POLARR PHOTO EDITOR

From polarr.com Available on Mac, iOS, iPadOS, online Polarr is more of a filter app than an editor, enabling you to adjust various properties – color, light, lens, curves, and so on – and to apply interesting and eye-popping color filters. There’s a paid-for version with more tools and better layer handling, but the core set in the free version is impressive and the interface is easy to use. If you’re looking to do more than Photos can do, it’s worth downloading.
