Ratings and Reviews

Not good


You have to know the disease or look up every disease listed. No option to describe problem, (i.e. Brown leaves, needles falling, etc.) Don't waste your time or money.

Very useful app!


This app is very useful for anyone who works with trees, or owns trees. It is extremely easy to use, with minimal clicking around needed to find things. The photos are excellent, and clearly illustrate symptoms. Best option is that the app is set up to easily allow the user to save or share the photos with others by email.

This app is a Must Have for arborists, landscapers, garden centers, and Master Gardeners. Extension agents/educators would find this a handy tool. Landowners with numerous landscape or woodlot trees would benefit from having this app. Can be used out in the wild where cell signals don't exist, although you'll need to wait until you get back to civilization to reach the provided links.

Highly recommended.

Great reference & Very convenient.

I am a college graduate and have been in the plant health care industry for over 10 years. I was pleasantly surprised with the intuitive format and impressed with how many different pests/ woody species were available for reference. Each disorder is well defined along with decent photos and key ID bullet points for quick reference. This is not a learning tool for novice horticulturist. If you cannot ID plants, this app may not be for you. For any professionals, botany/ plant pathology students, arborist, urban foresters, nurserymen, golf course superintendents, or PHC salespeople -
This is an great horticultural reference application for only $2.00!
