Top 4 Free Secret Texting App for iPhone in 2021

Texting is one of the most common ways of communication. It is easy, fast and convenient. However, short message service (SMS), the most common method of texting, is not as secure as you think. SMS messages, which are sent and stored on servers in plain text, can be intercepted during transit. You may text with friends, colleagues or business partners. There may be private information or important commercial information in the text messages.

To secure your privacy and text messages, you can hide your messages with a secret texting app. Unlike SMS services, secret texting apps can encrypt text messages, photos, videos and chats by end-to-end encryption. The messages are encrypted on the senders’ devices, transmitted in an unreadable encrypted format and then decoded on the intended recipients’ devices. It can prevent third parties, even the company that runs the messaging app, from accessing the messages during transmitting. Different from traditional SMS, it is always free to send messages with hidden text apps. Another advantage of hidden text apps is that they can be disguised as a news reader, photo album, game app or even calculator.
