Potential is there

*** Update, customer service is spectacular! They reached out right away to address the below issue. Long story short the issue is with apple’s newest iOS update, and not the app itself. They are working on a fix, but it will take some time. I appreciate their prompt reply and willingness to find out what the issue is. ***

The potential is there for this to be great a flashcard app. I downloaded the app to make flashcards for my son‘s science test. I wanted something basic that I could quickly make flashcards instead of having to write them out manually. The first 10 flashcards were great I use the microphone function to read/speak the information onto the flashcards. However, after that the microphone function stopped working. I tested the microphone and other apps and it worked fine I restarted my phone and the microphone started working again, but only for one card. Tried restarting the phone again, and again the microphone worked but only for one card. I would give it five stars if the microphone allowed me to read/speak instead of having to type the information into the card, which is too time consuming.

Developer Response ,

Please update the app. The microphone is now working properly.

Powerful tool

This is the single most powerful language learning tool I have on my phone. It puts me in the driver’s seat, allowing ME to choose what words, phrases and grammar patterns are right for me at my current level of learning, providing accurate pronunciations for vocabulary I provide, in the language of my choice. (I use Japanese, Chinese, Vietnamese, Korea and Spanish and have found the pronunciation surprisingly accurate.) And it allows the addition of photographs and drawings to replace words, making possible a more direct association where appropriate. The ability to organize by language, learning objective, level of mastery or any other way imaginable is also invaluable, Maki g it possible to focus on a small group of words or target phrases and then move them to a different file of already mastered items for later review. Brilliantly conceived, and the user interface is also excellent. Job well done!

After more than six years running, still my main gun!! I use it for four different languages. Love it! Have even used it as a teacher as well as student. Still
Love it. Job well done!!!

I am a college student who has used this app for over two years and I have always loved it. Today I a question and so I emailed them not excepting to hear back from them for at least a few hours. To my amazingly surprised eyes I had an instant emailed response with help and continued help till the situation was resolved enough for me to continue with what I needed to get done with my work. The customer service and level of help this app provides is absolutely fabulous. I am one who NEVER writes feedback, and I usually don’t email for customer support either but I was just so frustrated today and I am so pleased right now. Just wow! With all the stress of being a student it is so nice to have wonderful apps that will let you study and help you learn a certain way by matching vocab, and in college there is so much. Or play games with questions before bed or before a big test, its less stressful than just reading notes.

Again cannot say enough about this app! Love it!!
