Every flight,
measured.
Every thermal, found.

Drop an IGC file. We extract your glide ratio, climb rate, thermal centering, and XC score — then compare it to 402 pilots across 18,082 sites.

From .igc to
insights in 4 seconds.

We parse every B-record, detect climb phases with multi-signal thermal recognition, and score your XC — free distance, out-and-return, FAI triangle — before your wing is packed.

A logbook that
does the math for you.

Twelve precision tools that turn raw IGC into decisions. Each one is built to the standards pilots use in briefings — not marketing.

01

Drop-in parser

We read vendor dialects from Flymaster, Skytraxx, XCTrack, Syride, Alfapilot — every IGC, no exceptions.

IGC standard
02

Thermal recognition

Multi-signal detection blends vario, turn-rate, wind drift, and entry-exit ramps. No more false positives on ridge beats.

+0.5 m/s res.
03

XC scoring, auto

Free distance, out-and-return, FAI triangle. Every flight scored against WPRS rules the moment it lands.

FAI · OLC ready
04

Climb & glide metrics

Vertical speeds, glide ratios, turn dynamics — computed from your track. The numbers that matter, on every flight.

track-derived
05

Wind reconstruction

Post-flight wind profile at every altitude, inferred from your drift circles — no external sensor needed.

per altitude band
06

Progression analytics

Track how you grow over seasons, sites, and wings. Distance, airtime, climbs, conditions — slice it however you fly.

Takeoff database

Coordinates, elevation, orientation, best wind directions, current measurements from nearby stations, cam links. Community-curated.

Private link sharing

Each flight gets a secret, unguessable URL — only people you send it to can open it. No account needed to view, no public listing.
