The Product

Built for the long run, not the engagement loop.

Record
Precise GPS with bearing lock
Dual-frequency positioning when your watch supports it. Live bearing, pace, elevation, and heart rate on one uncluttered face.
Maps
Offline maps, real maps
Vector tiles from OpenStreetMap + topographic overlays. Download a region, leave your phone in airplane mode, still see where you are.
Analyze
Splits you can read
Pace, grade, and effort side by side. No score. No "fitness age." Just the numbers your watch already captured, shown well.
Own
Your data, your files
Every activity exports as GPX and FIT. No cloud lock-in. Import from Geonaute, Garmin, Coros, or any GPS watch that speaks standard formats.
Analyze

Numbers that respect your time.

Elevation, grade, pace, heart rate — every metric your watch recorded, plotted without noise. Hover any point; read exactly what you did there. No trophies, no streaks, no engagement hooks.

The rescue

Your .g2log files
are not a dead format.

When Decathlon retired Geonaute Connect, thousands of athletes were left with a folder of .g2log files nothing could read. Azimut started as a decoder for that format. Drop the files in — every run, every coordinate, every heart-rate sample comes back.

We don't pair with the watch. We read the files it already produced.
2011Decathlon launches the Geonaute line.
2019Geonaute Connect, the desktop companion, is deprecated.
2023Users can still plug the watch in — the .g2log files come out, but nothing reads them.
2025Azimut ships a .g2log decoder. Years of runs become visible again.
