## What is Read19?

Read19 brings cloud-powered KataGo analysis to iPhone, iPad, and Mac.

Play directly against AI and watch win rate and score lead update move by move. Import SGF records to explore candidate moves, principal variations, ownership, and whole-game trends. Read19 flags inaccuracies, mistakes, and blunders by win-rate and point loss, so you can focus on the moves that changed the game.

Your games and reviews stay on device. Sign in to sync privately with iCloud across devices and export standard SGF files. Read19 prefers secure WSS and falls back to HTTPS on restricted networks. Advanced users can connect to a compatible backend with custom HTTPS/WSS endpoints and an optional Bearer token.

Free includes 100,000 visits each calendar month with the Fast model. Plus unlocks the stronger Balanced model, more concurrency, and 2,000,000 monthly visits.

## Version history (last 5 releases)

### 1.7 — 2026-09-26

Rank estimates now stay in sync with the current game, with more reliable cancellation and reuse of saved analysis.
Improved responsiveness while saving analysis, along with more reliable game syncing, sign-in, purchases, and sharing.

### 1.6 — 2026-09-24

Landscape and wide screens now use a two-column workspace: a larger board, a collapsible inspector, and game state pinned with the primary actions on the side.
The live room becomes a left/right two-column layout on wide screens, and the animations respect Reduce Motion.

### 1.5 — 2026-09-23

Added an experimental, single-game rank estimate based on Human SL, with clearer results and explanations.
Improved retries and error messages for rank estimation, and refined layouts across screen sizes.

### 1.4 — 2026-09-14

Improved landscape layout with a larger board and controls on the right.
Improved rotation and layouts at different window sizes. Fixed an issue that could prevent smaller boards from rendering.

### 1.3 — 2026-09-12

Fixed an issue where background analysis prevented you from playing during your turn. You can now place a stone or pass immediately.
Improved loading and automatic retries for subscriptions and visits packs, with clearer messages when products cannot be loaded.
