Signal vs QKSMS

Signal uses an advanced end to end encryption protocol that provides privacy for every message every time.

Signal is free and open source software, enabling anyone to verify its security by auditing the code. It's the only private messenger that uses open source, peer-reviewed cryptographic protocols to keep your messages safe.

Edward Snowden uses this messenger and recommends it to everyone who is concerned about his privacy.

Signal can be your default SMS/MMS text messenger. Encryption is not possible when sending SMS to your contacts, however.

Signal Desktop is a Chrome extension that allows you to mirror messages from your phone, including replying.

You can easily view all media shared in the chat without scrolling back to when it was shared.

Users can set different notification settings per user as an easy way to know who is messaging without having to look at the actual message.

There are light and dark themes available within the settings which can be switched depending on how light it is around one when using the app. The dark theme can also help to conserve battery when being used as not as much brightness and hence battery will be used.

Responsive, highly customizable Material Design interface makes for a native looking app that fits in well with Google's UI design guidelines.

Through delayed messaging one can set it up so that a message is not sent automatically. This can help for those times that it may be best to think something over before sending out a rash message.

While QKSMS is one of the younger apps, the developer is quickly adding features/fixing bugs.

Those that own an Android Wear device will be able to set it to receive their messages on the Android Wear device making for convenient notifications and easy messaging through not having to take their phone out.
