Turn gradients on or off

1. Open More > Settings > Appearance and turn Gradients off (or on).
2. On (the default), the whole app uses two-colour (duotone) blends: each area goes diagonally from your theme colour at the top-left into a neighbouring colour at the bottom-right (Forest: green into teal; Blue: into indigo; Rose: into coral). That covers the background of every screen; Total balance and other feature panels; every card and list (Safe to spend, Next month, Upcoming payments, This month, accounts, transactions, budgets, goals, settings), which in light mode are near-white blending into a pale mint (the theme's partner colour) and float on a layered shadow (tight at the edge plus a wide soft one) instead of a border, and in dark mode are charcoal with a subtle teal tint, a faint light along the top edge and a deep shadow; the + button and main buttons (Save, Use amount, Set date); the selected choice in filters, segments and the bottom bar; avatars; pop-up sheets; and home-screen widgets (in every widget style).
3. Off draws all of these in one flat colour of your theme.
4. Card and account artwork, text boxes and charts stay as they are either way. The PC Manager follows the same switch (Settings > Preferences > Gradients there too): page background, panels, main buttons and the sidebar.
