I’ve been using FlashFacts on my Mac for a year, and have recently been syncing it to my iphone. This app works great for me, and I believe it has been a large component of my success on my nursing school tests. My husband is in school, too, and he has purchased the app on his Mac and iphone, and likes it. I love that I can toggle back and forth between cards by using the “Command" & arrow keys, as it saves a lot of time. Anytime I’ve had questions or problems, Tyler has always responded quickly to my e-mails. The new upgrade (1.9) was a little scary, as for a moment I thought I had lost my flashcards when trying to set up the icloud automatic syncing option. Tyler came to the rescue within minutes of me sending an e-mail, and walked me through how to get everything working properly—and it is working more efficient than before. Love the new on-line option, too, because that means I can use my flashcards on my iPad. Thanks so much!
