About this app
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−) is always visible and one tap away to recall — no hunting through menus.
Transaction tape: every calculation for the session is logged in order, right on screen — a running audit trail, not just a single throwaway answer.
Share the tally: one tap on SHARE 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.
Free to use, supported by ads.
