At a glance: what each app actually is
Glidr is a navigation app designed for in-resort skiing and snowboarding. Its core capability is routing: you specify a destination on the mountain — a piste, a lift station, a restaurant, or any point of interest — and Glidr calculates a path across the piste network and guides you there with voice instructions. The announcements include piste names, turn directions, and distance to the next junction, using your phone's native text-to-speech engine with automatic audio ducking so music apps pause while Glidr speaks and resume afterward. Beyond point-to-point navigation, Glidr's AI Ski Day Planner takes your inputs — skill level, start time, goals like maximizing vertical or covering as many pistes as possible, lunch preferences — and generates a full-day itinerary with a step-by-step navigable route. Every feature runs offline after the initial map download, which matters at resorts where mobile signal is unreliable.
FATMAP is a terrain visualization and exploration platform that was acquired by Strava in 2023 and is now integrated into the Strava ecosystem. Its defining strength is the quality of its 3D mountain rendering: FATMAP produces detailed topographic models of mountains worldwide that show gradient, aspect, and exposure for any point on the terrain, including terrain far outside the marked piste network. For off-piste skiers and snowboarders, splitboarders, and backcountry tourers, FATMAP has been the go-to for studying a line before dropping in — seeing exactly how steep a couloir is, which aspect it faces, and what the exit terrain looks like. FATMAP also integrates activity recording through Strava, which gives riders the broader Strava community features and route-sharing tools. The trade-off is that in-resort piste-by-piste navigation is not FATMAP's focus, and the data-intensive 3D maps make offline use more limited.
Where Glidr wins
Voice turn-by-turn piste navigation. FATMAP does not appear to offer voice-guided routing across marked pistes. It visualizes terrain and shows your position, but it does not calculate a route from junction A to junction B and announce turns as you approach them. Glidr does exactly this — it is the only major ski app that does. For skiers and snowboarders navigating a large, unfamiliar resort and trying to find a specific lift or piste without stopping to study a trail map every few minutes, the Glidr vs FATMAP distinction here is fundamental.
AI Ski Day Planner. Glidr's planner produces a full-day itinerary and then navigates it, turn by turn, entirely offline. There is nothing like it in the FATMAP or Strava ecosystem. If you have one day at a large resort and want to make sure you ride the signature runs without backtracking or missing connections, the planner removes the guesswork. You can set it to prioritize easy terrain, maximum vertical, or scenic routes depending on your goals for the day.
Garmin and Apple Watch navigation. Glidr's Garmin Connect IQ data field shows the current piste, next turn, distance to the junction, and vibrates at each turn — giving riders hands-free navigation on their wrist. FATMAP does not appear to support Garmin watches. Glidr also has Apple Watch support for the same navigation data. For riders who prefer not to take their phone out on every run, this is meaningful.
Fully offline operation. Glidr downloads complete routing graphs and map tiles so everything — route calculation, voice navigation, map rendering — runs without any mobile signal after the initial download. FATMAP's 3D terrain visualization is data-intensive and requires connectivity for full-quality rendering. At high-altitude resorts where signal drops in the upper bowls, or for international visitors on roaming-limited data plans, Glidr's offline-first approach is a practical advantage.
Where FATMAP wins
3D terrain visualization. This is FATMAP's dominant advantage and nothing in the ski app market comes close to it. The 3D topographic rendering shows the actual shape of the mountain in detail far beyond what any 2D piste map conveys. You can inspect a specific couloir from multiple angles, check exactly how steep and on what aspect a particular off-piste line runs, and assess the exit terrain before committing to a descent. For any rider who ventures off the groomed network, this is genuinely invaluable information that Glidr simply does not provide — Glidr's maps are built for the marked piste network, not for untracked terrain.
Off-piste and backcountry coverage. Compared to Glidr, which is designed for the groomed piste network, FATMAP covers terrain that has no formal marking — remote ridgelines, backcountry touring routes, off-piste descents used by local guides. If a meaningful portion of your skiing or splitboarding happens away from marked pistes, FATMAP is a tool Glidr cannot replace. The gradient and avalanche-exposure overlays available in FATMAP add safety-relevant information that no other consumer ski app provides at the same quality.
Strava integration. If you are already a Strava user — which includes a large proportion of active outdoor athletes — FATMAP's integration means your mountain activities flow directly into your existing Strava history, segment comparisons, and social feed. There is no equivalent connection to Glidr's feature set. For riders who want their ski days as part of a broader annual activity record alongside cycling and running, the Strava ecosystem is a genuine draw.
Who should pick what
If you ski and snowboard primarily on groomed pistes — whether at a home resort you know reasonably well or at destination resorts you visit once a season — Glidr is the more practically useful app. It solves the real daily problem of not knowing which of three diverging pistes at a junction is the one that leads to your chosen lift, and it builds the whole day's itinerary so you do not end up on the wrong side of a large interconnected resort with no idea how to get back. For skiers and snowboarders who have ever had to catch a shuttle bus back to their hotel because they misjudged a traverse, that is a specific and real use case.
If a significant portion of your mountain time involves off-piste lines, ski touring, or backcountry terrain — and you spend meaningful time planning descents before you make them, studying gradient and aspect for safety and quality — FATMAP is a tool you will use on almost every mountain day. It is also worth noting that these two apps are highly complementary: Glidr navigates you through the lift system and across pistes to reach the entry point of your off-piste line, and FATMAP helps you plan and visualize the line itself. Using Glidr vs FATMAP as a binary choice misses the obvious point that the two apps serve genuinely adjacent use cases for the same rider. Many off-piste skiers and snowboarders who have tried both end up running both.
Pricing comparison
| Tier | Glidr | FATMAP / Strava |
|---|---|---|
| Free | Navigation, voice directions, offline maps, friends location sharing, Garmin/Apple Watch support | Basic terrain maps, limited route history (Strava free tier) |
| Paid | €1.49 Day Pass / €4.99 Weekly Pass — no subscription, no auto-renewal | Strava subscription ~€7.99–€11.99/month or a reduced annual rate (check App Store for current pricing) |
Pricing note: Strava's subscription cost covers the full Strava platform year-round, not just ski season use. If you already pay for Strava for cycling or running, FATMAP's mountain features come at no additional cost — which changes the comparison significantly. If you are evaluating Strava purely for ski use, the monthly cost is higher than Glidr's per-day or per-week planner pricing. Glidr's core navigation is free with no subscription required.
Frequently asked questions
Is Glidr better than FATMAP?
For in-resort piste navigation, Glidr is the stronger choice — it is the only app that routes you from point to point with voice turn-by-turn directions, and its AI day planner builds a full itinerary for your ski day. For off-piste exploration, backcountry planning, and terrain visualization, FATMAP (now integrated into Strava) has no equal. The honest answer is that the two apps serve different riders: Glidr for in-resort navigation, FATMAP for terrain visualization and off-piste lines. Many riders use both.
Does FATMAP have voice turn-by-turn navigation?
FATMAP does not appear to offer voice turn-by-turn navigation for in-resort piste routing. The app excels at terrain visualization and allows you to explore and plan off-piste lines, but it does not calculate a route across marked pistes and guide you along it with spoken instructions. Glidr is the only major ski app that provides this kind of real-time voice-guided piste navigation.
Can I use FATMAP offline?
FATMAP's detailed 3D terrain maps are data-intensive and require an internet connection to render at full quality in most configurations. Basic cached map data may be available offline, but the full FATMAP experience — especially the 3D rendering that is its signature strength — generally requires connectivity. Glidr downloads full routing graphs and tile data to the device so turn-by-turn navigation runs completely offline after the initial download.
Which is cheaper, Glidr or FATMAP?
FATMAP's full features are now part of Strava, which charges around €7.99–€11.99 per month (or a reduced annual rate) as of early 2026 — check the App Store for current Strava subscription pricing. Glidr's navigation is free; the AI Ski Day Planner costs €1.49 for a Day Pass or €4.99 for a Weekly Pass with no subscription or auto-renewal. For occasional skiers who only need the planner on specific trips, Glidr's per-use model is significantly cheaper than a year-round Strava subscription.
Can I use both Glidr and FATMAP together?
Yes, and for off-piste and backcountry riders this is a genuinely useful combination. Use FATMAP to study the terrain before dropping into an off-piste line — checking gradient, aspect, and exposure — and use Glidr to navigate the groomed piste network between lift stations and off-piste entry points. The two apps address different parts of a mountain day and complement each other well without overlap.
