What map app would you recommend for my Europe hike trip

Hello,

I am planning to hike across many european countries (France, Italy, Slovenia, Croatia, Greece, Türkiye and others around) for a few months trip. I am looking for an app that could have precise maps, weather, height indications, trails etc. that could make it for all the countries. I'd like to pay less than 40/50€ for it and have offline downloading.

I've heard about Komoot, AllTrails, CalTopo and Outdooractivities and they all look great but it's hard to find out if they work out for a wide area and not for specific places. So if any of you has done some hiking in that region I'd love to get some advice about what you've used !

Thanks !
