## Description

Never lose track of your math. Sumi keeps every line on a running tape you can edit, annotate, and total instantly — on iPhone, iPad, and your Mac menu bar.

  Sumi is a calculator that remembers.
  
  Instead of a single number that disappears the moment you hit equals, Sumi shows your whole calculation as a running tape — every line
  visible, editable, and adding up to a live total. It's the fast, frictionless way to work through anything from a quick estimate to a
  full list of expenses.
