Clocktape: Hours Calculator

Clocktape is an hours and minutes calculator that works like a paper tape. Type one time per line, such as 8:30 or 9:00 → 17:30, and the total updates as you go. Change any line and everything below follows. ━━━ Time that adds up the way you expect ━━━ • Add and subtract hours and minutes: 8:30 + 7:45 = 16:15 • From → to: 9:10a → 5:40p is 8:30. A night shift like 10:00p → 6:15a crosses midnight correctly • Take off a break in the same line: 22:00 → 6:15 − 0:30 = 7:45 • Type minutes only: 100 becomes 1:40, 90 becomes 1:30 • Multiply and divide: 8:30 × 5 = 42:30, and 44:15 ÷ 8:00 gives a plain number (5.53) • Totals stay in hours: 1,284:35 shows as 1,284:35, not as days. Days are an option if you want them • Minutes always show two digits, and seconds (h:mm:ss) are an option ━━━ A tape you can fix ━━━ • Every line keeps its own result, with a name like Mon, Tue or NRT → HNL • Fix one line and the tape total changes at once • Tap a result to use it in another line, for example "Week − 40:00" for overtime • Swipe to delete, long-press to reorder, undo right after ━━━ The total, three ways ━━━ • 44:15 · 44.25 h · 2,655 min, shown together at the bottom • Decimal hours with 1, 2 or 3 places, handy for timesheets and payroll checks ━━━ Keys made for time ━━━ • A dedicated colon key, a from → to key, am and pm keys • Quick +0:15 and +1:00 keys, and a backspace that deletes one character at a time ━━━ For anyone who adds up hours ━━━ • Weekly work hours and time cards • Flight time for pilots and students • Study time, practice time and project time ━━━ No ads. Your data stays on your phone ━━━ • No ads, no account, no tracking • Calculations work offline • Copy a tape as plain text or share it to any app • Backup to an encrypted file is free • Light and dark themes and three text sizes ━━━ Free and Pro ━━━ Free: every calculation, copy and share as text, backup to a file, 1 group with up to 3 tapes.
