Lemonade Stand

Lemonade Stand turns a phone or tablet into a simple, ultra-legible cash register designed for young entrepreneurs and outdoor drink pop-ups. Built with large high-contrast touch targets, bare whole-number currency, visual coin chips, and contactless tap-to-pay via NFC, it streamlines drink orders and teaches change counting without clutter.

High-Contrast Poster UI

Large 76px+ touch targets and dark ink outlines ensure direct-sunlight readability and easy tapping.

Visual Coin Chips

Illustrates currency notes and coins so cash tenders and change breakdowns are solved through visual recognition.

NFC Tap-to-Pay

Accepts contactless card and device taps right on the phone without needing external card readers.

Attributed Till Ledger

Tracks today's earnings, cup counts, and tips attributed strictly to the station's own completed sales.

Pin-Protected Settings

Keeps price toggles, stand names, and station home navigation tucked safely behind a long-press on the sign.

1. v1.1.1Live
   Sep 16, 2026 · 2:27 PM

   Money amounts now show the host currency mark so prices no longer look like cup counts. - Totals, tenders, change, tips, takings and the settings price use the company's currencyPrefix/currencySuffix (falling back to currencySymbol). Whole amounts stay without trailing .00. Cup quantities stay bare numbers. - Note chips show $5 rather than 5; sub-unit coins still use the cents glyph alone. - Short landscape phones can reach every CTA: the frame scrolls under 520px height, and Pay/Change keep an internal scroll so TAP CARD and GIVE IT BACK are not clipped.

2. v1.1.0
   Sep 16, 2026 · 1:21 PM

   Card payments now follow the platform pattern used by Vision Desktop, Mobile and Kiosk: the flow no longer draws its own tap-to-pay prompt. - Removed the dedicated Tap Card page. Tap now runs inline from the Pay screen and shows a neutral PROCESSING state while the reader and the host own the cardholder prompt. Eight host pages instead of nine. - An order's price and options are frozen when it is rung up, so changing settings mid-transaction can no longer alter what a customer is charged. - While a payment is on the wire, the store refuses order, settings and till mutations, and the screens reachable from the host page menu disable their controls to match. Previously a host-menu jump could clear the lock and start a second charge. - Every page that needs a live order re-checks that on mount, so jumping straight to Pay, Cash, Change or Paid from the host page menu returns to the stand instead of reopening a finished sale. - Tap-to-pay treats the host's settlement fields as corroboration when present and never refuses a payment merely because they are absent.
