No relations to them, but I've started using Happy[0]'s iOS app to start and continue Claude Code sessions on my iPhone. It allows me to run sessions on a custom environment, like a machine with a GPU to train models
This seems to be the only solution still if using bedrock or direct API access instead of Pro / Max plan, the Claude Code for Web doesn't seem to let you use it that way.
You can log in to your CC instance however you like, including via Pro/Max. Happy just wraps it and provides remote access with a much better UI than using a phone-based terminal app.
