Trailhead Hike Planner

Offline hike planner with Naismith pace math — calculate your ETA, pack your gear, hit the trail.

Trailhead Hike Planner takes the guesswork out of every hike. Enter your route distance and elevation gain, and the app instantly calculates your estimated finish time using the Naismith Rule — the classic mountaineering formula trusted by hikers and mountain rescue teams worldwide.

Choose from 5 built-in trail templates: • Day Hike Easy — gentle terrain, perfect for beginners • Half Day — moderate distance, out-and-back ready • Mountain — steep ascent with extended time buffers • Snow Hike — winter conditions with adjusted pace • Overnight — multi-day planning with camp stop estimates

Pack smarter with the 6-category gear checklist: Water, Food, Clothing, Safety, Navigation, and First Aid. Tap to check off items as you pack — the summary count keeps you honest before you leave the trailhead.

Fitness multipliers let you dial in your personal pace. Faster hiker? Slide the multiplier up. Recovering from an injury? Dial it down. The ETA updates in real time.

Switch between kilometres and miles with a single tap in Settings. All calculations update instantly.

Trailhead runs fully offline — no GPS required, no cellular signal needed, no account to create. Everything is stored locally on your device. Open the app anywhere, even deep in the backcountry, and your plans are always there.

Plan smart. Hike safe. Reach the summit.
