01 One home for your fleet

02 Hardware with context

03 A history worth keeping

LESS SEARCHING. MORE BUILDING.

The whole build.
All in one place.

The details add up. Rotor Ledger connects them, from the first part on your bench to the notes after your last flight.

01 / ORGANIZE

A place for every part.

Track what you own, where it lives and which aircraft it’s installed in. Keep purchases, serial numbers, condition and personal notes with the item.

Archive the item. Keep the history.

02 / UNDERSTAND

More than a part number.

Explore product backgrounds, sourced specifications, manufacturer resources and compatibility notes. Shared product knowledge stays separate from your personal records.

Clear sources. Visible unknowns.

03 / REMEMBER

Make every change traceable.

Save build snapshots, retain tune revisions and record maintenance. Compare what you documented before and after a change, with the context still attached.

Your records, preserved at a point in time.

AT THE BENCH. AT THE FIELD.

Your fleet goes
where you do.

A native experience on Mac, iPhone and iPad. Save locally, then keep your fleet connected with optional private iCloud sync.

macOS 14+iOS 17+iPadOS 17+

Photos that tell the full story

Add multiple photos from your camera roll or files. Adjust the crop, choose a cover and keep the uncropped copy for later.

Flight and battery records together

Log flight observations against a saved build and the pack you flew. Keep cycles, condition and recorded battery measurements in context.

Private by design

Your owned fleet uses private iCloud storage when enabled. The shared Rotor Library contains product information, separate from your personal notes and photos.

INTEGRATION / 01

Meet your build
where it’s tuned.

Keep Betaflight CLI files and tune revisions alongside your aircraft. The Mac preview also includes a read-only USB capture workflow.

BEFORE YOU FLY

A few useful details.

Is Rotor Ledger available in the App Store?

Not yet. Rotor Ledger is currently a development preview on registered Apple devices. TestFlight distribution follows the remaining device, controller and release checks. There is no public download at this stage.

Does this website connect to my fleet?

This is a product showcase with an interactive sample tour. Your real aircraft, photos and iCloud records stay in the native Rotor Ledger app.

Can I add custom or unlisted hardware?

Yes. Your inventory can reference a Rotor Library product or hold custom hardware. Personal specifications, notes, purchase information and photos remain yours.

What happens when I’m offline?

Entries save locally. With iCloud sync enabled, the app can sync when it becomes active, while it remains open or when you choose Sync now. Catalog photos may need an internet connection. Sync is not continuous background collaboration.

Does the assistant use an AI service?

The current assistant uses on-device rules and your recorded evidence. It does not send your fleet to a conversational AI service. A conversational assistant is a future possibility, not a current feature.

ROTOR LEDGER / DEVELOPMENT PREVIEW

Built for the details.
Ready for what’s next.

The foundation is in place. The next milestone is extended device testing, real Betaflight hardware validation and a carefully prepared beta.
