The top eLearning mobile apps in 2026 are Duolingo, Coursera, Khan Academy, Google Classroom and Quizlet. They lead for different reasons: Duolingo for habit-building, Coursera for career courses, Khan Academy for free school-level learning, Google Classroom for teachers and Quizlet for self-study. This guide gives current numbers for each, what they do well and what you can borrow if you are building your own eLearning app.
Key Takeaways
- Duolingo reported 58.7 million daily active users and 12.7 million paid subscribers in Q2 2026, which shows how far habit design and a freemium model can scale.
- Coursera reported 205 million registered learners in Q1 2026 and merged with Udemy in 2026.
- Khan Academy, a nonprofit, reported 189.6 million registered users in the 2024-25 school year, including 2.0 million Khanmigo AI tutor users.
- AI tutors are now built into the leaders: Duolingo, Khan Academy, Google Classroom and Quizlet all offer them.
- The features worth copying are streaks and rewards, short lessons, progress tracking, AI help tied to the learner's own material, and a clear free-to-paid path.
Why are eLearning mobile apps growing?
Learners want short lessons they can finish on a phone, and schools and employers want results they can measure. Market estimates for mobile learning vary widely. Published forecasts put the 2030 market anywhere from about $96 billion to $388 billion, depending on whether a report counts only apps or all mobile-delivered learning (GII Research listing). Treat any single figure as a rough guide. The usage numbers from the apps themselves are easier to trust, and they are below.
How do the top 5 eLearning mobile apps compare?
| App | Best for | Latest user figure | How it makes money |
| Duolingo | Learning languages daily | 58.7M daily users, 140.6M monthly users (Q2 2026) | Subscriptions plus ads |
| Coursera | Career courses and credentials | 205M registered learners (Q1 2026) | Subscriptions, courses, enterprise |
| Khan Academy | Free school-level lessons | 189.6M registered users (2024-25) | Nonprofit, funded by donations |
| Google Classroom | Teachers running classes | Not published in the sources we checked | Part of Google Workspace for Education |
| Quizlet | Flashcards and self-study | Reported over 60M monthly users (unconfirmed) | Free tier plus Plus subscription |
The numbers are not directly comparable. Duolingo reports daily and monthly active users, Coursera and Khan Academy report registered users, and registered counts include people who may no longer use the app.
1. Duolingo: the benchmark for habit-building
Duolingo teaches languages through short, game-like lessons. In Q2 2026 it reported 58.7 million daily active users (up 23% year over year), 140.6 million monthly active users, 12.7 million paid subscribers and revenue of $298.5 million. Current-user retention hit a record 84% (Duolingo Q2 2026 shareholder letter, Pulse 2.0). Part of the growth came from a one-time Streak Revival campaign in June that about 15.4 million learners joined.
- What it does well: streaks, rewards and bite-sized lessons keep people coming back daily.
- What to copy: one clear daily habit, visible progress and a free tier good enough to build the habit before asking for payment.
- Watch out for: gamification only works when the lessons are good. Points alone do not teach.

2. Coursera: courses and credentials at scale
Coursera partners with universities and companies to offer courses, certificates and degrees. It reported 205 million cumulative registered learners at the end of Q1 2026 (Coursera Q1 2026 results). Its filings describe an all-stock merger with Udemy completed in 2026, and Q2 2026 revenue of $298.6 million, including $103.8 million related to the merger (Coursera 10-Q, June 30, 2026).
- What it does well: credible content partners, structured learning paths and credentials employers recognize.
- What to copy: offline downloads, course progress syncing across devices and clear certificates at the end.
- Watch out for: registered learners are a cumulative count, so they overstate how many people are active today.
3. Khan Academy: free learning with an AI tutor
Khan Academy is a nonprofit offering free lessons and practice. Its annual report for the 2024-25 school year lists 189.6 million registered users, 104.9 million yearly active learners and 2.0 million Khanmigo users, its AI tutor (Khan Academy annual report). Khanmigo is a good example of AI built into a learning flow: it guides learners with questions instead of handing over answers.
- What it does well: mastery-based practice, free access and teacher tools.
- What to copy: an AI helper that asks guiding questions, and clear progress per skill.
- Watch out for: a free model needs donors or another funding source. Plan your revenue early.
4. Google Classroom: the teacher's workspace
Google Classroom lets teachers create classes, share materials, set assignments and give feedback. In 2025 Gemini AI tools became available across all Google Workspace for Education editions (Google Workspace Updates, June 2025). In August 2026 Google announced that Gemini in Classroom would open to students of all ages, where admins allow it, starting August 10, 2026, with prompts tied to a specific class and assignment and the ability to create flashcards and practice quizzes from course materials (Google Workspace Updates, August 2026). Availability depends on each school's admin settings.
- What it does well: assignment flow, grading and integration with Google Drive and other Google tools.
- What to copy: teacher dashboards, announcements and AI that works on the teacher's own materials.
- Watch out for: school apps need admin controls and strong student privacy from day one.

Quizlet offers flashcards, study modes and games built from learners' own sets. One directory listing puts it at over 60 million monthly users, which we could not confirm from Quizlet itself. Its AI study assistant, Q-Chat, is described by reviewers as available through the paid Quizlet Plus plan, not the free tier (Tool Directory). Check Quizlet's own pricing page for current prices.
- What it does well: simple content creation and a free tier that gets students started.
- What to copy: let learners create their own content, and put AI features behind a clear paid plan.
- Watch out for: user-made content needs moderation and quality checks.

How do you build an eLearning mobile app?
- Define the learner and the outcome. One audience and one result, such as "pass a language test" or "finish a certificate".
- Choose the learning format. Short lessons, live classes, video, quizzes or a mix.
- Pick the revenue model early. It shapes your features and your free tier.
- Design the habit loop. Reminders, streaks, progress and rewards that fit your subject.
- Add AI where it helps. Personal practice, explanations and feedback, with limits on wrong answers.
- Build an MVP. Sign-up, one learning path, progress tracking and payments.
- Measure and improve. Track lesson completion, retention and what makes people quit.

What changed from the earlier version of this list?
An earlier version of this post, written in 2022, listed Google Classroom, Seesaw, Duolingo, Photomath and Quizlet. We kept Google Classroom, Duolingo and Quizlet, added Coursera and Khan Academy, and removed Seesaw and Photomath because we could not verify current 2026 usage data for them. The 2022 market figure ($250 billion in 2020) is no longer used.
