ShopTools v7.00

Quick List — a flat list for occasional buys: DIY tools, electronics, gadgets. Just a name and a number, no categories or stock tracking. Tap + to add one and start typing right away; double-tap a name to rename it, − / + for quantity, × to delete.
Inventory — Groceries (always here, pinned — can be renamed but not deleted) plus any other named lists you add (e.g. "Clothes", "Tools"), each tracked by category: current/recommended levels, low-stock coloring, tap a category's ⠿ to reorder whole sections, an item's ⠿ to reorder within its section. Tap + New inventory to add one, ✎ to rename, × to delete (Groceries excepted).
Stores — loyalty cards and opening hours in one place. A store doesn't need a card to get an entry — save just its hours if that's all you want.
Links — URLs you come back to, grouped into categories the same way Inventory is, with the same collapse and reorder.
Budget — set your recurring income and expenses (pick a frequency, it converts to a monthly figure) to see what's left over each month, then log spending as it happens to watch that "extra" count down in real time. Resets fresh on the 1st.
