How It Works

Three Steps to Stunning Telemetry

01

Drop Your Video

Load any GoPro or DJI video. Telemetry is extracted instantly - GPMF for GoPro, SRT for DJI. No conversion needed.

02

Explore & Customize

Browse your GPS track on a map, analyze charts, arrange overlay gauges, sync with activity data from your watch.

03

Export & Share

Render your overlay as a video, export GPS data as GPX/KML, or reinject metadata back into your edited footage.

What To Know Before You Buy

Clear answers about licensing, supported footage, exports, and what the free version actually includes.

No. All telemetry extraction and overlay rendering happens entirely on your device. The only feature that needs internet is loading map tiles for the GPS visualization and even that can work with cached tiles.

GoPro Hero 6 through Hero 13, GoPro Max, GoPro Fusion, DJI drones (Avata, Mini, Air, Mavic) via SRT extraction, DJI Osmo Action cameras, and Insta360 cameras. Any camera that embeds GPMF or SRT telemetry is supported.

Free gives you full telemetry extraction, interactive maps, charts, stats, the 3D globe, and a starter overlay set with speed, altitude, compass, timer, text, image, and info bar gauges. Export stays available while you keep no more than 1 overlay active. Pro unlocks all 13 gauges, unlimited custom presets, baked video export, overlay file package export, KML/GeoJSON/VIRB export, activity sync, 360° viewing, Reinject Studio, and the 20 GB file limit.

No. The Android Pro key unlocks the same Pro edition gates in the app: all gauges, unlimited overlays and presets, baked video export, overlay file package export, advanced export formats, activity sync, the 360 viewer, and Reinject Studio. The difference is the implementation path: Android uses native file picking, saving, playback, and on-device processing where the desktop build uses the desktop runtime.

Each license can be activated on up to 2 devices (e.g., your desktop and laptop). If you need to move to a new device, you can deactivate from the old one first.

You download the app separately for free. The checkout sells a one-time license key that unlocks the paid limits on Desktop, Android, or both. VAT is already included in the displayed prices.

No. Both the Desktop Pro and Android Pro licenses are one-time payments. You get lifetime updates. I believe creators shouldn't pay monthly for tools they own.

Yes! Pro users can render the overlay directly into the video file. Choose H.264 or H.265 codec, select resolution (up to 4K), and export. Pro also unlocks the separate overlay file package export if you want reusable overlay assets for external editing workflows.
