Worked examples now show every step: simplifying in two moves, and systems solved by elimination. Lessons write formulas in math, not words. Check, Next and Why? answer a tap anywhere on the button, your answer stays in view after a miss, and the scratchpad keeps your working when you close it. A climb that iOS closes in the background is kept, and the screen stays awake while you work on a problem. Easier reading at every hour on the mountain, with true minus signs, raised exponents, and a joined square-root sign. The home screen names your next camp and what is left to reach it.

Settings has a new Rate Ascent link. After a camp arrival, a passed Route Test, or a week-long streak, Ascent may also ask once for a rating, never in the middle of a problem. Copied Weather Window results and shared summit certificates now include a link to Ascent, so friends can join the climb. Clearer wording on the Full Expedition sheet.

The scratchpad now types on the algebra keys, with a space bar and a new line, so you can lay out your working a step per line without a phone keyboard in the way. Fixed: choosing Type in the scratchpad could leave you with no keyboard and no clear way back out. Fixed: on a graph question, the message after a wrong answer shrank the coordinate plane. It now stays full size, so the points are as easy to move as they were. The radio to Base Camp introduces itself the first time you get an answer wrong, because asking for a hint is part of climbing. Added support and website links in Settings.
