Fontavio Reviews and Details

Questions & Answers

1. What makes Fontavio unique?

   • One free map for every water and sanitation service: drinking water, fill-up taps, toilets, showers, laundry, campervan dump stations and marina pump-outs.
   • Made for people on the move: campervan and boat people, cyclists, runners, hikers and travellers.
   • 650,000+ places across Europe, the US and Canada, 50 countries in total, mostly from OpenStreetMap.
   • Users can see what is closest or pick a place on the map, then follow the compass or use navigation.
   • Water marked as not drinkable says so, and a place nobody has confirmed in a while says that too.
   • Details, photos and reviews on places, plus tags for wheelchair access and changing tables.
   • No account needed to browse, and every filter is free.

2. Why should a person choose Fontavio over its competitors?

   • Competitors each cover one kind of place or one kind of traveller: parking, toilets, drinking water refills, or overlanding. Fontavio puts all the water and sanitation services on one map.
   • It works alongside parking apps, so users do not have to give anything up.
   • Every filter is free, with no account and no paywall on the map.
   • It shows how reliable a place is: non-drinkable water is labelled, and places nobody has confirmed lately are marked.
   • User location is never stored on the server.
   • Users can add missing places, fix details, and confirm in one tap that a place still works.
   • An optional Pro plan (€/$ 1.99/month or €/$ 9.99/year, 7-day free trial) adds offline maps, a route planner, and private notes.

3. How would you describe the primary audience of Fontavio?

   • Boaters who need a pump-out or water at the marina.
   • Cyclists, runners and hikers who need a fountain on the route.
   • City travellers and locals looking for the nearest toilet, a refill, or a laundromat.
   • Parents who need a toilet with a changing table, and users who need wheelchair-accessible places.

4. What's the story behind Fontavio?

   Fontavio started with a problem in a van. The founder, lived in a van, and the apps he used mostly showed places to sleep. What he needed most days was somewhere to fill an empty water, use a toilet or take a shower, and there was no app made just for that. So he built one: a solo developer from Turku, Finland, working alongside a full-time job and keeping costs as low as possible. The map started from OpenStreetMap, which already holds hundreds of thousands of these places, and grows with the people who use the app. Fontavio launched on Android first and on the App Store on 9 October 2026.

5. Which are the primary technologies used for building Fontavio?

   • Flutter, for the Android and iOS app.

   • Cloudflare in front of the API, and Cloudflare R2 for photo storage.
   • Astro for the website, which has pages for cities and countries.
   • Docker and nginx on a small server in Europe.
   • Google AdMob for ads and in-app purchases through the Apple and Google stores.
