I upload calibrated PDF maps to it. Free version allows for that (just one at a time for the free version). Works like Avenza in that way.

I’ll have to check it out. THank you!

Yeah. The lack of an Android option did not help. OTOH it’s a one person shop.

Still looking for a Gaia replacement. Some people have kindly suggested some replacements here, by email, or other social media.

Thanks for sharing your experience. I’ll have to check out your suggestion.

The main loss for Avenza is the sunsetting of the map store. But I’ll have to check it out for sure.

My large datasets are JSON overlays, e.g. all protected areas in Spain and Portugal (created from shapefiles), all of Spains 13k picnic areas, 15k springs, 51k public drinking fountains (scraped from OSM) – you get the idea.
For your tracks and waypoints you’d use GPX. Mine are only temporarily in Guru and then go into Garmin Basecamp, soon to be replaced with QGIS. So I have no experience with how Guru handles years’ worth of those, but based on my experience with overlays: probably just fine.

I haven’t done a named route in many years and Far out came after that time period. I used it for the GDT in 2018 but other than that, everything I the past decade has been DIY routes, modified non-thru hikes of others (Jamal Green), or Brett Tucker’s NNML. No Far Out for those routes. 🙂 More seriously, I don’t have much experience with the app to give a meaningful summary as it’s something I’ve only used once about 8 yrs ago.
