10 in 24
Part 135 Duty Day Planner
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Plan Part 135 duty and rest against § 135.267 and your company's limits — with saved plans, iCloud sync, PDF reports, and crew-to-crew Cockpit Sync.
10 in 24 helps Part 135 pilots plan duty and rest with confidence.
Enter your duty periods and flight legs, and 10 in 24 checks them against 14 CFR § 135.267 and your company's duty-time limits. Each duty period is marked compliant, caution, or exceeded — with the specific rule that applies — and the app calculates the extended rest you're owed after an exceedance, so you can see where you stand before you fly.
WHAT YOU CAN DO
• Build a day of flying — add duty periods and legs using Zulu times.
• See compliance at a glance — clear, color-coded status for every duty period.
• Track rolling flight time — the app watches flight time across the day and flags when a limit is approaching or crossed.
• Know your required rest — the mandated rest after any exceedance, including extended-rest tiers you can configure.
• Set company limits — override the default thresholds to match your operator's approved numbers.
SAVED PLANS & SYNC
• Keep multiple named plans and switch between them instantly.
• Sync your plans across your own iPhone and iPad through iCloud.
• Dated default plan names, or rename them your own way.
SHARE & EXPORT
• Export a full plan report as text or PDF from the share sheet — both duty periods, totals, and all rest and extended-rest results.
• Hand a clean, printable summary to a scheduler or keep it for your records.
COCKPIT SYNC
• Pair with another crew member over a local connection and share a plan device-to-device — no account, no internet required.
BUILT FOR THE FLIGHT DECK
• Clear Zulu time display throughout.
• Tap-to-enlarge explanations for quick reading in the cockpit.
• Optimized for large iPhones and iPad, with a side-by-side duty graphic and iPhone Duo dual-screen support.
10 in 24 is a planning aid. It is not a substitute for your operator's or the FAA's official rest and duty records. Always verify against your company's approved procedures and the current regulations.

2.4.6 Oct 24
Your duty days — now saved and synced.
SAVED PLANS
Keep a library of duty days instead of one calculation at a time. Tap the Saved Plans button at the top of the planner to create, open, rename, duplicate, or delete plans. New plans are named by date, and you can rename them anything you like. Starting a new plan no longer clears your old one — it stays saved in your library.
iCLOUD SYNC
Your plans now sync automatically across your own iPhone, iPad, and Mac signed in to the same Apple ID. Build a trip on one device and it's there on the others. No accounts, no servers — it stays in your iCloud.
SAVE OR PRINT A REPORT
Export any plan as a clean, printable PDF or as plain text from the ••• menu — then share it, print it, or file it for your records. No more screenshots.
Thanks for the feedback that shaped this release. Keep it coming through Support in the app.
2.4.5 Oct 6
• Moving Duty 2 into Duty 1 now brings everything with it. The duty on and off times, adjusted or derived, and every block out and in move across exactly as they were. Previously the arriving legs could inherit the show and release times from the duty they replaced — times chosen for a different day's flying — or quietly revert to the defaults. Thanks to the pilot who reported this with enough detail to reproduce it exactly.
• Update notices behave. A notice about a required update no longer appears as a dismissible card to pilots who are already on the version it asks for, and a notice that has been withdrawn now clears properly instead of lingering.
Fly safe.
2.4.4 Sep 23
v2.4.3 — Rearrange your legs by dragging.
ARRANGE LEGS
• Open Arrange Legs from a duty period to see your whole plan in one list — Show, every leg, Release, the Rest, and the second duty period.
• Drag a leg's handle up or down to set the order it's flown; the other legs slide aside to make room.
• Drag a leg across the boundary to move it to the other duty period — it lands exactly where you drop it.
• Near the top or bottom edge, the list auto-scrolls, so you can place a leg anywhere — even off-screen.
ALSO
• Support & Feedback moved to its own menu — and you can now attach screenshots to a report, so we can see exactly what you're seeing.
• Fixed a case where moving legs between duty periods could strand a custom Show or Release time a day out, stretching a duty by a phantom ~24 hours. A show or release time that no longer fits your legs now reverts to the automatic one.
RECENTLY
• 2.4.2 — Total flight time per duty period, and a simpler, dateless plan.
• 2.4 — Reorder your legs, and drag-to-edit to the exact minute.
2.4.3 Jul 22
v2.4.2 — Flight time per duty, and a simpler plan.
TOTAL FLIGHT TIME, PER DUTY
• Each duty period now shows its total flight time at a glance — in the duty header and on the Duty Visualization — so you can see the day's block time without adding it up leg by leg.
• Tap the ⓘ for what it means: it's a reference total, not a limit. The rolling 10-in-24 look-back is still the number that governs you.
TIMES ONLY — NO DATES TO MANAGE
• 10 in 24 now works purely from the times you enter and the order you place your legs. Your two duty periods always stay in sequence — Duty 2 simply follows Duty 1 — so a leg added out of order can't make the periods overlap or throw off the timeline. Just enter times; the app handles the rest.
• Drag-to-edit polish: the fine-tune pill from your last leg now clears the moment you grab another, so it never lingers on the wrong leg.
IN-APP MESSAGES
• The app can now show the occasional notice when you open it — app updates, regulatory reminders, and time-critical information.
• Each notice appears once and is easy to dismiss. To re-read one, open Messages from the menu — it keeps the notices you've received until they expire.
• Prefer not to see them? Turn in-app messages off in Settings. Critical safety notices always show.
RECENTLY
• 2.4 — Reorder your legs, and drag-to-edit to the exact minute.
• 2.3 — Drag to edit block-out/block-in and a duty's Show/Release on the Duty Visualization. Plus 10 in 24 on Apple Silicon Mac.
2.4.2 Jul 12
v2.4.1 — Important notices, plus a sharper compliance check.
IN-APP MESSAGES
• The app can now show the occasional notice when you open it — app updates, regulatory reminders, and time-critical information.
• Each notice appears once and is easy to dismiss. To re-read one, open Messages from the menu — it keeps the notices you've received until they expire.
• Prefer not to see them? Turn in-app messages off in Settings. Critical safety notices always show.
A SAFER 10-IN-24 CHECK
• A leg accidentally dated on the wrong calendar day can quietly under-count your rolling 24-hour flight time. The duty now flags a leg that looks misdated, so the number you're trusting is the right one.
RECENTLY
• 2.4 — Reorder your legs, and drag-to-edit to the exact minute.
• 2.3 — Drag to edit block-out/block-in and a duty's Show/Release on the Duty Visualization. Plus 10 in 24 on Apple Silicon Mac.
2.4.1 Jun 26
v2.4 NEW: Reorder your legs — and drag-to-edit to the exact minute.
REORDER LEGS
• Put your legs in the order you fly them: on a duty period, tap Reorder and drag the legs into place.
• And they now keep the order you enter them — an after-midnight leg (say a 0100Z leg added after a 2237Z leg) stays in sequence and rolls to the next day, instead of jumping to the top of the list.
DRAG TO EDIT — NOW PRECISE
• Fine control as you drag — slide your finger away from the chip edge to slow the adjustment down and settle on the exact minute. Stay near the edge for fast, coarse changes.
• Or set it after the fact — a −1 / +1 pill appears when you finish a drag, so a tap or two lands the precise minute.
• Stretch without running out of room — pull the first duty's Show earlier or the last duty's Release later and the timeline scrolls to follow, so long duty periods and overnight rests set in one motion.
Plus: Reorder, Move, and Clear are now one-tap buttons on each duty period.
RECENTLY
• 2.3 — Drag to edit: retime block-out/block-in and a duty's Show/Release right on the Duty Visualization, with a live time-and-limit readout. Plus 10 in 24 on Apple Silicon Mac, so Cockpit Sync can link iPhone, iPad, and Mac.
• 2.2 — Duty Visualization: your whole two-duty plan drawn to scale, with elapsed-time rulers, look-back brackets, tap-to-explain pills, an Extended Rest projection, and a dockable iPad layout.
2.4 Jun 23
v2.3 NEW: Drag to edit — change your times right on the timeline.
• Drag a leg's edge in the Duty Visualization to retime its block-out or block-in. The Show, Turn, and Release around it flex to absorb the change, down to the minimums you set — so the rest of the day stays honest.
• Drag the Show or Release edge to set a duty's start and end the same way.
• A live readout follows your finger: the new time, the segment's total length, and a heads-up the moment you bump into a minimum.
• Works in portrait and in landscape, where slanted grips ride right on the chip edges.
• New Minimum Show and Minimum Release limits in Settings, alongside your quick-turn minimum.
ALSO NEW
• 10 in 24 now runs on Apple Silicon Mac — so Cockpit Sync can link iPhone, iPad, and Mac over a direct, serverless connection.
Open the timeline with the bar-chart icon in the planner's top bar, then press and hold a grip on any edge to grab it.
RECENTLY
• 2.2 — Duty Visualization: your whole two-duty plan drawn to scale — Show, legs, turns, Release, and the Rest between duties — with elapsed-time rulers, look-back brackets, tap-to-explain pills, an Extended Rest projection, and an iPad layout you can dock where you like.
• 2.1.1 — Original one-time purchasers: tap Restore Purchases to unlock lifetime access. Thanks for being here since v1.
2.3 Jun 16
v2.2 NEW: Duty Visualization — a picture of your whole two-duty plan.
• Every part of the day — Show, each leg, each turn, Release, and the Rest between duties — drawn as a chip sized to its real duration. Long legs look long, quick turns look quick.
• Rotate to landscape for a horizontal timeline with a style all its own — and the view keeps your place when you rotate.
• On iPad, dock the timeline where you want it: a popup, a side pane, or a bottom pane that sits alongside the planner and updates live as you edit. Your choice is remembered.
• Elapsed-time rulers on each duty period and the rest gap let you read progress against the 14-hour duty limit and the 10-hour rest minimum at a glance.
• Look-back brackets show which legs are eating into a rolling 10-in-24 (or 8-in-24) window, and the exact window the rest calculation measures.
• Tap any ⓘ — on a ruler's closing pill or a bracket's label — for a plain-language explanation: what the number measures, the applicable limit, and where you stand.
• If the plan carries an exceedance, an Extended Rest chip shows the mandated rest after your final release — and why.
• Compliance colors match the planner — green, yellow, orange, red.
• Tap the pencil on any Show, leg, or Release chip to edit it without leaving the timeline.
• And a little crew humor on the turns and overnights — it rotates, so you won't see the same line twice for a while.
Open it with the bar-chart icon in the planner's top bar.
