Hiking & Approach Trail Tracking — GPS Navigation & Safety Ecosystem

Sendr is built for the entire mountain mission. Track backcountry hikes, alpine approaches, elevation profiles, and pack-in durations, all backed by an automated Safety Beacon.

Alpine Approach & Backcountry Hiking

Record comprehensive hiking telemetry including distance, vertical elevation gain, split paces, and calorie burn. Transition seamlessly from approach hiking to rock climbing mode.

Naismith’s Rule Pack-In Duration Calculations

Accurate time-to-crag projections based on trail distance, grade steepness, and terrain factors, helping you plan daylight and alpine starts effectively.

Active Safety Beacon Monitoring

Set up automatic emergency check-in beacons for remote backcountry days. If you fail to check in before your designated deadline, emergency contacts receive automated alerts with your last known GPS coordinates (requires cellular and GPS signal; not an SOS device replacement).

Smart Packing Lists & Rack Beta

Generate discipline-specific gear checklists tailored to your route length, weather forecast, and approach conditions so essential gear is never forgotten.

Frequently Asked Questions

Does the Safety Beacon work without cell service?
The Safety Beacon requires a cellular connection and GPS signal to transmit alerts. For deep wilderness without cellular reception, a dedicated satellite SOS device is recommended.
Can I record hikes and climbing in the same session?
Yes, Sendr supports multi-segment activities, recording your approach hike and climbing session within a single cohesive activity log.
How does Sendr calculate approach times?
Sendr uses Naismith's Rule with terrain adjustments, factoring in your historic hiking pace and vertical ascent rates.
