## What it is
An Android application for image super-resolution and upscaling built on NCNN and MNN inference engines, bundling models like RealSR, Real-ESRGAN, RealCUGAN, SRMD, Waifu2x, and Anime4K, plus classical interpolation methods. It ships as both a GUI APK and a command-line program usable from Termux.

## Use cases
- upscale photos on android
- enhance anime images with waifu2x
- run real-esrgan on phone
- super resolution app for android
- batch upscale images from gallery
- use super-resolution models from termux

## When to choose
- you want on-device image upscaling on Android without cloud services
- you need a CLI super-resolution tool runnable in Termux
- you want to try multiple SR models including custom ncnn/mnn models

## When to avoid
- you need GPU-accelerated desktop super-resolution (use the upstream ncnn-vulkan tools)
- you need iOS or desktop GUI support
- you require a permissively licensed dependency chain (license is non-standard)
