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!!

Guys, I’m not kidding when I say this is probably the most amazing is the app I’ve ever used.
Please read my rant because it has a lot of useful information on it 😊
I literally deleted all my other apps for school just because they were useless compared to this app!!! This app is such an amazing thing, it allows you to play so many fun games using your vocab. I was worried that I would have to write all new vocab for the ones I already did and Quizlet but no! This app allows you to import your own study lists from other apps to. The only thing is it’s not free for all the games. BUT you can start your free trial which is what I did. The free trial lasts over a month and since school is out now for me I ended my free trial, but my mom saw how much I liked it and said she even considered getting the lifetime version. (Which is a great deal) If you are unsure about getting this app just know it’s definitely increased my grade!

Great app helping my kids learn


I homeschooled my daughter using Classical Conversations, which required a lot of memorization of facts. I love how I was able to easily add pictures by using the camera on my iPad, and how I could record the songs (that are used to memorize different facts) directly onto the card. My daughter begged to play the review games. I bought the upgrade, and for us, it was money well spent. The games are varied and kept my daughter interested enough so she could memorize her material.

Now I am in court reporting school and required to memorize a lot of information. I set the cards up so that they automatically flip and my hands never have to leave the stenograph. I am able to see immediately if I wrote the word correctly on my machine which helps reinforce the learning. I love that I can create a stack of cards and share them with my classmates. I recommend this app to all my school peers.
