lack of timely support, wanted me to repurchase app

I bought this app several years ago and have used it often. It was my primary guide to bird identification in the continental US.

I recently tried to restore this purchase on a new iPad, but I get a message that I need to purchase it again. I like the app, but not enough to pay for it multiple times. I see others have had this issue too. After contacting customer support for this problem someone responded in about a week. Based on the slow response and the inability to use the app for which I have already paid for about a week, I rate it three star and would suggest others to be weary of purchasing it until they can resolve this issues that so many of have also experienced.

Customer Service at its best

When I got the notice I needed to purchase this app I initially went ballistic because I purchased it a long time ago and I had also received a notice that my iBird app from Mitch Waite group would no longer be upgraded and I would have to purchase a "new" app!
Here is the difference between the two companies. gWiz LLC went out of their way to help me. I received a personal email from customer service with a phone contact. They reset my information and even stayed on the phone until I was satisfied that everything was in working order.
The Mitch Waite group however, simply told me in an email that they needed to charge for upgrades because of the cost of maintaining their program. What they didn't explain was why they sell an apps at huge costs then stop upgrading them and bring the same apps under new names expecting us to pay for them again.
Kudos to gWiz LLC!!!

Best North American field guide

This app uses a “field guide” approach, depicting similar birds on one page. Birders stymied by fall warblers, for example, need only go to a single page to see 15 superficially similar species on a page. (I use an iPad mini and you need a good set of eyes for the smaller iPhones. You can download it for free for a 24-hour trial.)

Illustrations of similar species are excellent, such as the Myiarchus genus containing Ash-throated, Dusky-capped and Brown-crested flycatchers. Peterson, as well as the Sibley Birds app, portrays the subtle differences well; in contrast, iBird’s illustrations of these three are wildly inaccurate.

Unfortunately, recent AOU splits are not depicted: Pacific and Winter Wrens are still considered Winter Wren; Sagebrush and Bell’s Sparrow are still Sage Sparrow. Another shortcoming is having only one song/call although it is the most representative. There are good range maps, a link to similar species, and general info on the bird.

The developers are very responsive. After I complained by email of the frequent, annoying prompts to log-in they issued an update on Dec 15, 2017 which solved this problem.
