Virginia Tech Tree Identification brings the award winning Virginia Tech digital dendrology material to your iPhone. It contains fact sheets for 969 woody plants from all over North America with an in-depth description, range map and thousands of color images of leaves, flowers, fruit, twigs, bark and form. Users can narrow the species list for any location in North America using the phone's GPS or any entered address or zip code. Basically the application can become "The Woody Plants of Where You Are Standing." For example, it can become "The Woody Plants of Southwestern Oregon," "The Woody Plants of Central Park," or "The Woody Plants of 37.108 lat., -80.452 long., elevation 2118." Users can further narrow the species list by answering a series of very simple tree attribute questions such as where the plant is growing, leaf shape, leaf arrangement, flower color or fruit type. The species list can also be narrowed by typing a keyword such as oak, Abies, red or palm. For example, if "oak" is typed, only oaks found in the defined area will be listed. A feature also allows you to send any tree related question to "Dr. Dendro," a tree expert in the Department of Forest Resources and Environmental Conservation at Virginia Tech. You can send a tree description or pictures of your plant and experts will help with identification.

Verdict

The call

The clearest difference is monetization model: Purdue Tree Doctor at free against vTree's paid. Purdue Tree Doctor also leads on review sentiment (57% vs 37%) and update cadence (every 4 months vs every 11 months). vTree's advantage is rating (3.3 vs 3.0) and ratings volume (46 vs 11). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

vTree holds the better App Store score, 3.3 against 3.0. Both are backed by a comparable volume of ratings — 11 and 46 respectively. Written reviews complicate that: 57% of Purdue Tree Doctor's written reviews are positive against 37% of vTree's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Purdue Tree Doctor ships an update every 4 months, vTree every 11 months. The most recent releases landed on October 2, 2026 and October 11, 2026 respectively.
