Three more things WhatsApp and Signal don't have

Screenshots and recording

In the app, the other person can't take a screenshot or record the screen. On iPhone they can ask for one-time permission, and attempts without it show up in the chat. On Android both are blocked entirely. The browser version doesn't have this protection.

Debt ledger

Log a debt from the chat. Once the other person approves, the record is locked and can't be deleted. TL, EUR, USD and CZK.

Shared tasks

Put a date on something you both need to do. Drop reminds you the day before and on the day.

WhatsApp and Signal were checked against their official help pages on 15 September 2026. WhatsApp usernames are rolling out gradually, screenshots are blocked only for view-once media, and translation works on some devices and languages. How data is handled is described in the privacy policy.
