About Easy Leaf Area Free
Easy Leaf Area Free 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.

This looked like just the clever solution I needed to estimate the area of broken solar cells with irregular shapes. However, my cells are blue and your app is optimised for green. You do say that it only works for green but could you please consider making a version for blue objects too? Well done on your nice leaf measurer!

Good job. It might become more powerful it it has load from gallery, export or save results as images, and unit conversion...BTW I read your paper on Application in plant sciences, how about the prospective for tomatoes leaves so far? Thanks

This app worked the first day I used it, but now on day two any photo I take doesn't show up. The stock photo just stays there, so I can't do anything with it.
