Can I see my Crop Map on my phone?

Yes, in the Heirloom mobile app, to look up your beds in the field. Pick a block in the row of tabs named after your blocks, pinch to zoom, and tap a planting to see its details.

On the phone the Crop Map is for looking only. Placing and moving plantings and printing are done in the web app on a computer.

The steps are in How the Crop Map works.
