Stund is a calculator whose numbers are hours, minutes and seconds. Type a column of times and get one exact total. Type a number, then its unit: 7 h 30 m. Add the next one. Every line stays on a tape, like the paper roll of an adding machine, so you can see what you typed and fix a line without starting over. • Add and subtract hours, minutes and seconds • Multiply or divide the total by a number: five days, three people • Tap any line on the tape to change it, swipe to remove it • Find the time between two clock times, also across midnight, and add it to the tape • Totals go past 24 hours (127:05) and below zero (−1:30) • Copy the total with a tap • Exact arithmetic: no rounding drift, however long the tape • Works offline. No account, no ads Made for the sums people do again and again: checking a timesheet before payroll, totalling a pilot's or driver's logbook, adding up clips for a video or audio edit, turning a week of sessions into billable hours. Type 90 m and Stund reads an hour and a half. Type 1.5 h and it reads the same. The unit keys say what each number is, so there is no mode to set and nothing to misread. STUND PRO A one-time purchase, not a subscription. It adds: • Decimal hours for payroll (7:30 = 7.50 h) and the pay at your hourly rate • Saved tapes: keep one for each week, job or logbook • Share a whole tape as text • Export a tape as a CSV file for a spreadsheet • Accent colors Stund reads every key and total aloud with VoiceOver, follows your text size, and comes in light and dark.
