What's New in WeighCast
1.0.1(18)
August 23, 2026
- Your forecast no longer over-promises on distant goals. It used to assume your current rate of change would hold all the way; it now allows for progress slowing as your weight changes, so far-off dates may move later — that later date is the more truthful one. Goals close to your trend barely change. - Added home-screen widgets: your arrival range, trend weight and next milestone, in a small and a medium size. - Added Whats New - After an update, WeighCast shows a short summary of what changed — once, with the history kept under Settings › About › What's new. - The Trend and Forecast charts now remember your chosen time range. - Clearer wording in a few places, including the PDF export of your data. - Squashed some bugs.
