Your ride had the numbers. Now your video does too.

Overlayer adds a GPS overlay to your videos, right on your phone. Put your real speed, altitude, distance, gradient, heart rate, cadence, power, temperature, G-force and more on screen as live telemetry gauges, 15 readouts in all, and export a video that shows exactly how fast, how high and how hard. It's a speedometer, map and stats overlay for any video: no computer, no editing software, no account.

ANY CAMERA, YOUR DATA
• Works with any MP4 or MOV video: action cameras, phones and more
• Add your activity as a GPX or FIT file from your sports watch, bike computer or tracking app, with heart rate, cadence, power and temperature
• Turn a GPX track into a GPX video overlay in a few taps
• Cameras with built-in GPS fill in some of the data by themselves, lined up to the second
• SRT flight logs line up with their video on their own
• Syncs the data and the video automatically, or by matching one moment by hand in seconds

BUILD YOUR OWN GPS OVERLAY
• 19 gauges: big numbers, speedometer dials, bars, an altitude chart, a route map, a compass, heart-rate zones and real aviation and motorsport instruments in five finishes
• A simple speed overlay or a full telemetry dashboard: you choose what shows and where
• Add a speedometer to your video, a heart rate overlay, an elevation profile or a live map of your route
• Drag, pinch or slide each gauge exactly where it belongs, in any colour
• Or start from a ready-made style: Clean, Race Dash or Broadcast, each in several colourways
• Moments: pop-up cards for your top speed and other highlights, at the second they happened
• A finish card at the end with your best numbers
• Fix bad GPS points, trim the activity and smooth the data, with undo for everything

QUALITY THAT MATCHES YOUR CAMERA
• Exports at your video's own resolution and frame rate, up to 4K and up to 120 fps
• Keeps your video's sound
• Vertical and square versions for social media, choosing which part of the frame to keep
• Rendering carries on while you use other apps

A TELEMETRY VIDEO EDITOR IN YOUR POCKET
Desktop telemetry software means a computer, a long export and a learning curve. Overlayer does the same job on your phone: open your video, add your GPS data, and share an action video with real numbers on it in minutes. Great for POV footage, onboard videos, travel clips and workout videos.

IF YOU RECORDED IT WITH GPS, IT CAN GO ON YOUR VIDEO
Whatever you do outdoors, Overlayer turns the data from your watch, app or camera into a clean speed and GPS overlay that looks made for TV. Show your speed on video, your altitude as you climb, your heart rate as you push, and your route on a map, all in sync with every frame.

PRIVATE BY DESIGN
Overlayer has no internet access at all. Your location, heart rate and videos never leave your phone. No account, no ads, no tracking, and it works with no signal.
