About this app
Unmark lets you paint over a watermark, logo, or unwanted object in a photo and erase it, entirely on your phone, with no internet connection required and nothing uploaded anywhere. Watermark removal uses a small, pure-Kotlin nearest-fill and smoothing algorithm. There is no AI/ML model, no bundled weights, and no native code. See the project README for how it works.

Removed automatic vendor watermark detection, it was unreliable. Batch process now works by drawing one watermark box on a preview photo and reusing it across the whole batch, instead of guessing a vendor's watermark position.
