RythoX

Rytho is a two-in-one field controller for people who move cargo and sail downwind. One neat vintage workspace, two very different calculators and every answer ready to save or share.

Cargo Fit answers a warehouse question: how many boxes can actually fit in it? Enter the length, width, height, and weight of your box, then set the pallet footprint, stack height, and weight limits for a pallet and a truck. Rytho tries each box orientation, packs it onto the pallet, and shows boxes per layer, boxes per pallet, and boxes per entire truck, plus the loaded weight, cube used, and whether height or weight is the real limit.

Sail Wind answers a question on the quay: how hard does the wind pull? Enter your sail area and wind, either as Beaufort force or in knots, then adjust the drive coefficient and lever arm. Rytho calculates the aerodynamic force on the sail in Newtons and kilogram force, and estimates the load on the sheet.

For both tools: a live ledger that updates as you type, a saved history that you can filter and reopen, and sharing with one tap. No login, no clutter, all on one screen.
