The app is fully up and running right now, and you can use it to your heart's content. You will still be able to do multiple languages and use them as much as you like. We are not yet locking down languages, so feel free to explore as many of them as you would like to. Not all languages are released at this point, so there is a small difference in who's subscriptions start when:
Backers of IndieGoGo and Kickstarter: All backers have the option to choose when to activate their subscription. If you select to activate it, your subscription time will start and you can use all of the features in the app. If you do not wish to start the subscription, your subscription does not have to be activated until your target language or "learn any language" feature is released, and you can use the app until then to review what you have created before the option to activate subscriptions was available. You will not be able to create new cards until you activate the subscription.
Once we’ve released all planned languages and features including Learn Any Language then we’ll likely start up all subscriptions automatically. We’ll let all backers know long in advance of us doing this.
Multiple Languages Lifetime users and Single Language Lifetime users will all be automatically activated, as your time will never run out.
Retail Subscribers: Your subscription starts as soon as you choose one on the portal or in the App or Play store.
