Version 2.1 adds Checkout Guard, a pre-register readiness score that reviews budget risk, missing prices, category concentration, and saved price-history signals. The Budget tab now gives shoppers clearer next actions before checkout, with refreshed screenshots and updated support/privacy pages.

Spillproof 2.0 — a pro upgrade for group grocery runs, still 100% offline. • Cart Split: divide a priced list across people — evenly, by item, or by share — with exact-cent accuracy. • Settle-up: a minimal "who pays whom" from net balances, ready to share. • People roster with share weights and per-item assignment. • Price Book: record prices and get a "best price / good / typical / above usual" verdict per item, with a history chart. • Per-store aisle order: drag your categories per store, and the list re-sorts to match. No account, no network — your lists and prices stay on your device.

Version 1.3 Staples Library Save the grocery items you buy every week — milk, eggs, bread, olive oil — in a personal Staples Library. Tap the star button on the List tab to open it. Tap any staple to add it to your current list instantly, or tap "Add all" to push every staple onto the list in one shot (items already on your unchecked list are skipped automatically so you don't get duplicates). Each staple stores the same fields as a regular item: name, category, note, price estimate, and quantity. Staples are saved to your device alongside your list — no cloud, no account. Share your checkout brief The Budget tab's Checkout Brief now has a share button next to Copy. Tap it to send your cart summary to Messages, Notes, Mail, or anywhere else on iOS. Export trip history as CSV The Trip History screen now has a share button in the top bar. Tap it to export your full shopping history as a CSV file — date, time, store name, item count, and estimated spend per trip — ready to open in Numbers, Excel, or any spreadsheet app.

Version 1.2 Three new tools for smarter in-store shopping: Unit Price Comparator (Compare tab) Enter the price and size of two to four packages and Spillproof instantly tells you which is cheapest per ounce, gram, fluid ounce, liter, or count. Works across brands, sizes, and stores — offline, no math required. Trip History Every time you clear your checked items, Spillproof quietly logs the trip: date, item count, and estimated spend. See your last 30-day total and lifetime average in Budget → Trip History. Tap any trip to label the store. Store bug fix Corrected the "Clear checked" action to properly return and record removed items before deleting them.
