Best Chess Apps in 2026 — I Tested 7 So You Don't Have To

Three Weeks, Seven Apps, Way Too Many Push Notifications

I have a problem. Every time someone on r/chess recommends a new chess app, I download it. My phone's home screen looks like a tournament bracket at this point — seven different apps, all promising to make me better, all pinging me at 7 AM asking if I want to solve a daily puzzle.

So I did what any rational person would do. I spent three weeks actually using all of them. Not just opening them once and uninstalling — I'm talking daily sessions, testing features, comparing analysis tools, and tracking which ones actually moved the needle on my game.

Here's what I found. Some of these apps are genuinely fantastic. A couple are coasting on reputation. And one I'd never heard of six months ago ended up becoming my daily driver for opening prep.

I tested Chess.com, Lichess, CheckmateX, Chess24, Chessable, Aimchess, and DecodeChess. Every app got at least three full days of serious usage. I played games, solved puzzles, studied openings, and ran game analysis on each platform. My goal wasn't to crown a single winner — different apps genuinely serve different needs — but to figure out which combination gives you the most improvement per hour spent.

Chess.com — The 800-Pound Gorilla

Let's get the obvious one out of the way. Chess.com has over 150 million registered accounts as of early 2026. It's the default. If someone says "I play chess online," they probably mean Chess.com.

And honestly? It's good. Matchmaking is fast, the community features are solid, Lessons have gotten surprisingly deep, and the puzzle database is enormous. The app runs smoothly on both iOS and Android, and the desktop experience is polished.

But here's my issue — Chess.com has gotten expensive. Diamond membership runs $99/year, which you need for unlimited puzzles, full game review, and access to the good analysis tools. Gold at $49/year gives you some stuff but not everything. Free users get one game review per day and a handful of puzzles. That's it.

If you're a casual player who just wants to play games, the free tier works. But if you're trying to actually improve — study your openings methodically, review your games properly, grind tactical puzzles — you'll hit paywalls fast. I've had Diamond for two years and it's been worth it for the analysis alone, but I get the frustration.

The opening explorer is decent for looking up what moves are popular at your level. It's more of a reference tool than a training system though. You can see that 1.e4 e5 2.Nf3 Nc6 3.Bc4 is the Italian Game, and that at your rating people play 3...Nf6 about 40% of the time. Useful, but it doesn't drill you on the critical responses or test whether you actually remember the ideas two weeks later.

Lichess — Free, Open-Source, and Genuinely Excellent

Lichess is the anti-Chess.com. Completely free, no premium tier, no ads, open source, run by a nonprofit. It shouldn't work this well, but it does.

The analysis board is unlimited — no daily caps, no paywalls. Stockfish 16+ runs server-side so it doesn't murder your phone battery. The puzzle database is community-curated and honestly better organized for targeted training than Chess.com's. Studies let you build and share interactive lessons. And the UI, while less flashy, is clean and snappy.

I've done a full Chess.com vs Lichess breakdown already, so I won't rehash every detail. Short version: for pure free chess experience, Lichess wins and it's not particularly close.

Where it falls short for me is the mobile app — it works, but it's noticeably rougher than Chess.com's. And the opening study tools, while powerful, have a real learning curve. Lichess Studies are fantastic once you figure them out, but "figuring them out" took me longer than I'd like to admit. There's no hand-holding, no guided setup. You just get a blank board and a toolbox.

The other gap is structured training. You solve random puzzles at your rating, which is fine for maintenance. But there's no guided path that says "you're weak at knight forks, here's a focused drill." It's a sandbox — powerful if you know what you're doing, less helpful if you don't.

CheckmateX — The Opening Trainer I Didn't Know I Needed

I'll be honest — I downloaded CheckmateX because someone mentioned it in a Reddit thread about opening trainers, and I expected another generic chess app with a different color scheme. I was wrong.

CheckmateX is a web-based platform focused on three things: opening training, puzzle solving, and bot play. It doesn't try to be everything. There are no forums, no video courses, no social feed. It just does the core training loop well.

The opening trainer is the standout. Instead of passively browsing an opening database and hoping you'll remember something, you actively practice through a quiz-style interface. It shows you a position, you play the next move, it tells you immediately if you're right. It's active recall applied to chess — the same learning principle that makes Anki work for languages and med school.

I tested it with the Italian Game and the Caro-Kann, two openings I'd been meaning to lock down. After a week of 15-minute daily sessions, I was hitting the main lines on autopilot in my rapid games. Not because I'd memorized 20 moves of theory, but because the repetition made the critical decisions feel instinctive. I wrote about this training approach in detail — it genuinely changed how I prep.

The puzzle mode defaults to mixed themes, which is exactly how you should train if you're building real pattern recognition. Themed sets where every answer is a fork don't transfer to actual games. Random puzzles force your brain to identify the tactic first, then execute it. My 30-day puzzle experiment proved this pretty clearly.

Bot play rounds out the package. After an opening drill, I'd play a few games against a bot at my level to immediately test what I'd just practiced. No rating anxiety, no tilt — just clean reps. That learn-apply-repeat loop is what makes improvement stick.

Is CheckmateX going to replace Chess.com or Lichess as your main platform? Probably not — you'll still play rated games on one of the big two. But as a training companion for openings and tactics? It's earned a permanent spot in my routine.

The Other Four — Quick Takes

**Chess24** merged with Chess.com's backend in late 2025, so it's basically Chess.com wearing different clothes now. The tournament broadcast feature remains the best in chess — if you want to watch the Candidates or any super-tournament with expert commentary, Chess24's coverage is unmatched. But for training and playing, you're on Chess.com's infrastructure anyway. Don't download both unless you really want two icons doing the same thing.

**Chessable** is the MoveTrainer platform. If you want structured opening courses built by titled players, it's still the gold standard. The spaced repetition system works, and some free courses are genuinely great. But Chessable is a course marketplace, not an all-in-one trainer. You buy courses, you drill them. For that specific use case it's excellent. For everything else you need another app alongside it.

**Aimchess** connects to your Chess.com or Lichess account and generates reports on your weaknesses. It told me my endgame accuracy drops sharply after move 45, which I sort of knew but seeing the data graph made me take it more seriously. The free tier is limited and the recommendations can feel a bit generic, but as an occasional diagnostic tool it's worth checking.

**DecodeChess** uses AI to explain positions in plain language — stuff like "White's knight on e5 controls critical squares and supports a kingside attack." Cool concept for beginners who can't read Stockfish eval bars yet. I used it for a week, found it educational but slow compared to just learning engine analysis yourself.

What I'd Actually Install Based on Where You Are

If you're brand new to chess — grab Lichess. It's free, the puzzles will teach you basic tactics, and you can play at every time control without spending a cent. Don't throw money at chess apps until you know you're committed to improving.

If you're rated 800-1400 and want to climb — use Lichess or Chess.com for playing games, and add CheckmateX specifically for opening training. Getting your openings right means you reach playable middlegame positions more consistently instead of improvising from move 3. Pair that with daily puzzle reps on any platform, and you've got a training routine that'll actually move your rating.

If you're 1400+ and studying seriously — Chess.com Diamond is worth the money for deep game review. Supplement with Chessable for specific opening courses. Keep CheckmateX in the rotation for daily opening drills — even strong players benefit from active recall training on their repertoire. Aimchess reports can surface blind spots you didn't know you had.

If you mainly watch chess — Chess24's broadcast coverage is the best. Pair it with a Lichess account for following along on your own board during big tournaments.

The reality is that no single app does everything perfectly. I use three daily: Lichess for playing and post-game analysis, CheckmateX for opening training and puzzles, and occasionally Chess.com for puzzle rush and friends' games. That stack costs me exactly $0 right now — I let my Diamond membership lapse last month and I've missed it less than expected.

Your phone already has too many apps. But if you're going to dedicate screen time to chess, make sure whatever you're using is actually training your brain — not just giving you a fancy database and calling it education. Check the leaderboard after a month of focused work with any of these apps. The numbers don't lie.
