FitMerge joins an activity that was recorded as several files, for example when a watch died or you stopped by mistake, into one. No sign-up, and your files aren't uploaded: it runs in your browser. FIT, GPX and TCX in, FIT, GPX or TCX out. Free.

Hi, I'm the maker. Strava can't merge activities, and some of the tools I found for it wanted an upload or an account. FitMerge does the join in the browser, so the files stay on your device. I wrote the FIT reader and writer for this project instead of using a library. It asks before joining parts with a long gap and refuses files that overlap. It's free, with an optional Ko-fi tip link. Tell me which watches and apps' files break it and I'll look.
