About TowCal - Hitch Calendar
TowCal is built for working mariners who live by the hitch. If you run a rotation — 20 and 20, 28 and 14, or any schedule that keeps you away from home — TowCal keeps your calendar, your pay, and your credentials in one place. ROTATION CALENDAR See your entire hitch at a glance. Track crew-change days, days on and days off, and know exactly where you stand in your rotation. PAYDAY TRACKING Estimate your pay with day-rate and per-diem calculations built for how inland towing actually works. Know what's coming before it hits the account. CREDENTIAL REMINDERS Keep your MMC, TWIC, and other endorsements from lapsing. Track expiration dates so you're never caught short before a crew change. BUILT BY A MARINER TowCal was created by a working towboat captain who got tired of tracking hitches on paper and phone notes. Every feature is designed around life on the boat. SUBSCRIPTION TowCal is a subscription — pick the plan that fits your schedule: Monthly, or Annual with a discounted introductory first year. Each plan renews automatically until cancelled. Cancel anytime through your Apple account settings. Terms of Use: https://jackstaffdigital.com/terms.html Privacy Policy: https://jackstaffdigital.com/privacy.html Questions or feedback?

What’s new
Version 1.4 · Updated July 31, 2026
TowCal now runs natively on iPad — a full tablet layout with a wider calendar, roomier calculators, and side-by-side barge views. - NEW: Discharge Calculator with a visual barge diagram — pick 30k or 10k, set the shape, roll each tank gauge to your reading, and get total pump-off time (with stripping) and the clock time you'll be empty. - NEW: Transfer Times — your own ledger of dock load/discharge times. Log a transfer and TowCal reminds you how long that dock took last time you were there. - NEW: Setting up a new iPhone or iPad? TowCal can find your data from your other device (via iCloud) and set the new one up in one tap. - Major holidays now appear above the calendar — green when the rotation says you're home, red when you're working or crew-changing. - Money: a large batch of accuracy fixes across paychecks, bills, and debt tracking. - Backups now include your calculator settings and transfer-time ledger. - iPhone stays in portrait; iPad rotates freely.
