The rigging math, done right.

Fast, tested rigging and lifting calculators for the jobsite — 100% offline, on your device, no account, no tracking. Imperial and metric. Pay once for the Studio, if ever.

What it does

• Sling tension & load-angle factor, working load limit by hitch, D/d bend efficiency.
• Center of gravity and crane capacity — deterministic, tested math.
• A Studio to save your gear and lift plans (one-time Pro unlock).
• Enter your own equipment ratings from the tag — Rigwise hosts no stale sling database.

Safety

Rigwise is a calculation aid. Verify every result against the manufacturer's tag, the load chart, and a qualified person. It is not a substitute for an engineered lift plan or professional judgment. Rigging is inherently hazardous; the user is solely responsible for the safety of any lift.
