Chessis MOD APK (Pro Unlocked)

Chessis is a powerful chess analysis app that helps players of all levels improve their game by analyzing moves, detecting blunders, providing detailed game reports, and offering deep engine-powered insights — all with a free version and an optional Pro upgrade.

A Smarter Way to Understand and Improve Your Chess

Every chess player — whether a beginner learning the basics or an experienced competitor chasing a higher rating — shares one common goal: getting better. The fastest way to improve is to understand your mistakes, learn from them, and apply those lessons in your next game. Chessis makes that process effortless, powerful, and deeply insightful.

Chessis is a feature-rich chess analysis app built to help you dissect your games, identify where things went wrong, and show you exactly why a move was a mistake — not just that it was one. With the industry-leading Stockfish engine under the hood and an intuitive interface packed with tools, Chessis gives you everything you need to study smarter and play stronger.

Fresh Updates That Make Chessis Even More Powerful

The Chessis team continuously works to improve the app and deliver new features that enhance the analysis experience. The latest round of updates brings some exciting additions that expand what the app can do.

The new Chess Image Scanner lets you point your camera at any 2D chessboard image and instantly load the position for analysis — no manual setup required. Engine vs Engine mode lets you sit back and watch two powerful engines battle each other, giving you a fascinating look at high-level chess in action. Smart Analysis delivers deeper positional insights when you enable it in the analysis settings, while the integration of Stockfish 18 — the latest and strongest version of the world-renowned engine — ensures you always get the most accurate evaluations available.

The update also adds App Shortcuts so you can long-press the app icon for instant access to key features, direct Lichess game browsing so you can pull up and analyze your games without leaving the app, Annotated PGN Export so you can download your analyzed games with notes included, and support for 13 languages to make the app accessible to players around the world.

A Complete Toolkit for Chess Analysis

Chessis packs an impressive collection of analysis tools into a single app, giving you a one-stop platform for every aspect of chess study.

You can load your games directly from Chess.com or Lichess and let the engine tear them apart move by move. The app generates detailed game reports that highlight your blunders, mistakes, missed wins, and best moves, so you can see at a glance where the game slipped away from you. It also calculates your accuracy percentage and average centipawn loss, giving you concrete metrics to track your progress over time.

When you want to explore specific positions, the Board Editor lets you set up any arrangement of pieces and run instant analysis on it. You can open PGN files through the built-in PGN Viewer, search the games database using FEN codes, and browse a comprehensive list of chess openings to deepen your theoretical knowledge.

The app also lets you play chess against the computer at a difficulty level that matches your skill, with the option to play on the clock or set a custom engine think time. You can add multiple engine lines, play through those lines interactively, draw arrows on the board to visualize ideas, show threats, and even enable Chess960 for a fresh and challenging variation of the game. Advanced users can push further by adding OEX engines and fine-tuning engine settings like hash value and thread count.

Upgrade to Pro and Unlock the Full Experience

Chessis keeps the majority of its features free so that every player can access quality analysis without spending a cent. For those who want to take their study sessions even further, the Pro version unlocks a powerful set of premium tools.

Pro members gain access to deep analysis mode, which delivers significantly more accurate and consistent results compared to standard quick analysis. You can add unlimited engine lines, adjust game report depth and time to suit your study style, and enable NNUE for enhanced neural network evaluations. Pro also gives you real-time feedback while you play, including move strength indicators and mistake alerts that catch errors as they happen rather than after the fact. On top of all that, Pro removes all ads and lets you analyze unlimited games forever.

Start Analyzing and Start Winning

Chess improvement does not happen by accident — it happens through deliberate study, honest self-assessment, and a willingness to confront your weaknesses. Chessis gives you all the tools you need to do exactly that. It shows you where you went wrong, explains why the move failed, and points you toward better alternatives so you can build better habits with every game you play.
