What’s New

Version 2.1.1

Hey everyone! Thanks so much for your continued support of the project. This small update fixes a critical bug with iOS 14 where the button to return to the filter list would not be shown (caused by an issue with navigation items in UIHostingController).


- Added support emails to the app for easier reporting of issues
- On compact screens, the filter list now shows automatically on first app launch
- Navigation buttons are now bigger and include the correct padding so they're easier to tap

Thank you so much for supporting the project, and don’t hesitate to reach out via email or Twitter if you have suggestions or issues!

Neat idea

Update: Thanks for the quick reply, yet so friendly and informative! Had to come back to give 5 stars, this app is in good hands.

I like the idea of this app. Sadly it doesn’t meet all my needs. So a few suggestions!

Sample images showing what each filter looks like would be great. It’s much too inefficient to tap through each one and select an image and guess at what the inputs should be. I almost never know what filter to use lol so being able to look through them all with the sample images was super useful with the core image filter reference doc.

Can the image preview be built native? The way zoomed out web page makes me sad.

I don’t think CIEdgeWork is working. All the values I try shows a white image.

Developer Response ,

Hi there! Thanks so much for the review and feedback, it's really useful! I love the idea of sample images showing each filter.

Sample images are available for many filters on, but there's no reason they shouldn't be in the app as well. I've opened to track this work.

The image preview is actually native, but the scroll view UI is so bad that it makes it look like a web page. I have an issue here to track the work of rewriting this view to be more phone-accessible with SwiftUI:

And thank you for the report about CIEdgeWork! I'll look into it. I've ticketed it here:

Thanks again, and I hope that after these improvements the app will be more usable for your use case. Cheers!

Very useful!!!

This saved me more than $5 worth of time, so thank you for making this.

As other reviewers have mentioned, I think what could use some love is the “Try it” screen since it’s a bit unintuitive and depending on the size of the image I provide, I find myself having to pinch and zoom to enter the parameters and then adjusting again to see the results more than I’d like.

Lovely tool to have! I was definitely confused about the “try it” view being scrollable and zoomable though. It’s pretty hard to tell what’s going on when you first use the app. It’d be nice to see the options fit on a iPhone screen in the next version!
