Plants Identification Apps Review 

• Free Version: The basic application allows the user ten identifications per day after which the gallery can be explored only. The ads are annoying, frequent, and can be as long as 30 seconds.
• $2.99/month or $19.99/year: Premium version which has No advertisements, Unlimited daily snaps, 24/7 access to botanists, View every photo taken on the map, Access to PlantSnap on the web.

Pros:

• Identify 90% of all known species of plants and trees. 625,000+ plants in its searchable database.
• It is translated into 37 languages!
• Community Tab allows you to upload pictures of your plants and have other gardeners oohs and aahs over them.  It is fun to see all the pictures of uncommon flowers and plants discovered by fellow gardeners.
• Explore Tab allows you to zoom in to areas of interest and Arboretums, Botanical Gardens, Parks and Preserves in that area would appear along with visitors information.

Cons:

• The quality of the camera on your cellphone might make the identification inaccurate due to insufficient light or clarity
• The angle and distance of your pictures might also make identification difficult
• Weak or no cell signal would make this app not usable.

Star Rating:  I would give this a 4 Stars out of 5. I don't seem to take good pictures and the identifications are inaccurate probably 30% of the time.
