What's New in Iron Diary
1.2.0
September 6, 2026
Session notes Add a note to the whole workout, not just one exercise. "Short on time, cut the accessories" is the context that explains the numbers six months from now. It shows in the editor, on the history card, and in your backups. Estimated 1RM, point by point Tap any point on an exercise's 1RM trend to see the set behind it, step through sessions one at a time, and jump straight to that day in your log. Cleaner personal records A brand-new exercise no longer badges every set as a PR. Records now wait until there is real history behind the lift. On Deck Delete a planned workout with a swipe or from the row menu. The Diary's "next up" suggestion and On Deck now always agree on what comes next, and the On Deck card steps aside once today's session is under way.
