A good app, with lots of routes and tracking. The one major drawback is that there is no easy way to organise routes. You can't create labels or folders, so everything sits in a single place. The titles also get truncated while looking at saved routes, so it can be very hard to find the saved or bookmarked route you are looking for. Please add folders and labels!!

Great App! now my goto app for walking and kayaking, use the record route feature, and like the published routes. Do get 'lost' in the app at times, but once you've learnt how it works, it's very good.

Great app, but I can’t get to premium any more

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.

Can’t cancel

Beware! I’ve tried to cancel multiple times and it won’t take. I’m going through Apple now. Don’t sign up for the free trial.

Beware!

Cancelled long before the 1 month “free trial” was up (given to me by a tour company I toured with) but they charged me anyway. Super disappointed.

Unable to cancel automatic renewal

There appears to be no way within the app to cancel automatic annual renewal once you’ve subscribed. Very frustrating. Either it doesn’t exist, or they deliberately Mae it hard to find.

Great maps, buggy app

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.
