Generally, I hardly ever write comments, but for this one, I'm writing right after downloading and using it for just a couple of minutes!
It's a helpful app with a clean and lovely UI. Furthermore, the colour space option is also excellent and straightforward. But there is some room for improvement.
The first and foremost is the resolution reduction issue. It reduces the resolution of the images without even asking. Personally, I prefer my photos to be in their original resolution and quality (even though it may result in a larger size because of the nature of the output format). It would be nice to have a setting for this.
The second issue I've experienced in this short-term app usage is the “Saving Behaviour” setting. It won't get saved permanently, and it gets reset to the default value on every launch.
It would be nice to consider these refinements.
Thanks.
