30 days free — no card up front

Spend it on flight hours, not on software.

Charts, airspace, weather, NOTAMs and approach plates for student and general aviation pilots. $49.99 a year against $119.99 for the usual answer — and seventy dollars is about an hour with an instructor.

Why Threshold

Three things most weather apps get wrong.

Don't pay before you know

Most people who start flight training never finish it. Committing a few hundred dollars to planning software in month one, before you know which way that goes, is a strange place to spend money you could put in an aeroplane.

The whole country, offline

Every Class B, C, D and special-use boundary in the United States lives on your device. No spinner when you pan, no blank map without a signal, and it refreshes itself each 28-day cycle.

The difference is flying

$49.99 a year against $119.99 for the usual answer. Seventy dollars is roughly an hour with an instructor — which is a better place for it than a subscription, every year you keep training.

At a glance

Flight category, before you read a word.

Every airport on the map carries its current category, so the picture resolves before you tap anything.

Raw text and decoded tables

Raw METAR and TAF for the people who want it, decoded parameter tables for everyone else. Ceilings, visibility, wind components and present weather in plain English.

NOTAMs that don't lie to you

If the NOTAM system can't be reached, Threshold says so. It will never show an empty list and let you assume the field is clear, which is the one thing a briefing tool must never do.
