FAQ
How is this different from other map services?+
sampo. is built for making maps to give to someone. Most map apps save places as personal notes; sampo. turns your favorite places into a gift you can share instantly with a single URL. No account needed, ready in under a minute, and the order of spots and your one-line comments reach the receiver as is.
Can I make a map without an account?+
Yes. No email address or sign-up required — just open the page and start. If you log in, you can manage your maps on your own page.
Can I log the places I visit?+
Yes. With the Footsteps feature you can check in at places you visit (free, login required). Browse your log as a timeline, calendar, or map, and turn selected footsteps into a public map. Your log is yours alone — nobody sees it unless you publish it as a map.
Can I edit a map together with friends?+
Yes. Send an invite link from the edit screen and up to 4 people (including you) can edit the same map — great for trip planning or organizing events with co-hosts (Google login required). Maps being co-edited are visible to members only.
Can I view maps without signal?+
If you are logged in, any map you have opened once can be viewed offline — spot lists and comments included, even on remote islands or in the mountains.
Is it free?+
Completely free. Making, sharing, and viewing maps are all free.
How long do maps stay up?+
Maps currently have no expiration. Keep the URL and you can come back to it anytime.
How many spots can I add?+
Up to 100 spots per map.
Can I make a map private?+
Yes. Choose "private" when saving and nobody but you can view it. It will not appear in any listings.
