LeafByte measures leaf area and herbivory quickly and accurately. Take a picture of a leaf and a scale to measure total leaf area and leaf area consumed.

- Saves your data in a convenient spreadsheet on your phone or in Google Drive
- Analyzes leaves of almost any size or shape
- Uses freehand drawing to reconstruct missing leaf margins
- Can measure dark plant material (such as leaves) on a white background or light plant material (such as petals) on a dark background
- Reads and records all major barcodes
- Automatically corrects skew in photos taken at an angle

What’s New

Version 1.1.0

- Scale length is now recorded in data sheets
- No more accidentally swiping back from the drawing page
- Leaf marker is now drawn at the top of the leaf to avoid covering anything
- Undo now uses less memory on iPhone 5 and before

Wonderful app

I used this app to measure the area of hundreds of strawberry leaves, and it worked beautifully! With several people and I working on it, we got it done in a few hours using this app. To do this manually would have taken days. I couldn’t find any other apps that were free and this easy to use, so I would highly recommend LeafByte for measuring leaf area!
