Recent gases from older versions now show the same verdict Interpret gives today. Very long pasted values no longer round onto a range edge. If you were already asked for a rating, you won't be asked again. At the largest text sizes, the Guide's step numbers stay inside their circles, iPad drill titles no longer get cut off, and the Review your misses banner grows with your text.

Values are interpreted exactly as you enter them, readings right on a compensation boundary are judged correctly, and an impossible entry now asks you to check it instead of guessing.

Interpret now checks the compensation. After naming the disorder, the app runs the expected-compensation formulas — Winter's formula and its respiratory and metabolic counterparts — shows the predicted range, marks your measured value on it, and names the concurrent disorder when the value falls outside. Full precision, sources cited. 2027 edition. New icon.

• Recent: every gas you interpret is kept on your device; tap one to bring it back
• Accuracy over time on the Drill tab, one point per day you practise
• A Settings tab with light and dark appearance, reference ranges and the disclaimer
• Light mode, a new look, and the whole app in sentence case
• The classifier is unchanged and re-verified against a 27-cell textbook oracle and a 10,000-case sweep
• Now on iPad: the values, the pH band and the reading laid out across the screen like a bench analyser, in every orientation
