SUPPORTS UP TO iOS 13.3.1 only
Chatlock locks your important conversations with the most beautiful way ever! Like it’s integrated within iOS natively !
All you have to do is swipe on the chat cell you want to lock and new button is added there called lock once pressed that conversation is locked no matter where you access the conversation either from lockscreen, notifications, inside the app you need to provide your FaceID/Fingerprint to unlock that chat.
You have the option also to take front picture when the credentials are wrong ;) Very useful for annoying GFs and parents.
Chatlock currently supports SMS,Twitter,Whatsapp and Instagram. I plan to add support for facebook messenger.
Here's a small glimpse of the tweak in action:
There is a report button in the tweak’s prefs use it you case you want to report a bug or a request 😁
Face ID devices may cause crashes i attached a video in settings preferences showing how to fix :) Blame apple for that not me :p
Compatible with iOS 11,12 and 13
Supports A12 devices also.
