Edit any past number — totals update live. Carry one row's result into the next. Annotate rows with comments and color highlights. $6.99 unlock, no subscription. Calcoo is a calculator that keeps every step on screen — and lets you edit any of them. Type a row, hit return, type the next. Change a number from earlier and everything below recalculates. Tap the result of any row to carry it into the next. Plan a trip across five rows: flights (845 + 845), hotel (180 + 180 + 180), meals (48 + 62 + 75 + 31), transit (35 + 22 + 18), and your share. Carry the hotel total into the last row and divide by four. The split stays linked — if the rate drops, your share updates. Each calculation lives on its own sheet. Name it, pin the ones you keep coming back to, and share a snapshot with anyone. No sign-up, no account. Calcoo Pro adds comments and row highlights so you can annotate any line of math, plus editable share links, accent colors, and unlimited sheets.
