iPhone
Plan your backcountry nutrition with precision. Calculate calorie needs based on terrain, elevation, pack weight, and your body. Build a meal pack to match.
Know exactly how many calories you'll burn on every mile of your trip — based on the actual terrain, your pack weight, and your body. MTNMetrics is precision nutrition planning for backcountry hikers.
Stop guessing how much food to pack. Whether it's a weekend overnighter or a week-long traverse, MTNMetrics calculates your day-by-day calorie and macro needs using published metabolic research — not generic estimates.
HOW IT WORKS
Draw your route on a high-fidelity 3D terrain map or import a GPX file from your favorite planning apps. MTNMetrics analyzes every segment of your route — grade, elevation gain, elevation loss — and combines it with your body composition and pack weight to calculate precisely how many calories you'll burn.
Then build a meal pack matched to your trip's calorie needs. Browse a curated food catalog, filter by dietary needs, and track calories, protein, fat, carbs, and pack weight as you go.
KEY FEATURES
▶ Terrain-Aware Calorie Calculation
Per-segment metabolic rate estimation using the LCDA equation (Looney et al. 2022). Your calorie needs change with every hill and every pound in your pack — MTNMetrics accounts for that.
▶ Day-by-Day Nutrition Breakdown
Multi-day trips are partitioned into hiking days with individual calorie and macro targets. Day 1 might need 4,200 cal. Day 2 might need 5,100. Plan accordingly.
▶ Meal Pack Builder
Browse meals by category, filter for dietary needs (vegan, gluten-free, dairy-free), and build a pack with real-time calorie and weight tracking against your trip targets.
▶ Route Authoring
Draw routes with snap-to-trail, place waypoints, or import GPX files from your favorite route planning app.
▶ 3D Terrain Maps
Topographic maps with contour lines, hillshade, satellite imagery, and day/night themes. Toggle public lands boundaries to see land ownership at a glance.
▶ Personalized to You
Calculations factor in your weight, height, age, sex, and body fat percentage. Your calorie needs are unique — your plan should be too.
BUILT ON SCIENCE
MTNMetrics uses the LCDA equation from peer-reviewed metabolic research (Looney et al. 2022) combined with Tobler's hiking function for speed estimation and Santee grade adjustments. This isn't a generic "calories per mile" calculator — it's a biomechanical model that accounts for how your body actually works on varied terrain.
PLAN SMARTER, PACK LIGHTER
Every ounce matters in the backcountry. MTNMetrics helps you pack exactly the right amount of food — no bonking on a pass, no hauling dead weight down the trail.
