Sly (Image Editor)

★★★☆☆

Simple, friendly image editor that doesn’t need any extra permissions, it just lets you adjust your photos! It’s not elaborate, just basic adjustments like cropping, changing contrast or saturation, sharpening or noise reduction. Feels more suited for mobile, but has a Linux version as well as Android. There are only two features I miss when using it on my phone:

• It doesn’t show up as a target app yet for opening images, either on Linux or on Android.
• You can only rotate by right angles, so you can’t fix a shot that’s skewed.

One bug is, for me, a showstopper: While there’s an option to save EXIF metadata, it doesn’t seem to work. I always want to keep the original timestamp, and my main use case for an easy photo editor on my phone is to be able to quickly crop a photo to upload for iNaturalist or MapComplete, in which case I want to keep the location too.

For now I’m using Image Toolbox, which is slightly more awkward. If and when Sly implements the share target and fixes the metadata bug, it’ll a whole lot more streamlined for this flow!
