People are just realizing iPhone has built-in ‘spoiler mode’ that stops friends ruining movies – it’s free and so easy

YOUR iPhone has a secret feature that makes it much easier to discuss movie spoilers in group chats.

If you’re worried about ruining a plot point for someone else, you need to try it out.

It can save you from giving away key details about a TV show, movie, video game or book to people who aren’t as “caught up” as you.

Tucked away in your Messages app is a little-known feature called Invisible Ink.

A message sent using Invisible Ink will be blurred for both the sender and recipient.

The only way to reveal it is to swipe over it.

This will temporarily show what’s inside, before concealing it again after a few moments.

You can use Invisible Ink to discuss spoilers in an iPhone group chat.

Pre-warn the group that you’re talking about spoilers for a specific show, then begin your Invisible Ink messaging campaign.

Then people who want to read the spoiler content can choose to un-blur your message.

Meanwhile people who want to stay protected from your texts can leave them concealed.

Of course that’s not the only use for the iPhone hack.

It also makes it much easier to text more privately in public.

If you’re worried about someone peering over your shoulder, Invisible Ink can give you greater privacy.

This is perfect if you’re having a private conversation over iMessage on cramped public transport or at a busy bar, for example.

To send an Invisible Ink message, go to the Apple Messages app and open an iMessage chat.

Then type out a message and hold down on the Send button rather than tapping it.

This reveals a hidden menu with several options.

You want to choose Invisible Ink, and then hit Send.

Now you’ll see that your message has been concealed for all parties – and can only be read if someone taps or swipes on the text bubble.
