If you’re going hiking in the UK and not taking this app on your smartphone then you are a fool. Definitely worth the cost of the premium version to get access to the detailed maps and offline maps. OS maps always had amazing accuracy and detail - now you can use gps on your phone to see exactly where you are among all that detail. Great for planning free form hikes to get you off the beaten path. Only thing the app can’t tell you is the condition of the trail or footpath you are going to hike on - huge clumps of stinging nettles are a real thing - but you can use the app to replay your hike on the fly to avoid whatever you encounter that you don’t want to deal with. All this for less than the cost of a single paper map - it’s a bargain!

Hi Jja76421, thanks for your review! We're pleased you're enjoying OS Maps!
Great app, but I can’t get to premium any more
MisterBiscuits1978
I travel to the UK every few years and love the OS maps app. It’s great for planning walks to historic sites in the countryside and the subscription price is very reasonable for a month at a time. I’m heading to the UK soon and I can’t upgrade to premium. My devices say I already have a subscription on my Apple ID, but I don’t. It asks me to log in with my apple account but there is no “log in with apple” option, only e-mail. So I deleted my account and created a new one with my Apple ID e-mail address and it still does the same thing. Apple doesn’t even show the expired subscription from the last time I went to the UK. I assume because I paid OS directly instead of through the Apple Store. Now when I try to manage my subscription from the web, the website just pushes me back to the app and I get the same “You already have a subscription with this device’s apple ID” error. Please add Apple ID login so this weird billing thing doesn’t come up any more, or bring back web-based subscription creation. Great great app, terrible subscription infrastructure :-( EDIT: I was able to renew by searching my e-mail for the subscription receipt from years ago, which had a “manage subscription” link there. That took me to the App Store and let me Resubscribe, even though the App Store wasn’t listing the expired subscription. Sounds like Apple made some changes to the App Store list of subscriptions that has broken your user experience for US subscribers.

Hi, thanks for the 4-star review and glad you're able to enjoy OS Maps again, as well as our new snap to path feature. We are currently looking at adding some functionality to add pins. If you'd like to talk more about what you are trying to use this for, as well as get involved in some user testing as we build this, please could you email CustomerServices@os.uk with a subject title 'App Store Feedback' and I'll ask our customer service team to look out for it and pass it on. If not, I hope you continue to enjoy OS Maps!
Major technical issues syncing to iPhone and I Pad
Dr Poston
When I originally installed the apps and upgraded to Premium, everything worked fine. I logged out, but could never log back in with my premium subscription, both on the website and on the smart devices. I was finally able to log back on to their website but only by changing my password, which is ridiculous. And when I used the new password on my iPhone and iPad, in both cases I received the message that an unexpected error had occurred. Technical support did their best to help but the issue remains unresolved. There’s another feature of the app that is very annoying (this was before all my technical issues). The screen has a window with the option to start navigation. I only wanted to look at the route, not navigate. Unfortunately this window takes up a significant part of the screen, blocking a large part of the map. For some unknown reason, you can not close this window, and tech help said that the app developers aren’t currently going to change it.All in all, it’s a great app when it worked for me, and most people don’t appear to have had the problems I’ve experienced. I hope that tech people read this and do some more development work.

Hi Dr Poston, we're really sorry you experienced this issue. We are aware of these issues, and will be updating the app very soon to address them, please look out for the update and let us know if this resolves the issues for you.
Great maps, buggy app
SW-SW
I’ve used the os app for years and os maps for even longer. The maps are outstanding, but the app is too unreliable to count on. Unlike other mapping apps where you can work in an offline mode, when there is a problem with the os servers, you are logged out and unable to access your downloaded maps. This can be a critical problem, so I consider the os app to be more of a planning tool than something to rely on when I’m outdoors. There are several other buggy aspects, but most can be worked around. And as a planning tool, the os app is very helpful. It’s worth having just for the convenience of having the excellent os maps at your fingertips.
We’ve given your OS Maps app a fresh new look with a redesigned map selector, added a new Outdoors Map for Ireland, two new US Maps from the U.S. Forest Service and National Park Service and made it easier to find the right route for your next adventure. Plus, we’ve squashed bugs and made things better behind the scenes. Update now and get exploring!
