GPX Studio vs Stamptivity: Different Tools for Different Jobs
GPX Studio and Stamptivity both work with GPX files, but they do completely different things. Here's what each tool actually does and which one you need.
People searching for "GPX Studio vs Stamptivity" are usually trying to figure out which tool does what — or they've found one and want to know if the other does something the first doesn't.
Short answer: they do completely different things and aren't really competitors. You might end up using both.
What GPX Studio Does
GPX Studio is a route editing and analysis tool. Its core features:
- View any GPX file on an interactive map with elevation profile
- Edit routes: trim the start or end, remove a section, split into segments
- Clean noisy GPS data: remove outlier points, smooth the track
- Plan routes by clicking on a map (creates a new GPX)
- Merge multiple GPX files into one
- Analyse elevation, distance, grade
GPX Studio is about the route as a geographic object — what path did you take, how does it look on a map, can I fix the data.
What Stamptivity Does
Stamptivity is a GPS data visualization tool. Its features:
- Stamp (stamptivity.app/stamp) — turn your GPX/FIT into a shareable stats image with distance, pace, elevation, heart rate, and a route map. Export as JPG/PNG for Instagram, Strava, or social media.
- Overlay (stamptivity.app/overlay) — add live GPS gauges (speed, HR, map, elevation, cadence) to video footage. Load your video + GPX/FIT, position gauges, sync, and export as MP4.
- Merge — combine multiple GPX or FIT files into one track
- Convert — convert FIT files to GPX, TCX, JSON, or CSV
- Compare — load two activity files and compare speed, HR, and elevation side-by-side
Stamptivity is about presenting GPS data as content — what story does this activity tell, and how do I share it.

When to Use GPX Studio
- You want to see your route on a detailed map (OpenStreetMap, satellite)
- Your GPS file has noise (dropout, zigzag artefacts) you want to clean
- You need to trim the start or end of a recorded activity
- You're planning a route from scratch by clicking on a map
- You want to analyse grade percentages on a climb
When to Use Stamptivity
- You want a shareable stats image for Instagram or Strava → Stamp
- You want to add live GPS gauges to your cycling, running, or skiing video → Overlay
- You want to compare two activities on synced charts → Compare
- You need to convert a FIT file to GPX → Convert
- You have multiple GPX/FIT files you want to merge → Merge
A Common Workflow Using Both
- Record a ride with Garmin and a GoPro
- Export the FIT from Garmin Connect
- Open in GPX Studio — review the route, trim the first 2 minutes of warming up
- Export the cleaned GPX from GPX Studio
- Load into Stamptivity Overlay — add speed, HR, map gauges to the GoPro footage
- Export from Stamptivity — finished MP4 ready to upload to YouTube
The tools complement each other: GPX Studio for data quality, Stamptivity for presentation.
