Features
Stepwise Tutoring
Guided 5–7 step flows walk you through pH, primary process, compensation, and diagnosis — just like an attending at the bedside.
Expert Mode
No hints. No steps. Just the numbers and a text field. Designed for residents who want to test raw interpretation speed.
Infinite Cases
Procedural generator creates realistic ABGs across all disorder types — simple, mixed, and triple — with physiologically valid numbers.
Instant Feedback
Real-time validation on every step. Wrong answers explain why, not just what. Delta-gap, Winter's formula, anion gap — all computed live.
Offline-Capable PWA
Installable web app works offline. No app store required — just open the link on your phone and add to home screen.
No Login, No Data
Zero accounts, zero tracking, zero analytics. Your practice sessions stay on your device. Privacy by default — not as an afterthought.
