I've been using Signal and Teleguard, but not Threema because it's a paid app. Which one is the most secure?

This depends on your scenario.
You can use a comparison chart to find suitable fits.

Threema and Signal are both ok, Teleguard in general doesn't look like a trustworthy option.

    Yes, Signal and Threema have great encryption, and Teleguard is not as popular but it is anonymous and from Switzerland.

    It's mainly about Teleguard apparently being completely closed source and using an unknown proprietary encryption protocol.
    Personally I would omit it based on this and use it only for non-sensitive stuff if completely omitting were not possible.

    Yes, Teleguard is not particularly reliable, even though it is owned by Swisscows, a company that has its own search engine and secure alternatives to Google. Furthermore, Teleguard is not that old; it was launched in 2021.
