A fast, no-fuss calculator for Android, built for the exact rhythm of a shop sale counter — not a general-purpose calculator repurposed for the till, a tool designed around how a real counter actually works. Pack-size keys, a running total, a shareable tape, and a unit converter that speaks ankanam, cent, guntha and tola.
Most calculator apps are built for arithmetic homework. eCalc is built for a busy counter, case sales, and a running tab.
15 customizable pack-size keys — type a unit count and tap a size to get the case total instantly. Swipe through the pages in either direction; they wrap around.
A running total accumulates automatically as you go. A separate memory (M+/M−) stays visible — tap MRC once to recall it, twice to clear it.
Every calculation for the session is logged in order, right on screen — pack conversions included, e.g. 9 + 36(3*12) = 45.
The UNIT convert key handles length, area, volume, weight, speed and temperature — including local land and gold units. Press = to carry the result back into your sum.
One tap on SHARE sends the running total and the full tape to WhatsApp, SMS, or any app — hand over the day's numbers without retyping.
Hit AC by mistake? An undo appears right beside it — one tap brings the tape and total straight back.
Totals display grouped the way Indian currency actually reads — 12,34,567 — not the international 1,234,567 style.
Large touch targets for one-handed entry in portrait, and a side-by-side display and keypad when you turn the phone sideways.
No account, no internet required. Pack sizes, memory, totals, tape and converter units are saved on-device and persist between sessions.
15 keys, five to a page — set your own sizes once, then it's one tap per case. The last page holds the settings gear and SHARE.
Tap UNIT convert and the pack keys become categories; tap CALC (or =) to go back. Type in one field and the other updates instantly.
