Samsung: Long-exposure 𝘦𝘧𝘧𝘦𝘤𝘵 (not simply pro mode) from motion/live photos?

Ahoy all,

I know Samsung's phones don't do it natively (apart from using the actual shutter settings in pro mode), but does anybody know if there's an app that can emulate the iPhone's live photo long exposure effect (as seen here), using Samsung's motion photo function?

On the iPhone, you can open any live photo, then tap a menu option to have it stack each frame to create a long-exposure effect.

Blows my mind that Samsung hasn't dived into this type of thing, especially considering the Pixel now also has some great post-processing motion effects

Cheers!
