Sololearn is a coding-only microlearning app: short lessons in Python, JavaScript, SQL, and more, a code playground that runs on your phone, a hearts system on the free tier, and a large learner community. For a first programming language on a phone, it is a sensible default.
MindShark covers programming as one topic among any you name. You get a Deep Dive with quizzes and explanations, a diagnostic, and adaptive difficulty — but no code editor. Sololearn lets you run code; MindShark tests whether you understand it.

Sololearn MAX (AI assistant, unlimited hearts) is annual-only with no trial.
Sololearn is the right choice if you are learning your first language and want to type code on the train. The playground and the community are real advantages, and the free tier is workable if you tolerate the hearts.
MindShark suits the learner who wants the concepts to stick — a diagnostic, quizzes that adapt, and misses that come back — and who is learning more than code. It will not run your Python. Many people pair the two: MindShark for the ideas, a playground for the practice.
Yes, with a hearts system, ads, and no AI features. PRO removes the limits; MAX adds the AI assistant.
$12.99/mo or $69.99/yr. MAX is $119.88/yr, annual only. MindShark Premium is $7.99/mo or $49.99/yr.
No. MindShark teaches through quiz-driven Bites and explanations; it has no code playground.
Mimo is more project-driven and gamified; Sololearn has the bigger community and a cheaper annual plan.
