Hello friends, today I want to introduce a learning app named as Sololearn where we can learn and run programming easily. They provide us java, c, c+ , HTML, CSS, Bootstrap, Ruby, Javascript etc. Here we can learn these things easily and run the codes in our android phone. Running programs in android, this feature is so good. Every programmer should like this app. And another best feature of this app is, here we can able challenge one another and earn some points and increase our level. These levels are bronze, silver, gold, platinum. So this is a best app for programmers. used this app for 2 months. And I am in a gold level.
