The Fluent Forever trainers will only work with the original Anki program, which is free and can be downloaded here:
If you’re having trouble getting the trainers to work on your phone, we recommend downloading them first to your computer to “unzip” or “decompress” the files so that your phone can use them. (This process is super easy for computers to do, but phones can struggle a little with it.)
(And if you’re struggling with the unzipping process at all, we have a great article HERE with loads of instructions to get you on your way.)
Note: As of September 12th 2019, we no longer provide official support for our Anki based pronunciation trainers and word lists. You are more than welcome to still purchase and use them, but the support we are able to offer for these products is limited. For supported languages, these materials are already built into the Fluent Forever app.
