So technically you do not need a subscription to use a pronunciation trainer, you could buy one of our trainers from the website and load it into Anki to use independent of the app itself.
When the app is released, you can purchase a subscription. You'll get access to our trainers with your subscription. You should be able to finish it within a month, so you'll only need to pay for a single month, which is actually cheaper than our existing trainer prices.
Hey, that's why you've got us.
If you have any questions, let us know.
