A calculator that remembers your work. Voice, OCR, history, and archive - for anyone who runs the same numbers more than once.
A tape calculator that doesn't forget.
Every number you tap goes onto a tape you can scroll, edit, save, and come back to. No more wiping the screen by accident and losing the whole calculation. No more squinting at one line of digits, trying to remember what you were even working on.
DIGITCA is built around a simple idea: numbers deserve a paper trail.
The tape isn't just a log. It's the calculator itself. Tap any number to change it on the spot and watch the totals update live. Scroll back through every step. Autosave keeps your work safe between sessions.

Ratings & Reviews
Fixes & improvements
- Text and voice input for labeled items now works correctly — "Material 300 labor 200 shipping 150 + 21% Vat" writes each item as a separate tape row
- Labels from dictation are automatically capitalized
- Words after the percent sign (e.g. Vat) now appear as a row comment on the tape
- "Name this…" appears once for the whole tape, not after every result
