I built a maintenance tracking app that I can use for household/garden tasks. I had a problem where things like replacing a battery for a chicken coop, I'd be a month late on replacing it and I had it in my calendar to replace every august, so I'd be replacing it early every year. And I also had in my calendar to fertilize my hop plants every 2 weeks, which meant in January I'd get a calendar event to fertilize my hop plants.
And sometimes my wife wonders what we have to do (especially in spring) for gardening, planting, chickens, etc.
