Why sololearn has many versions? Is that sololearn java for example better than sololean?

Question

Why sololearn has many versions for different languages?

What's the different between them?

Answer 1

Actually, Sololearn java is a small fragment/part of the Sololearn... It has no difference...

These are not versions, rather these are small parts of Sololearn made for people who only want to learn one language, or has less internet to download the whole app, or less memory in device to keep it...

Answer 2

I'm not sure why they still have the single language apps. Maybe to compete with other single language apps.

Answer 3

Use Sololearn. Each language used to have its own Sololearn (like Sololearn java). Later they unified everything into one Sololearn.
