Going on Ten Years!

I’ve lost track but I’d say it’s close to ten years now since I discovered this app. 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.)

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, making 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 (now closer to ten), 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!!!

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.

Still the best tool in my language-learning arsenal

The SRS system and the level of customization makes this a fantastic learning tool. I love that you can listen to vocabulary passively while walking around town with your earbuds in. It's too bad they phased out the lifetime purchase option. I've been using it for about a decade(?) and I honestly wouldn't keep using it if I had to pay monthly (in spite of how amazing it is!) because I'm poor...

One suggestion: please fix the problems with audio ducking in and out in the "listen" tool. I use this to learn Japanese, and the beginning of the word in the Japanese audio is always much softer than the end of the word, which makes it difficult to hear and understand new words I'm trying to study.

Other than that, I highly recommend this for language study or anything you want to memorize. Once you make the cards, the studying becomes easy and fun. You can easily create your own study system perfectly suited to your needs!

Developer Response ,

Hello Felicia,

Thank you for your feedback! If you have any question or issue, please contact us by using the "Let us know" button in the app. A few comments about managing decks:

1) If you accidentally delete a deck, it will move to the trash and you can restore it (Main screen of the app > My Decks > Trash)
2) If a deck is moved accidentally somewhere and you can't manually find it, try to use search to find its new location
3) Although you can rely on manual or device back-ups, the best practice is to use shared folders for important decks at least. The decks in shared folders are backed up on our server and on your other devices.
