Why do we regularly update our map files? Because thanks to thousands of OpenStreetMap editors, the maps are constantly getting better, like seen here. Do you contribute to OSM? Then show us some of your own favorite before/after map images in CoMaps!

And if you don't have any before/after images at hand: You still got some days to map before we start the next map generation 😉

#OpenStreetMap

Our latest maps with OpenStreetMap data from September 27 are now out. You can press "check for updates" in the app to see them and start downloading them.

Hi, I'm starting to try to use CoMaps in the Philippines, I'm realizing that there isn't much detail yet here. Not many restaurants, landmarks, etc. Is this due to lacking underlying OpenMaps data?

Hi everyone, big fan of the app.

I was wanting to ask about the subway view, is it only for subways?

I see that obviously the Glasgow Subway is included, which is obvious, but can Light Rail systems be included? I'm thinking about Edinburgh Trams, personally (which is treated more like a metro that goes on the road than a Tram) but also Manchester's Metrolink.

If the above systems are something that would be covered by subway view, would it be okay if I add Edinburgh?

When starting a track recording, is there some way to see the details of the recording while it is still recording? Maybe I just don't know how to but im organic maps you can just click the recording button at the upper right corner and get all the details like length, time, elevation gain loss etc. I would think that's a basic and important thing to see. If I start recording a hike or a run I would want to know how far I have come and how long it took me so far. Does comaps really not have that feature?

#OpenstreetMap

Some of us attended the lovely State of the Map conference in Paris at the end of last month. In this blog post we share how it went and what learned!

https://www.comaps.app/news/2026-09-14/comaps-at-state-of-the-map-2026/

Our Release 2026.08.31 is already out on iOS, F-Droid and as APK on Codeberg, including for use with Obtainium etc.

Unfortunately, the Google Play version is still in review, two weeks after submission and two support tickets later.

New features include the display of reviews from @mangroveReviews@mas.to (which you can create e.g. using @MapComplete@en.osm.town), and a new transport modes UI on iOS.

New maps with OpenStreetMap data from September 13 are now out. Press "check for updates" in the app to see them in the app!

I have 1 TB of storage on my phone, sometimes it's more than I know what to do with.

So I downloaded every map available in CoMaps. Every. Single. Country.

The result is about 92.1 GB of storage being taken up, for those who are curious

The thing is though, every time a new map update comes out, CoMaps makes me re-download all 92.1 GB of my downloaded maps all over again.

For example, let's say a new map update comes out, and instead of being 92.1 GB, it is now 92.2 GB. Even though there was such a small increase, all my maps from Afghanistan to Zimbabwe and everything in between have to be re-downloaded.

Not only is it annoying for me, but I feel like it strains CoMaps's servers when I tell it to download almost 100 GB of map data every week or two and I feel bad for it

So basically, when there's an update for some of your maps, it won't just grab the new information, it will also re-download all the old information it already had before it seems. Not sure if this is a bug or a feature with a valid reason for being implemented

Has anyone else noticed this or experienced this?

If you have tried Trek, a self-hosting tool for organizing your trips, you can now directly open CoMaps from it! https://github.com/liketrek/TREK/pull/1932

How often does the app upload the changes? It seems to me that it doesn't do it instantly but rather after hours or days, grouping everything you modified together in a single changeset

Edit: I tested it a bit and I realised that I had the mobile data off for CoMaps, which made the app keep everything in the cache until I connected to a WiFi. So, if connected to the internet, it creates a changeset with each edit that it then uploads within a second.

New maps are out now, with OpenStreetMap data from September 6. Press check updates in the app to start downloading them!

Is there a way to make CoMaps on iOS find contacts’ addresses on search?

That is, if I enter “John Doe” in the search bar it should show John’s address as entered in my iPhone contacts.

I feel like this must be there but somehow I can’t find it.

Would you label a chiropractors off e as a clinic or a doctor?

**IM SO GLAD THIS QUESTION WAS SO OFFENSIVE Y'ALL **
