Ollin, Poker Skill, River, Sharkling and Stack Poker are Duolingo-style poker learning apps, each pairing short lessons with a daily reason to come back. On Android, Ollin puts a coach on every hand you play and adds short lessons and a daily puzzle. We make Poker Skill: its lessons start at the rules and hand rankings, and a daily streak keeps the habit going. River places you with a quiz and has an AI coach for your questions.
Sharkling runs on Android and the web, with a free library of solved flops. Stack Poker builds its streaks around ranked duels, on iPhone only. If you would rather watch long video courses, PokerCoaching and Upswing Poker are built for that.

What makes a poker app Duolingo-style
A Duolingo-style app keeps each lesson short, ends it with a decision you make yourself, marks your answer on the spot and gives you a reason to open it again tomorrow. The decisions do the teaching: pulling a play out of memory to answer is what makes it stick, and the streak only brings you back for the next one. Poker Skill brings you back with the Daily Puzzle, which shows its difficulty before you answer, rated by how often players get that spot right on the first try. Order matters too, because a path that starts with hand rankings and position teaches you to read a spot before it asks you to count a draw’s chances with the rule of 2 and 4.
Run this test for a week
Short daily lessons or a video course
Short lessons suit a learner who has ten minutes a day and wants to spend that time on decisions. Poker Skill is built for that learner: in its lessons you make each move yourself. A video course goes deeper on one topic at a time, and you spend more of it watching than deciding, so it suits a player who knows the basics and wants a coach’s full reasoning. PokerCoaching’s Premium membership costs $147 a month or $999 a year and includes 600+ video classes, 70+ structured courses and 1,500+ interactive hand quizzes. The Upswing Lab training library costs $99 a month.
How we compared
The five were compared on their lessons, the daily habit each one builds, what the free version gives you and the devices each runs on. Facts about Poker Skill come from its store listings, this site and the app itself. Facts about the other four come from their own store listings, websites and plan pages. Trainers that drill preflop ranges or solver spots with XP added on top are left out: they practice charts more than they teach a path from the rules up. Learning apps that run prize contests or tie into a real-money poker site are left out too. Anything that could not be confirmed at its source is left off.
