## What is Thermik?

Relive your tracks in 3D. Thermik turns the IGC, GPX and KML files from your vario, watch or bike computer into a replay over real terrain and aerial imagery: thermals, glides, climbs and descents. It keeps a logbook of every flight, hike, ride and ski tour.

• 3D replay over real terrain, coloured by climb, altitude or speed, or plain 
• Chase camera, an altitude profile to scrub through the track, live altitude, climb and speed 
• Logbook: import a whole folder, a ZIP or single files from the Files app; sites grouped by launch, yearly totals; fix the site or glider name after the fact 
• Open IGC, GPX, KML and KMZ straight from WhatsApp, Mail or Files 
• Share a story picture or a flyover video with your stats 
• Export GPX with true altitude, KMZ for Google Earth, or the untouched original IGC (signature intact for XContest and DHV-XC) 
• Sharp national aerial photos in Austria, Switzerland, Bavaria and France; Sentinel-2 cloudless everywhere else 
• Works offline: terrain is downloaded once per track, only when you tap Download 
• Backup and restore of your whole logbook in one ZIP file

No account, no ads, no tracking. Your tracks never leave your iPhone.

Made for Skytraxx and every other vario, watch or app that writes IGC, GPX or KML.

## Version history (last 5 releases)

### 1.4 — 2026-11-09

• Altitude profile over distance for hikes, bike rides, ski tours and drives: a long break no longer draws a flat stretch (flights keep the time axis)
• Chase camera: in deep valleys and canyons the camera tilts up so the terrain never hides your position, in the replay and in shared videos

### 1.3 — 2026-10-31

• Place names: an activity whose terrain is already downloaded no longer asks to download again; missing place names are fetched quietly in the background and appear when they arrive

### 1.2 — 2026-10-29

• Import more KML files: timed position pins, as flight trackers export them, and plain route lines
• New activity Plane with its own logbook tab: a track from an airliner or a small plane is recognised and stays in the air in 3D
• Long tracks: the shadow under the line now stays close to the terrain

### 1.1 — 2026-10-28

• Every screen turns to landscape: a compact logbook, and a flight screen with a side panel next to a full-height 3D view
• Share video: new Cinematic camera with orbits, a dive behind the glider and a calm chase, 30, 45 or 60 seconds
• During Play, drag to turn the camera around the glider, pinch for distance, double-tap to swing back behind
• New activity Drive; walks, bike rides and drives are drawn on the terrain
• Logbook: one filter for activity and pilot, editable start time, durations with units
• Numbers follow the app language, with grouped thousands
• Safer import, restore and backups, plus many fixes

### 1.0 — 2026-10-28

No release notes.
