OS Maps App Review: Free & Paid Subscription

As digital maps become indispensable for outdoor adventures, the OS Maps App stands out as a crucial tool for explorers across the UK.

Designed for hikers, cyclists, and nature enthusiasts, this app offers detailed Ordnance Survey maps, offline GPS capabilities, and intuitive route planning.

Whether you’re trekking through rugged landscapes or enjoying a leisurely countryside walk, the OS Maps App ensures you have all the navigational support you need right at your fingertips.

Let’s get into the review:


“In my opinion, the OS maps app is the best hiking app on the market for planning and using for walks in the field. With the detailed OS Explorer and Landranger maps as well as offline GPS capabilities make the subscription well worth it.” – Alex Hesp-Gollins (Owner of

Apple App Store: 4.7/5 (55.5K Reviews)

Google Play Store: 3.1/5  (17.8K Reviews)

TrustPilot: 4.5/5 (2.1K Reviews)

🟢 Pros

  • Simple Route Management: You can easily create, track, and follow routes for hiking, running, cycling, and more.
  • Ready-to-Use Routes: Offers a selection of premade routes for various levels.
  • Unlimited Map Printing: Print as many maps as you need from the web platform.
  • Comprehensive Map Coverage: Access all 607 OS Leisure maps covering Great Britain and Northern Ireland, widely recognized and used by hikers and professionals alike, including the DofE, Scouts, the British Mountaineering Council, Armed Forces, Mountain Rescue teams, and many more.
  • Offline Map Downloads: Carry your maps with you without needing an internet connection while keeping live GPS capabilities.
  • Cross-Platform Compatibility: Use it on web browsers, mobile devices, tablets, and smartwatches.
  • Complimentary Access: Free access to the digital version of any paper map you own.

🔴 Cons

  • Limited Social Features: Offers fewer options for community engagement compared to some other options.
  • Geographic Limitations Outside UK: Its main functionality is restricted outside Great Britain and Northern Ireland, making it less useful for international trekers.
  • Learning Curve for Beginners: While OS Leisure maps are packed with detail, they might initially overwhelm new hikers. However, mastering these maps can significantly enhance your navigation skills.
  • Platform-Specific Complaints: There have been reports of bugs and issues, particularly in Android devices. Although this cannot be universally verified, it appears that the developers are actively working on updates and improvements to address these concerns.

MARCH 2024 App Update: The app recelty got a facelift with changes to the layout and display screens with the main to make things easier to access and more initiative to use. I personally don’t mind the new design, although some prefer the old layout.

Premium Subscription VS Free

The cost is simple – £34.99 per year (£2.92/month) 

This subscription gives you access to all 607 OS Leisure maps. Even if you use it just a handful of times each year, it is well worth the cost, in my opinion.

Cheaper option: If you only hike in a limited area, another option could be to buy a paper map, which comes with a digital copy that you can use on the app. You can identify the maps with a mobile download by the blue ‘Includes mobile download’ badge on the cover, allowing you to redeem the map. However, it’s not possible to view these maps via the website.

Here’s an overview of the main features of the App:

OS Standard Mapping Worldwide (Free)

The paths and tracks that are displayed on the standard OS mapping are not necessarily rights of way data complied from various sources which are not always accurate.

Standard and satellite mapping coverage is also available globally, not just within the bounds of the UK.

Plot, Record, & Follow Routes (Free)

Plot, Record, & Follow Routes
Plotting a walk on OS map via Shining Tor

Within the app or web app (on your computer or tablet), you can plan your route in advance and switch between devices when you get outdoors, where you can record the activity and easily follow the route. 

Global snap-to-path (Paid)

The snap to path feature allows you to dot points on the map in large distances and let the software align the exact route on the path making in more efficient and quicker than having to very closely plot the route over the path.

Import & Export Routes (Paid)
export gpx
Export GPX option for The Trinnacle Walk

Routes can be imported or exported using the GPX file feature, which allows routes to be compatible with almost any GPS device or software. 

Offline Download OS Explorer & Landranger Maps (Paid)

The primary feature of the paid Ordnance Survey maps app is the option to download Landranger and Explorer maps for offline use. This flexibility allows you to store and zoom into the UK’s maps on your smartphone, capturing all the details you’d find on paper maps, from contours to walls.

IMPORTANT: Ensure you download the route before you arrive, and check that it says ‘complete’. I’ve closed the app prematurely more than once, which meant I had to revert to the paper map in the field due to a lack of signal. However, this is exactly why carrying a paper map and compass is always a good idea! 🙂

If you purchase an OS paper map, look for the “includes mobile download” label, which will grant you access to some of these features.

GPS Tracking

If your phone is equipped with a GPS chip, compass (magnetometer), and motion sensor — features found in most smartphones and iPhones — it can accurately track your location on the map, even without a signal.

From personal experience, the app’s reliability in conditions of poor visibility has proven invaluable. This highlights its significance for safety and navigation in challenging environments.

You can print unlimited A4 or A3 paper maps, which makes it really easy to select just the tiles you need with the route already marked.

This way, you can easily slide the map into a sleeve, and off you go.

Here’s a great short video that discusses most of these features:


What is the best app for hiking in the UK? In my experience it’s @@Ordnance Survey and here are 5 reasons why 👇 1. How easy it is to plot a route The snap to path feature automatically ‘snaps, to the most direct path between two points, following existing trails, footpaths & public rights of way I can also plot a route on my laptop/desktop and it instantly becomes available on my phone📱 2. Offline availability Mountainous regions are notoriously signal back holes, but with OS Maps you can download whole regions as well as pre-planned routes so you will never get caught short again! 3. How easy it is to find routes The app has thousands of user generated routes readily available to download. You can easily search for routes by location and filter them by: -Difficulty -Duration -Rating -Type 4.How detailed and easy the app is to use You can choose between 3 different base maps (standard, topographic, and aerial) & you can set alerts for if you venture of your planned route. 5. The ability to print off A4 maps of your route that are too-scale This means you can have a back up when hiking which much cheaper, smaller, and easier than a standard physical map #hiking #hiker #hike #outdoors #explore #adventure #hikingadventures #hikingtips

Safety Considerations: Not Fully Relying on the OS Maps App

While the OS Maps App is a valuable tool for navigation, relying solely on any digital app can be risky, especially in remote or challenging environments. Here are essential safety considerations to keep in mind:

  1. Portable Charger: Always carry a portable charger. Digital devices can run out of battery quickly, especially in cold weather or when using GPS functions extensively.
  2. Paper Maps and Compass: Always have a paper map and compass as backups. They don’t require batteries and are crucial if your digital devices fail.
  3. Map Printing: Utilize the OS Maps App’s feature to print only the A4 sections you need. This can lighten your load while ensuring you have reliable, physical maps of the areas you’ll explore.

Adopting these safety measures will enhance your preparedness and ensure a safer hiking experience, keeping you ready for any situation where technology might let you down.

OS Maps App Alternatives

When exploring alternatives to the OS Maps online app for UK hiking, AllTrails and Komoot are notable contenders, each offering unique strengths and popular with a range of walker.

AllTrails: Community-Powered Trail Discovery

AllTrails Hiking App on the App Store

AllTrails shines with its vast trail database and user-generated content, featuring over 400,000 global trails. It’s user-friendly, with powerful search filters to match hiker needs by trail difficulty, length, and more, with some of the most detailed route photography and community advice.


  • Extensive trail options worldwide
  • Strong community interaction
  • Intuitive interface


  • Inconsistent detail across trails.
    Less focused on UK-specific hiking.

Komoot: Customized Outdoor Route Planning

kamoot Hiking app - Apple App Store

Komoot is renowned for its detailed, customizable route planning and offline map capabilities, ideal for both hiking and biking. It leverages community insights for enriched outdoor planning as well, although it seems to be slightly less popular than All Trails.


  • Advanced route customization
  • Useful offline navigation
  • Diverse activity options


  • Premium features require a paid subscription
  • Feature complexity might overwhelm beginners

Both apps enhance hiking experiences with distinct focuses: AllTrails on community-driven trail exploration and Komoot on personalized route planning, although neither I would say are better than OS maps in the UK due to the interior maps.
