Customer Reviews

fix for installing hangup

I had the instsalling hangup for this app (& also Butterflies). I figured that since it got some good reviews it must work for some people so the problem likely had something to do with the setup of my iPhone,. I took it to the Genius Bar and they held my hand & walked me through a reset (to change all settings bacck to default). This does not touch the data on the phone, just the settings (wallpaper, ringtones, alarm tones, etc). Now the app works fine. (One more note, before you muck with your phone you should do a backup.) My only complaint is that Green Mountain Digital could have and should have told all of us how to fix this a long time ago.
The Audubon apps are great.

Limited Coverage and Hard to Use for Identification

I tired this app out on a trip to the Sonoran Desert. The coverage there is very limited, it is very slow to use, and comparisons are difficult. All the trees I couldn't identify to genus were not in the manual. The tree that was in flower everywhere was Parkinsonia microphylla (foothill paloverde). It is depicted in a single picture 2 inches square that cannot be expanded and shows only the form of growth and the fact that it has yellow flowers. One cannot tell the size of the flowers, the number of petals, etc. I was not able to determine what is searched for search terms, but it appears you cannot search for family names, e.g. Compositae or Composite, and searches for vernacular family names present odd results, e.g. pines when searching for "Pea".

App doesn't update correctly

While this app used to work fine, the most recent update that I downloaded has made this app unusable. I reported the problem to Green Mountain via a helpdesk email. A week after doing that still no one has gotten back to me. I recontacted them, still no answers! Disappointing when this is a paid app. While the app did reappear as something to update via a download, nothing changed. It still shows "installing" and is unusable after numerous sync attempts.
