Android + OpenCL implementation — monocular depth on-device on non-flagship phones (Adreno 6xx)

Hi! I wanted to share an Android + OpenCL implementation of Depth-Anything-V2-Small, in case anyone wants to run it on a phone:
- Try it: Edgi on Google Play — runs fully on-device, no cloud.
- Open source: the app is built on top of the open-source adreno-llms inference engine — https://github.com/a8nova/adreno-llms — pure C++/OpenCL with hand-written kernels tuned for Adreno.
It's tuned and tested on Adreno 6xx GPUs — the GPU class in mid-range and older Android phones (verified on a 2020 Motorola Razr / Adreno 620) — and should run on most arm64 Android phones with OpenCL, though the optimizations are Adreno-specific. On the Adreno 620 it produces a full depth map at 518×686 fp16 in ~5.2 s/frame, with cosine 0.99999 vs the PyTorch reference.
Hope it's useful — happy to answer questions!
