Not really my idea, but a feature I found cool when using N26 bank App before I closed their account (they are bad btw).
With bunq you can hide figures concerning your accounts totals by tapping the eye icon, which is cool.
Why not implementing the same feature but triggered instead from specific movement of hand/fingers on the front facing Face ID camera ?
I guess it can be implemented with iOS App on Face ID featured devices only and some of the Android friends.
- option to turn on the gesture hide/reveal figures
- swipe one... two fingers in proximity of the Face ID camera to hide / reveal figures.
Just a neat Face ID cameras implementation :)
