Where is the option to turn off the AI Crop feature??

This app is very good at revealing photos I had completely forgotten about. However, I cannot give this app 5 stars due to the fact that there is not an option to turn off the AI Auto Crop Feature. I love seeing these old photos again but would prefer to save them to photo albums in their original format. Your Polar Pro App provides me plenty of opportunity and tools to crop them when and/or if I want and how I want.
Add an option to re-save my photos in their original format and I will more than likely use this app daily. Unfortunately, I’m going to have to shelve this app until said feature is implemented.

Update offers a terrible “improved” interface

What a disappointing upgrade. I really object to developers (Apple included) telling me how I should best file, review, sort and display my images. Give me a simple image picker and just display the results of your “deep dive” cropping algorithms. I have 2000 images on my iPad Pro and It takes forever to find anything with this random memories interface. I gave up trying. And what does “Remove” do? And what is with the thick black lines covering what looks like multiple cropped images stacked on top of each other? And so much wasted screen space. I’m sorry, this is just a mess, and the only reason it is staying on my iPad is in hopes of a major redo someday, because sadly it will not see any use before until then.

Interesting idea; crashes often

I wanted to give it a higher rating because the app presents interesting crop ideas that I didn’t think of in many occasions. However, the app itself is not stable. It crashes often, but seems to happen randomly. It could be pressing the crop again button, scrolling through the styles, or simply trying to save the new crop into the camera roll.

Developer Response ,

Thanks for the feedback, we have an update coming out in a few days that improves stability. Let us know how it goes for you.
