What Is Evapotrack?

Evapotrack is a plant watering tracker for iPhone and iPad (Android coming soon). It measures water input and runoff to calculate how much water your plants actually retain. Built for drain-to-waste growers running coco, soil, or any medium where tracking runoff matters. Log each watering, monitor retention and capacity over time, and get a data-driven suggested amount for your next watering — all offline, all stored locally on your device.

Not sure how much water your medium holds?
