When it comes to learning a new language, Duolingo isn't the only app on the market. Many people have turned to Ling. The reason is probably simpler than you think!
Duolingo doesn't offer the language you need
Duolingo is a popular way to learn more than 40 languages. That number seems large, and it includes many of the world's most widely spoken languages.
However, there are still thousands of languages out there, and Duolingo doesn't even cover the 40 most popular languages. For example, you want to learn Telugu, one of the main native languages of India and among the top 20 most popular languages in terms of number of native speakers. Most Telugu speakers probably live in India, but Telugu is one of the fastest growing languages in the United States.
That's how people discovered Ling as an alternative to Duolingo. Ling helps you learn Telugu. Like Duolingo, Ling also offers more than 40 languages, but includes more Asian and Eastern European languages than its competitors.

Ling has a much cheaper option
If you're willing to stick with Ling, it's significantly cheaper than Duolingo. This may not seem right on the surface. After all, Duolingo offers a free, ad-supported plan. Ling offers a free trial but requires you to pay. Ling's monthly price is also a few dollars more expensive than Duolingo and does not offer a family plan.
So what is cheaper? Ling offers a lifetime subscription for $150. That's roughly the cost of a year of total monthly payments, or 2 years if you pay annually. This is a lot of money to commit upfront, but it's a bargain if you like what you see in the app.
Ling is good enough to replace Duolingo

Is Ling better than Duolingo? No one can answer this question because each person will have a different feeling about the application
What can be said is that, so far, Ling has been good enough. This application is easy to use. The entire experience feels very carefully crafted. You hear many different speakers. In a sea of cheap language learning programs, the app deserves praise.
If Duolingo works for you, great! Please use it consistently. But if you don't see the language you're looking for or think Duolingo is as good as it used to be, consider Ling.
