What's New in Trellis
1.4
October 26, 2026
Made for iPhone Duo: open it and Trellis spreads out with a sidebar, then folds back to the phone layout when you close it. Stand your iPhone on its side and Trellis now works in landscape, too. Habit details make better use of a large screen: the 26-week heatmap fills the width, and the stat tiles line up. Cleaner toolbar buttons.
