If you're a student on a budget but still want to learn a new language in your free time, Duolingo often has a Super Duolingo Student Plan available. You'll need to download the app in order to sign up for this particular plan, and it's important to note that it can come and go, so if you don't see it right away, check back often as it'll likely become available again.

You'll have to verify your student status for this plan and may need to re-verify every year in order to continue receiving the discounted price. Doing so means getting a year of the service for 50% less than the typical Individual price. Super Duolingo offers the same learning content as the free tier with the added benefits of unlimited hearts, skills practice, mistakes review, free challenge entry, and no ads to learn at your own pace without interruptions.
