I've put some up on HuggingFace: https://huggingface.co/datasets/appGoblin/app-store-app-desc... https://huggingface.co/datasets/appGoblin/play-and-apple-app...
As well as self-hosted (links require free account): https://appgoblin.info/free-app-datasets
I've also collected 100ks of man in the middle recording of HTTPs ad network, DSP, MMP etc signals across 100k+ apps for the past couple years. If anyone is interested please feel free to reach out. That data is free to browse on AppGoblin per app, though the body/json are not public.
