Have you tried Photopea? It’s a free web app that’s a dead-ringer for Photoshop, and has a pretty decent responsive mobile interface. If you’re looking for a Photoshop-like experience on your phone, it’s probably your best bet.

Honestly, using https://wefwef.app as a web app is hard to beat right now. It works very smoothly, and I finally understand why all the iOS users mourn the loss of Apollo so hard. Granted, using an iOS-esque interface on an Android device is a bit odd, but the gestures and the layout are just chef’s kiss.

The biggest issue with it is that it’s getting hammered on the primary domain, so I’ll probably move to self-host it sooner than later.
