I used them constantly. Not strava, but a heatmap leyer on the map in the [Alpinequest](https://alpinequest.net) app. If you're into topo maps and Android, that's the only app you'll need for the outdoor navigation. 🧭

It's not so easy to use but that's because there's so much options to set up.

Heatmaps saved me many times especially in winter times when many trails are covered with snow.
