Easy Leaf Area

About this app

Easy Leaf Area measures leaf area non destructively in seconds. Place a 4 cm^2 red piece of paper next to your leaf and take a picture. Make sure your leaf and scale are in the same plane and are parallel to your android device. Leaf area is calculated automatically from green leaf and red scale areas. Adjust the sliders to correctly identify green leaf and red scale areas.

Important Considerations
Easy Leaf Area Free measures projected leaf area. Camera angle, lens distortion, leaf angle, and leaf overlap can result in inaccurate leaf area measurement. You can use a 4 cm^2 green piece of paper to calibrate your camera set up. Non-green leaves or portions of leaf are not measured with Easy Leaf Area.

Ratings and reviews

I don't often write reviews but this soft is definitely worth it! I use the computer version to analyze Arabidopsis rosette areas and it works like a charm!!! Definitely will cite your paper! Thank you for developing!!!

Not correct. Very poor and wrong reading. I've measured the same leaf four times and the readings are; 74.59, 91.13, 108.00, 111.83. Not useful at all

It seems a great app. Need to test it more. I qas wondering can it be used on large canopies i.e eggplants, tomatoes? If yes where should the red paper be placed? On the top or bottom of the canopy?
