This looks great. Loved having an offline fully interactive map. Unfortunately when I close the app and restart it I have to download all 2.6gb of maps again as they don't seem to have been stored... gave up after 3 attempts and lots of fiddling with app permissions. Hopefully this can be fixed?

Very Nice App for offline UK map. Author very responsive to problems. I had to download Zoomstack from Ordnance Survey site as it wouldn't play ball over my phone's WiFi. I needed a none Google solution that would have minimal drain on the phone resources, this app does what I need, many thanks.

I downloaded the previous version and had to keep downloading the 2.6gb map data. Everytime it finished Downloading nothing would show and would start downloading again. Gave up for a few months. Downloaded the app again today. Downloaded 2.6gb data. Nothing showed. Everytime I start app it downloads map again. Given up

Very impressed with the app and level of detail on the map, farm names, house numbers etc. I used it to record gpx track, shame it don't give distance you have covered at the end of the walk. I downloaded map and moved it to SD no issues

This is a great mapping app, and ad free! Presently it is a bit basic but I have suggested some enhancements to the author and hopefully it will become even better in later revisions.

Very good app for using the free OS downloadable maps offline. One question there is a distinct detail difference between the cloud map and the offline map. Is it possible to have the same level of detail with the offline map?

Very impressed until I realised that the maps don't show footpaths. What a pity. 5 stars if you never walk but sadly useless to me.

Fantastic app. Be good to be able to save and share locations, will update to 5 stars then 👍 P.s. also, how come the online map data is superior? Can't the best map data be downloaded ?

Great app, but I also have the issue of having to re-download the map file every time I open the app. When can we get the new version that fixes this?

Sim. B. Jan 1, 2021     

Very good, but when the description said good for walking etc, I assumed the map would show public footpaths, but no. Are there more maps I can add?

Great maps with fantastic detail but I can't find out how to search for a place. Any clues from anyone please?

This is fantastic, but the download is very large and can't be moved to an SD card so I had to uninstall it 😕

Jan. S. Nov 23, 2020     

Well it's OK as far as it goes. No footpaths means it's of limited use away from town.

Really nice app. Would be great to see a legend that goes with this map.
