GPX tool for pump/ e-foil track analysis

Hey all, I created a free tool to analyse your pump or efoil tracks by excluding the times where you are not on foil by speed filtering.
It is quite basic, but works well to track max pump time and “in flight” time on a session.

Packaged app as EXE available, you can PM me

Hi Adam!

What a brilliant tool!
Thank you very much for sharing this with all of us!

Your instructions worked well and even with close to zero Python knowledge I could get it running with little effort!

The tool detects the segments nicely and the splitting works perfectly!

I am not sure if you are interested in Enhancement-Request?
Here are 2 points that would make the App even better:

A button to “Export All” that exports all of the sub-tracks in one zip file, excluding the ones that have been marked as “trash”
Heartbeat logging is missing from the created subtracks. This is very important for Pumpfoiling (it’s the main reason I am looking at my tracks currently)
It would be great if the Subtracks still had the original HeartBeat values!

Thank you already for considering this!
Best Regards,
U.Prinz

Hey, so basically this app is my benchmark for Ai coding tools. Latest Ai models can almost one shot the app build, test and deploy from a single prompt. Give it 3-6 months…

I recently did a web app version, it can be easily deployed, and is very lightweight.

You can test it here and install it locally on your phone or pc.

Thanks for the improvements suggestion, I will look into it.

Adam

Benchmarking GEMINI 3, 1 hour in, added HR info

edit, 3 h train ride with shitty wifi later, it is deployed, missing the trim feature but overall insane perf from gemnini 3
