Interesting concept. I like it!

It needs a higher resolution output on all the compositions that would benefit from it, like the square ones that defaults to 1500x1500. Possibly even the cropped ones(?).

This is just me being curious about the AI/machine learning stuff...If it’s powered by learning algorithms, does it not need to be updated on a semi-regular basis to benefit from the learning “AI”? I know my desktop photo apps have all been updated with “AI, machine learning” etc. I’m slightly confused by these terms as the apps are not actively learning anything, nor is this app.

Anyway, great concept, gives you new perspectives for sure, and new ideas.

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.
