Rope Rescue Calculator2026

Rope Rescue Calculator is a local utility for rope rescue training, outdoor teams, and high-angle work scenarios. It helps users quickly estimate common pulley ratios, forces, and angles.

Key features include:

1. Pulley ratio calculation: supports common 2:1, 3:1, 5:1 systems and estimates theoretical pull force and efficiency loss.
2. Anchor angle force: enter angle and load to view dual-anchor force distribution and risk tips.
3. Stretcher slope and hauling distance: calculate slope, rope length, and transport references from height difference and horizontal distance.
4. Equipment checklist templates: save training plans, rope length, pulley count, carabiners, and protection gear.
5. Local record archive: save calculation results by project for training review and offline lookup.

All data is stored only on the device. No login, no internet connection, and no personal information collection are required. It is designed for users who need a stable, low-maintenance, ready-to-use professional utility.
