Hi, we discussed this now and have some questions/feedback.
Most importantly, we’re not in a position to sponsor the development. In the context of Grafana this project would have to be open source and community driven. Before kicking this off though, I would encourage you to write up a roadmap that also clarifies your long-term commitment. We have no native iOS expertise, this would have to be entirely you, plus engaging the community and responding to issues+PRs.
As for the features you would like to see, it’s worth exploring if they couldn’t be done in a (mobile-optimized) progressive web app instead of a native app. Perhaps that could be a way to contribute in a slightly smaller, but still big, way, that would bring the features that you want.
Hope that helps.
