Hi there reddit folks , check out my unique app that adds secure text and image-encryption to any other app as an overlay.
Encryption for all Android apps with OVERSEC
Oversec is an overlay on top of other apps that transparently decrypts text it finds on the screen, in place.
I call this Eye-To-Eye encryption!
Have a look at the demo video to see how it works:
Better than simple integrated End-To-End Encryption, Oversec decrypts and shows private messages only when they're on the screen – nothing is ever saved to disk!
Oversec allows true private chats via Whatsapp, SnapChat or any other chat app. Oversec also allows easy PGP encrypted emails using Gmail, or other email apps.
For the ultimate privacy, I've added a unique feature -- decoy encoding:
Encrypted messages are encoded and hidden inside innocuous regular text (by encoding them as zero-width unicode characters), and the decrypted secret content is only available when Oversec is active. Users can write their own decoy texts or select from a range of included generic messages.
Oversec can also encrypt photos and images which can be sent via chat or email, or saved for personal use.
Oversec uses either a strong symmetric cipher (ChaCha20+Poly1305) or asymmetric public key PGP encryption (via OpenKeychain)

Oversec encryption app, works with most text based apps, kinda hard to explain how it works. But it's freaking useful and cool.
There's oversec for Android https://play.google.com/store/apps/details?id=io.oversec.one which is also open source. But both parties should have it installed
