I also use it with my family for holidays and with friends for weekend hikes etc. I pay for the premium subscription which allows me to download routes if I want to give others a paper copy to follow. ### 1/5 — Can’t upgrade. No support available *2026-08-16, version 5.6.1* Can’t upgrade to premium as keep getting an error message to say “subscription linked to another account” even though I don’t have another account. Tried to contact support and it takes you to a broken webpage with a 404 error message ### 4/5 — Latest release *2026-08-16, version 5.6.1* Great app…but search option is just not working properly. Offers street names when searching for towns/villages!! ### 1/5 — Is this just a scam? *2026-08-16, version 5.6.1* Bizarre — it doesn’t seem to do anything at all. Can’t find trails whose names are right on the map on the screen. The support button goes to a dead page. All the reviews are from years ago. They say they do the US but it doesn’t seem so. The App Store page says it’s $5/mo and $25/year but it’s $50/year. ### 4/5 — Useful App *2026-08-15, version 5.6.1* On the whole, it’s a useful app. I like that you can download routes to use offline, that you can record your hikes. But it would be better if it automatically showed where you actually are when you open the app, rather than having to scroll across the whole English map to find your position. ### 1/5 — Payment Requirement *2026-08-14, version 5.6.1* You have to pay a subscription to use the offline maps. I’ve deleted the app as I’m not paying £35.99 per year. ### 1/5 — Keeps PAUSING *2026-08-13, version 5.6.1* This app keeps PAUSING so all your data gets skewed. You have to keep RESUMING. Surely, it’s an easy fix? But OS won’t sort it. ### 1/5 — Really useless for planning a route *2026-08-12, version 5.6.1* I can't understand why this app gets so much support. I'm a bright guy and you would think that a map navigation tool would require a FROM and a TO. Not this app! ### 1/5 — Shocking *2026-08-09, version 5.6.1* Constantly crashes on my iPad ## Frequently asked questions about OS Maps ### What does OS Maps do?
