$1.99 · Designed for iPad. Not verified for macOS.
Change any line and every total below it recalculates. The adding-machine tape, made editable.
Tenkey Tape is a 10-key adding machine that keeps every calculation on an editable paper tape. Add up a column of figures, then change any line — every total below it recalculates instantly.
THE TAPE
• Every entry stays on screen with its operator, its running total and your own comment
• Tap any line to correct a figure, switch + to −, or label what it was for
• Insert a figure you missed into the middle of a tape; nothing gets retyped
• Headings break a long tape into sections you can read back a month later
BUILT FOR BOOKKEEPING
• Exact decimal arithmetic — no floating-point cent errors
• Two tax rates, with +Tax to add tax and −Tax to extract the net from a gross amount
• Subtotals that keep going and totals that start a fresh calculation
• Memory keys, percentages and a Use Result key to carry a total forward
• Decimal places, rounding (5/4, banker's, up, down) and round-each-step to match a printed tape
• Thousands separator, Indian numbering and line numbers
KEEP IT AND SEND IT
• Save tapes by name, and duplicate one as a template for next month
• iCloud sync across iPhone, iPad and Mac
• Share as text, export PDF or CSV, or print the tape
• Full keypad on iPad, and a hardware numeric keypad works on iPad and Mac
No ads. No subscription. No account. Your tapes stay on your devices.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Tenkey Tape now speaks Japanese.
• Full Japanese interface, using the terms a bookkeeper expects — 端数処理 for rounding, 税込 and 税抜 on the tax keys
• On devices set to Japan, the second tax key starts at the 8% reduced consumption tax rate and amounts are shown in whole yen
Nothing changes if you are not in Japan, and any rate or decimal setting you have already chosen is kept.
