## What is TailMark?

TailMark is a plane-spotting logbook that works entirely offline.

Type any US tail number and TailMark instantly tells you the manufacturer, model, category, and
engine type — no signal required, no waiting on a network lookup. That's because TailMark bundles
a real database of over 300,000 US-registered aircraft (built from the FAA's own public registry)
directly inside the app.

How it works:

1. Spot an aircraft and log its tail number. TailMark auto-fills the aircraft's details from the
   bundled database — or note manually if it's not in there yet.
2. Tag the airport, add a photo and notes if you want.
3. Build your life list: every unique aircraft you've ever logged, grouped by type and
   manufacturer, with how many times you've seen each one.
4. Keep your spotting streak alive day to day, and watch your stats grow — total sightings,
   unique types, unique manufacturers.

See where your aircraft have actually flown. Tap any sighting and TailMark plots that aircraft's
real flight paths over the last 30 days on a map — every leg it flew, where each one started and
ended — and shows its live position if it happens to be airborne right now. Flight data comes
from adsb.lol's network of volunteer ADS-B receivers.

Point your camera at the fin. TailMark reads the registration straight off the tail using your
device's own text recognition and fills in the aircraft for you. Nothing leaves your phone.

Earn your wings. Seventeen badges track the milestones that matter to a spotter — your first
sighting, ten unique types, five manufacturers, a rotorcraft, a glider, a dawn log, a night log,
a 30-day streak — with every locked badge showing exactly what unlocks it. Optional reminders
nudge you before a streak lapses.

A map of your own spotting, too: every sighting you've logged, filtered by today, this week, this
month, this year, or any single date.

See what is flying over you right now. Overhead lists the aircraft within 10 nautical miles of where you stand, closest first, with where to look (such as NE, 32° up), its altitude and distance. One tap logs it as a sighting, and aircraft that are new to your logbook are flagged. Overhead is free for everyone.

Overhead alerts (TailMark Pro) send a notification when a notable aircraft, or a type you have never logged, passes over a spot you save. Quiet hours overnight, at most five alerts a day, and you can turn them off any time.

TailMark Pro removes the daily limit on following aircraft live, and adds unlimited photos per
sighting, CSV export of your full logbook, and an optional digest that alerts you when
something notable is reported near an airport you track. Choose a monthly or yearly plan — the
yearly plan starts with a 7-day free trial. Flight history and the maps are free for everyone.

No account, no sign-in required — your logbook lives on your device.
