eCalc: Sale Counter Calculator

eCalc is a fast, no-fuss calculator built for the shop sale counter — not a general-purpose calculator, a tool for the specific rhythm of ringing up sales.

Pack-size keys: type a unit count and tap a box size (12/px, 24/px, etc.) to get the total instantly — no manual multiplication for every case sale. Pack sizes
are fully customizable in Settings.

Running Total & Memory: a running Total accumulates automatically as you go, and a separate user-controlled Memory (M+/M−) stays visible on screen. Tap MRC once to recall it, twice to clear it.

Transaction tape: every calculation for the session is logged in order, right on screen — a running audit trail, not just a single throwaway answer.

Unit converter: tap UNIT to convert length, area, volume, weight, speed and temperature — including local land and gold units like ankanam, cent, guntha, acre and tola, plus quintal. Type in one field and the other updates instantly; press = to carry the result back into your calculation.

Share the tally: one tap on SHARE (on the last page of the box keys) sends the running Total and the full transaction tape to WhatsApp, SMS, or any app you
choose — hand the day's numbers to someone without retyping.

Undo a clear: if you hit AC by mistake, an undo appears right next to it — tap it to bring the tape and Total straight back.

Built for speed: large touch targets, Indian digit grouping (12,34,567), and a layout designed for one-handed, rapid entry during a busy counter rush. Works in both portrait and landscape.

Works fully offline: no account, no internet required. Pack sizes, memory, and totals are saved automatically and persist between sessions.
