American Express is offering its US cardholders a FREE 6-Month Subscription to the Fluent Forever – language learning app for a limited time ($53.94 value). Membership automatically renews at the end of the six months. There’s no obligation, so you can cancel at any time before the free period is up and never get charged a dime. Offer ends April 15, 2021.

Fluent Forever is based on a recent scientific breakthrough called spaced repetition, which hacks your brain to naturally learn languages the way a child does. It is a system that doesn’t force you to memorize and doesn’t pound you with grammar rules and conjugation.
