A free hiking app may be enough to look up a route, record a walk or read another hiker's report. Downloading a map for the whole trip, exporting a track or sharing your location may have separate limits. Check those before you leave, especially if the route has little mobile coverage.
Plan features and prices can change. This guide gives you a way to compare them without relying on a price or quota that may be out of date. Use the provider's current comparison and your account settings to see what applies to you.
What free plans often include
Availability depends on the app, but these are common starting points.
- Online maps. With a connection you can open a map and look over the route. Check separately which maps you can download for offline use.
- Current location. The phone can receive satellite positioning signals without mobile data. The app still needs location permission and a usable map to show your position in context.
- Activity recording. Many apps let you record and save a track on a free plan. Look for separate limits on storage, access to older activities and export.
- Community and trip reports. Some apps let you browse public routes, photos and accounts of other people's hikes for free. Check the date and compare conditions with current notices.
These features can help you plan at home and keep a record afterwards. For navigation on the trail, check whether the map, route and your location still work when the connection drops.
When a paid feature may be useful
Three areas are worth comparing before deciding whether to subscribe.
Offline maps
Download the map for the entire hike before leaving, including your way back and plausible alternate exits. Some free plans allow a limited number of downloads or saved maps. YAMAP publishes separate download and storage limits, for example. AllTrails lists map downloads under Plus and Peak.
Open the saved map with mobile data and Wi-Fi off. Zoom in along the route and confirm that the trail, alternate exit and planned route remain visible. Carrier coverage maps and recent trip reports can help with planning, but signal on the ground can vary along the same route.
Detailed hiking maps
A topographic base map shows the shape of the terrain. Hiking map layers may add trail names, estimated walking times, water sources or warnings. Check what is included in the plan, who maintains each layer, and when it was last updated.
Where trails are faint or intersect, compare the app with an official map and current notices from the land manager. Treat an old water-source marker or hazard note as something to verify before relying on it.
Location sharing and emergency features
Some services charge for extra sharing options, contacts or notifications. Read how updates reach the recipient and when they can be delayed, especially if your phone has no connection. Agree what the recipient should do if you miss a check-in. Sending a location update and contacting emergency services are separate functions.
Choose for the hikes you actually do
List a few routes you expect to walk, how often you go and the sections where you may lose service. Then compare the features you would use on those routes.
A few outings on well-marked trails each year. A free plan may meet your needs if it covers the route offline. Download the map and check it before departure even on a popular trail.
Remote routes, ridge traverses or hikes in narrow valleys. Prepare offline coverage for the full route and alternate exits. A paid plan may be worthwhile if your free plan cannot hold the maps or layers you need.
Trips with a guide or companions. Agree what maps and emergency contact options the group will carry. Keep your own map and trip details accessible in case you get separated or someone else's device fails.
Using more than one app
You can use one app for trip reports and sharing and another for offline navigation. Compare their actual features and pick one as the main map and recorder for the trip.
Running multiple apps in the background with location tracking can draw extra power. Check the settings and test battery use before a long outing. Carry a charged power bank and the right cable if you will need them.
Take a paper map and compass and practise using them. They can still help if a phone loses power, gets damaged or cannot open the map you saved.
A checklist for comparing plans
Use the official plan page and the settings for your own account to check these points.
- Offline maps: which areas can you download, how many can you save, and how much space do they take?
- Map layers: which topographic or hiking-specific maps are included?
- Activity records: are there limits on storage, access to older tracks or GPX exports?
- Emergency and sharing features: who receives updates, what connection is needed and which plan includes each feature?
- Subscriptions: when does a trial or paid plan renew, and where do you cancel it?
Compare the full monthly or annual charge, the price after a trial and what happens to downloaded maps or older activity records if you change plans. Check the current terms for the channel where you subscribe, such as the app store or the provider's website.
Your next step
Open the plan settings for the app you already use. Download the map and route for your next trip and test them offline before leaving. Tell your companions which map and check-in arrangements you will use, and keep a paper backup with you.
