Users collect or submit photographs of diseased plant organs and calculate the percentage of diseased tissue. Through a user’s touching of the device screen, the algorithm employs user-specified values for up to eight colors of healthy tissues in the photograph. The color of each pixel is then evaluated for its distance from the healthy colors and assigned a status of either healthy or diseased. Users may slide a threshold bar until satisfied that diseased tissues are represented accurately before the percentage calculation. The assessment data and photographs may be sent by e-mail to any recipients. Instructions for using the app are provided on the About screen. The Leaf Doctor was produced by the University of Hawaii at Manoa, College of Tropical Agriculture and Human Resources. ## Leaf Doctor Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple128/v4/e4/61/40/e4614012-d72a-1db4-def4-20d34ecb0656/mzl.adhwsaei.png/640x1136.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple118/v4/80/15/b7/8015b755-1dde-e70b-85c2-56ab956fd49c/mzl.opvtoudq.png/640x1136.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple118/v4/0b/dd/e0/0bdde0f8-d550-861c-5f51-e845d5ded6d8/mzl.qpqcinvr.png/640x1136.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/Purple118/v4/5c/b8/1e/5cb81ec2-696b-f706-e1ae-7c9e6d0fb74d/mzl.tqxekfxc.png/640x1136.png) ## Leaf Doctor Rating Breakdown in United States - 5 stars: 4 (17%) - 4 stars: 1 (4%) - 3 stars: 1 (4%) - 2 stars: 1 (4%) - 1 stars: 16 (70%) ## Leaf Doctor Reviews in United States ### ****- "Useful for Ag professionals" This app is helpful for quickly quantifying the severity of disease lesions on plant tissue for use in determining treatment thresholds. -- b.leevr, 2025-12-10 ### *---- "Doesn’t work" The app tells me everything is healthy. No matter the threshold, no matter the plant. Some of the plants I KNOW are sick. App doesn’t work. -- Jennifer415, 2022-10-13 ### ***** "Read the description folks" If you want a diagnosis and assistance with control, see your local county extension agent. If you need to quantify the % leaf area containing lesions using an iPad then use this. Glad this is available. I am going to try it out and see if it can assist technicians with conducting ratings. -- researchrenegade, 2022-06-09 ### ***-- "My Aloe plant" There is something wrong with my Aloe and I figured that this app could tell me what was wrong with it and how to fix it. Instead, it told me that my plant was healthy when it obviously is not. -- lori21929, 2022-05-03 ### *---- "Who can read the instructions" Why are the instructions in grey? They are small font and hard to read. At least, if they were in black I could read them. -- Regulus250, 2021-01-31 ### *---- "Take a leaf sample to your local nursery instead" Now I know my leaf samples are 79% diseased with some mystery illness, LOL. Why is this even in the App Store?!?! -- Want a refund now........, 2020-02-15 ### *---- "No help. Worthless" Says the my plant is diseased. That I knew. Now tell me what it is and what i can do about it. -- rhren, 2020-02-02 ### *---- "Photo of a dead leaf=healthy" Doesn't work -- Mcdroid, 2019-05-18 ### **--- "Didn’t help with diagnosis" Now I know that my tomato leaf is 49% diseased with a mystery illness. -- Liddi1234, 2018-06-07 [View all Leaf Doctor reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Leaf Doctor Discovered Keywords -
