LeafByte

Scale isn’t working on my end and not able to calculate surface area. I am able to calculate percent herbivory though.

If anyone has spent countless hours using software like ImageJ, this will make your life a lot easier. A great app to use in the field or after collections have been made. It has made my research project a lot more efficient! Easy to use, straight to the point, and all the better that it directly saves your data to Google Drive. My only issue was after using it for a large sample size it began to close the app after adding a new sample, but the data double saved on my Google Sheets document so no information was ever lost. Perhaps just a small bug from over-usage since the app is relatively new! But overall a great app!!

Disclaimer: I know the developers of this app. Compared to other methods of measuring herbivory (ie, manual: grid method), I find this method faster. I am also more confident that it is accurate and less prone to user error. It also quickly collects several metrics (total leaf area, % damage) that I previously did not calculate due to labor constraints, but that is very useful information to have. I love that the data is automatically entered into a spreadsheet and that leaf images are saved!

Love this app for lab work! Makes everything so easy and quick.

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!
