best free apps for sexting

1. Kaboom

Kaboom promises to give you control over what you share online, where you share it, and how long it lives.
As a service that doesn't require the recipient to also have the app, creating a Kaboom message generates an HTTPS-protected web address that will work through SMS, email, WhatsApp, Facebook Messenger, etc.
You can select how long you'd like the message to stay online, e.g., 30 seconds, 10 minutes or 1 day, or how many times the message can be viewed before it self destructs.
From privacy experts AnchorFree, the creators of Hotspot Shield, Kaboom is a clean, simple app that you can trust.

2. Confide

The Confide app helps you to "communicate digitally with the same level of privacy and security as the spoken word."
This confidential messenger service works with iMessage, texts, photos, documents and voice messages, boasting end-to-end encryption and disappearing messages.
Confide's main selling point is screenshot protection with special technology meaning that screenshots are captured as grey blur on most platforms.
In addition, only a section of the message is revealed at a time, the sender's name is never visible from the message view and if a screenshot is attempted, the recipient is ejected from the message and the sender alerted.

3. Sobrr

With the philosophy of living "life in the moment," Sobrr lets you message and post to group chats with all content automatically expiring after 24 hours.
Although it doesn't offer screenshot protection, Sobrr promises to "make sure there is no evidence of your craziness" as individual messages and photos can be viewed only once.
One unique angle of Sobrr is that "friendships" also only last 24 hours, unless both sides choose to keep each other in their "Crew."

4. Wickr

Currently handling billions of messages in almost every country in the world, Wickr claims to be used by "world leaders, executives, journalists, human rights activists, celebrities and your closest friends."
It offers end-to-end encryption for text, photos, picture and voice messages — all with a configurable time to set the content to expire. Meanwhile the "Shredder" functionality irreversibly removes all deleted messages and media from your iPhone.
You can group chat with up to 10 others from your private address book. On the light-hearted side of things, there are stickers, graffiti and photo filters.

5. Dust

Dust, also known as "Cyber Dust" as per the slightly dated demo video above (the design has since been updated), offers "heavily" encrypted messaging not accessible by anyone.
All messages and content sent via the services are automatically turned into "dust" after 24 hours. If you want a more immediate expiration of messages, you can set content to delete as soon as it's been opened and read.
Finally, there is protection against screenshots with no names displayed in private chat rooms. In addition, Dust will notify you if a screenshot has been grabbed.
