Features
Authentication: Passcode authentication is enabled which is needed to unlock hidden and locked chats. If your device supports fingerprint authentication, then you can use it as well.
End-To-End Encryption: Your messages are encrypted right from the moment you send it. This makes sure that only the recipient receives the message and NO ONE ELSE.
Hide Chats: You can hide chats to protect against prying eyes. YOU will have to authorize to unhide the chats.
Lock Chats: Hidden chats not secure enough? Lock individual chats which only open after YOU have authorized it.
End Conversations: Once you're done with a conversation, you can choose to end it, by swiping your friend's message from left to right. Doing so will delete all the conversation up until that message.
Save messages: Double tap on any message to save it locally. Saved messages can be viewed by swiping right to left on the chat screen.
No pesky notifications: We do not believe in keeping users addicted to our app by frequent notifications. Chat when you feel like it. We do not bother you with notifications.
No forwarding: Enigma is developed to be an intimate one-to-one chat application. There's no option for forwarding messages. Hence no fake news.
Beautiful, minimal UI: The UI is uncluttered and beautiful. Gestures are used to make it pragmatic instead of using additional screen space.
Less than 10 MB: All the above features are tucked under a measely < 10 MB APK Size.
