Frequently asked
Quick help for learning and purchases.
What can I use for free?
You can study a 50-word sample across five business topics and try the learning and practice flow. The lifetime purchase unlocks the full vocabulary collection and unlimited Part 5 practice.
Does studying need an internet connection?
Lessons, saved progress, and on-device pronunciation are designed to work offline after installation. Buying or restoring the lifetime unlock needs a connection to the App Store and the purchase service.
How do I restore my lifetime purchase?
In the app, open Settings and tap Restore purchases, or use Restore on the purchase screen. Connect to the internet and use the same Apple Account that made the purchase. If access does not return, email us with a description of the problem. Please do not send payment card details.
Is the lifetime unlock a subscription?
No. It is a one-time in-app purchase. The App Store shows the price in your region before you confirm payment.
Will reinstalling recover my learning progress?
Study progress and settings are stored on your device. Deleting the app may remove them; we do not have an account or cloud copy to restore. Restoring a purchase recovers eligible paid access, not your study history.
