, it also makes it tough to ignore somebody without upsetting them.
Fortunately, there are ways to covertly read your messages, without those blue ticks appearing on your friend’s screen.
If you’re a multi-platform whizz, you can go a step further by actually exporting conversations as emails.
Emoji will be embedded automatically, which is clearly a great thing, and you can choose to include or leave out media attachments.
A constant presence on Google Play and the App Store’s top apps charts, it’s one of the first apps you’ll download when you buy a new phone and almost certainly your biggest source of notification on a typical day.
The app has developed dramatically since it emerged almost a decade ago, picking up the ability to transfer files and make voice and video calls – all now core features – along the way.
As with emails, you can easily mark key messages with a star, allowing you to find them easily when you want to.
Simply tap and hold a message and hit the star icon to save it, and return to it later by selecting Starred Messages in Whats App’s main menu.
If you don’t like the idea of someone else reading your Whats App messages as they flood in, through the previews that pop up on your screen, you can simply restrict the amount of information they display.
