I've had good speed / reliability with TheBloke/rocket-3B-GGUF on Huggingface, the Q2_K model. I'm sure there are better models out there now, though.

It takes ~8-10 seconds to process an image on my M2 Macbook, so not quite quick enough to run on phones yet, but the accuracy of the output has been quite good.
