When a spreadsheet or an automated system hands you a total, checking it inside the same system isn’t really a check. DeskCalc lets you re-add the figures yourself — on a visible tape, fully offline, with every line in plain sight — so the verification is independent of whatever produced the number.
Add up a column in any PDF — a statement, an invoice, a scanned report — without Acrobat Pro and without a plug-in. Copy the figures or capture them with Click & Calc, and keep a labelled tape you can print or save as a PDF.

Tax season still runs on tapes: receipts added up for Schedule C, brokerage lines checked against the 1099-B, a client's own totals ticked and tied. DeskCalc puts that 10-key tape on your Windows PC — every line labelled, correctable, and saved as a PDF for the workpapers instead of stapled to them.

Add up a week of working hours on a normal calculator and you get the wrong answer: 7.45 + 8.30 is not 15.75 hours. DeskCalc has a time calculator built in. Switch it on, type the hours and minutes, and the tape adds them the way a clock does — every line visible, every line correctable.
