What's New in Compound259
1.2.0
August 11, 2026
The app has been redesigned. Typing now happens on a keypad built into the calculator. Tap any assumption to edit it, then use Prev and Next to move through all four without closing the pad. The growth chart has a time axis that adjusts to your horizon, from months on a short run to decades on a long one, and it moves between shapes as you type rather than jumping. Saved records, the share card, and the sheets for saving, renaming and deleting have all been rebuilt to match.
