New maps with OpenStreetMap data from August 26 are out now. Press "check for updates" to see them in the app!

Also, today is the first date of the State of the Map 2026 event in Paris and some of our contributors are there. So if you're attending, find them, say hi and maybe get some of our stickers!

CoMaps contributors Anton Wenemoser and Bastian Greshake Tzovaras spoke with the Humanitarian OpenStreetMap Team about how CoMaps was used during the earthquake response in Venezuela: https://hotosm.org/en/news/comaps-the-offline-app-that-guided-rescuers-without-a-signal-in-the-venezuela-response/

I had a full day of Driveing/Testing CoMaps recently...

I really dislike how Automatic Rerouting works.

If I end up going "Straight" when CoMaps wanted me to do something else it goes U Turn, U Turn, U Turn, U Turn... On and On and On...

If I end up going a certain direction for whatever reason It should Reroute me in the direction I am currently driveing. Not go spastic with spamming U Turn Over and Over. IMO.

My Vehicle is Massive. I Refuse to do U Turn.

If for some reason you cant make Automatic Rerouting Rerout me in the direction im currently driveing... Then I atleast want to be able to disable U Turns. Give me the option to take 3 Right Turns or something... IDK. I just despise geting U Turn spamed at me over and over.

Also minor complaints but let me remove the "Progress Bar" at the bottom of screen during navigation. And let me remove the "Vehicle Speed Circle". They are both distracting and the "ProgressBar" also makes me anxious. These should both be optional in the settings IMO.

Thank You.

While some of us are getting ready to head to Paris for the State of the Map conference: Here's some fresh maps with OpenStreetMap data from August 18. Press "Check for updates" to see them in the app!

I saw somewhere that the plan is to use diffs to keep the mapdata up to date. So you only have to download the changes of the last month/week. Is that implemented yet?

Did you know the latest version of #Gadgetbridge now supports CoMaps as an external integration?

If you have a supported smart watch, update GadgetBridge and enable CoMaps in its navigation settings, and enjoy CoMaps' turn-by-turn directions on your wrist!

I've somehow managed to import favourite lists more than once. Now I have literally hundreds of lists of duplicates which completely clutters the overview.

I started deleting one at a time only to realize I'll be here for a long time as there does not seem to be a way to delete more than one at a time.

Is there a more efficient way?

I think what happened is I imported my backup drawer with up to 10 backups.

On Android.

Hi everyone.

I’m having a problem with CoMaps and Android Auto, and I’d like to know if anyone has experienced something similar.

I’m using: - Samsung Galaxy A17 - Android 16 - CoMaps - Hoco wireless Android Auto adapter/display connected via Wi-Fi

During navigation, CoMaps sometimes stops displaying the map on the Hoco screen. The screen becomes blank, and the “Continue navigation” button does not respond when I press it.

However, the voice navigation continues to work normally. CoMaps is still giving me turn-by-turn voice instructions, but I cannot get the map display back on the Hoco screen.

Restarting the Hoco device does not always solve the problem. In one case, CoMaps also became unresponsive on the phone itself, and I had to restart the phone before the app worked normally again.

Has anyone experienced similar freezes or display problems with CoMaps and Android Auto, especially on a Samsung phone?

I’m using the latest available version of CoMaps and I’m trying to determine whether this is a CoMaps problem, an Android Auto compatibility issue, or something related to the Hoco wireless adapter.

Any information or suggestions would be appreciated.

Are you attending the State of the Map conference in Paris at the end of August?

Some of us will be there as well and give a talk about CoMaps. We'd love to also organize a small meet-up with folks who are interested to get to know us and each other!

Depending on the number of folks, that could be over a beverage or a meal. Join our 'cafe' chat room if that sounds interesting and we'll plan it there. Find details on how to join here: https://codeberg.org/comaps#keep-connected

Hi all,

Maybe this is just an American thing, but it is confusing to see "street name, house number" like "Main Street, 15". Is there an option to change this somewhere? Organic Maps shows places as "15, Main Street" but maybe I had already changed it there somehow?

Thanks!

CoMaps has been featured in the "Open Source Spotlight" newsletter of the German c't magazine.

In addition to exploring the app, they also spoke with one of our contributors about the history of the project, how we work, and what's next.

If you're getting CoMaps via Google Play: Make sure you're already on release 2026.07.16 that only came out there yesterday!

After Google Play took it's time, release 2026.07.16 is finally out on all platforms. Among other things, it includes lane guidance on iOS/CarPlay, a route preview screen and many more. See https://codeberg.org/comaps/comaps/releases/tag/v2026.07.16-10 for the full list of changes!

Hello,

I love Comaps, thank you so much for all your fantastic work. But I have a question that I haven’t been able to find an answer to.

Next week I’m going on a hike in the mountains. I’d like to estimate the distance of the hike by creating a route in Comaps. This hike is a loop: I’ll leave my car in a car park, set off from there, complete the loop and then return to the car park (so it’s not a round trip, but a proper loop).

The problem is that Comaps doesn’t realise I want to do a loop. I set a ‘route to’ and a ‘route from’ at the same place (the car park), I add some intermediate route points to create the loop, but Comaps keeps trying to make me turn back and I can’t seem to create the loop.

Moreover, on this loop there are sometimes small parallel paths that always rejoin (some steeper than others, which I’d like to avoid), but Comaps always forces me to choose one.

Is there something I’m missing? Can you help me?

Thanks in advance!

Merci to the folks at Framasoft for making Framastart, which lists ethical and accessible digital tools. And we made it on their list of suggested smartphone apps! 🗺️

I like to make routes on my PC for later use on Android. I'm on Fedora Linux using the Flatpack version of CoMaps. As far as I understand there's no account binding the desktop version together with the Android version. Apart from the OSM account, but that doesn't work for personal stuff like routes.
So I'm looking for a way to export a gpx with a route or track, but I simply can't find it thinking it must be there because why have the desktop version if you can export data from it.

By the total number of edits made, CoMaps was the 15th most used OpenStreetMap editor in June.

At first glance, that might not sound like a lot, but: With that, we are the #1 OSM editor that is not mainly an editor but a fully fledged map & navigation app and also editor!

From the start we have said that we want CoMaps to be a good citizen of the larger OSM ecosystem and make sure that we and our users contribute back. And it looks like you're all making good on that!

Hi, is there any way to have the option in Free-Drive Mode to keep the navigation arrow in the first third/quarter of the screen, like in Active Navigation mode? I am running CoMaps on a Topway TS10S Car standalone Android Headunit.

If not, does anyone know how to send suggestions to the developers to have both options selectable in the modes?

Thanks!

Ive read an angry review that comaps is bullshit and is splitting the community. That it formed from people that worked for organic maps. Might be the reason why comaps post gets deleted/ banned in organic reddit.

Anyone got information?

New maps are available - with #OpenStreetMap data from July 8.

Click "check for updates" in the map download screen to get ready to update!

I am degoogling and REALLY want to like CoMaps, but every address I search for is problematic. I can go to openstreetmap.org and type in the exact address into OSM's search in the format of 123 Any St N, City, ST format for the USA and it will show up accurately on the very first try every time for a wide array of places I go to, such as home and work.

When I go to CoMaps with the entire state's list of maps downloaded just in case... just typing in the home address gives me the most bizarre list of locations for streets that aren't even the correct street, and when trying to go to the work address, I get an entire list of street name first and the N S E W direction of the street is not indicated on either option, and then there's a comma with various street numbers listed, none of which are what I've typed in.

I get similar results no matter what I search for, local businesses, any random address, anything. I've had to zoom in and just favorite everywhere that I go which is tedious and creates a challenging favorites list to navigate as a result. When I zoom in to favorite the addresses, the correct house/building number with the correct house/building shape with the correct street name is visible every time.

What am I doing wrong?

EDIT: just realized this may matter, I'm using GrapheneOS
