“It’s one of my favorite typing cues,” said Scott Forstall, a former Apple software engineer, at WWDC 2011, as the company showed off its iMessage chat app. “You can tell now if someone starts typing and they reply to you; you know you’re about to receive that message.” More than a decade later, typing indicators — the three flashing dots that appear when someone else is typing in an iMessage conversation or group chat — are still there.
But in the years since Apple’s initial iMessage announcement, iPhone users may have gotten used to a side effect: The three flashing dots can appear even if the other person is no longer typing. This can be a confusing signal in an age when most people are online and responses to instant messages tend to appear almost instantly. The explanation is quite simple. Contrary to Forstall’s remarks, seeing the hit indicator does not mean “you are about to receive this message.” The other person in the chat may have started it by mistake, because they typed a longer message, or because they changed their mind.
Typing indicators are also present in most modern chat apps, including cross-platform services like Signal, WhatsApp, and RCS. Apple wasn’t even the first company to introduce this feature, as others had developed a similar feature long before iMessage came to the iPhone as an alternative to texting. The typing indicator was just one of the first features Apple built into iMessage to distinguish it from traditional SMS chats. Other notable features included read and receipt receipts, end-to-end encryption, multiple device support, texting over the Internet, and blue chat bubble color.
Input indicators cannot be disabled

Seeing someone type a reply in an iMessage chat adds another dimension to instant messaging. This indicates that the person may be preparing a response, which may encourage you to stay in the app or come back soon. It may also suggest that you stop typing another response because the other party is in the process of formulating a response to your previous texts.
However, hitting indicators can also have a negative effect. They can cause anxiety when you see the indicator but no message comes. Or, perhaps even worse, they were typing a response and then the flashing dots stopped flashing. Then the iMessage reply never arrived.
The typing indicator feature is built into Apple’s Messages app. Unlike read receipts, which can be turned off, there is no setting in the app that allows users to turn off typing indicators. As of this writing, Apple has not announced any plans to add such functionality to its operating systems. On the contrary, iOS 26 added support for typing indicators for group chats in 2025. Other chat apps, like Signal, allow users to block typing indicators. When this happens, the feature will be disabled for both the sender and the recipient.
How to interpret iMessage typing indicators

The typing indicator can be triggered when someone activates the text field and enters text intentionally or accidentally. A longer response may also cause the three flashing dots to persist. A person participating in the chat cannot know exactly what the other person is doing. Maybe they were typing a message that they wanted to send immediately, but they were interrupted by another notification or an actual event. It’s also possible that they’ve changed their mind and won’t respond anytime soon. Maybe someone’s Internet connection was interrupted, in which case the iMessage won’t deliver despite being sent.
In 2015, Slate looked into how long the typing indicator would continue to appear in iMessage, finding that the wait time was around 60 seconds for two scenarios. In one, the user typed a few characters and then stopped. In the other, they edited the post for a full 60 seconds. In both cases, the indicator disappeared after about a minute. In 2018, Gizmodo said iMessage’s typing indicator would disappear within five seconds if the sender deleted the text field, and around 60 seconds if you stopped typing. A simple BGR test performed on two iPhone models running iOS 26 showed that the typing indicator would immediately disappear if the person typing deleted what they were writing. The indicator would remain for approximately 90 seconds even if the person typing stopped writing in the compose field after typing the first character.
Apple does not offer any figures regarding the behavior of the typing indicator. However, regardless of how long it takes for the typing indicator to disappear, iMessage users should not read too much into seeing the three flashing dots without a message immediately appearing.
