Hi all, if anyone is interested, we have built a web app that I think may be useful for at least the journal/record keeping aspects that people have discussed here. It's not strictly permaculture focused but it uses satellite imagery and allows you to use your own map image if you have access to a drone.
This app can be used on your phone or tablet whilst in the garden to record locations, dates, activities, observations, photos and weather information like rainfall and frost dates.
There is lots in the pipeline (planting calendars, companion planting, integration with the Netatmo weather station and the Edyn soil sensor and much more) but it is very usable as is and over the last several years there has barely been a day when I haven't used it myself in my own garden.
If anyone is interested, feel free to check it out at www.planmy.garden, you can start a 14 day trial for free. We would love to hear what you think.
