IronpointL

IronpointL is a landscape workbench that keeps two practical calculators side by side — a bicycle gearing tool and a triangle solver — with every result stored on your own device. In Ratio Deck you choose your chainrings, a cassette, and a wheel or tyre size, then read a colour-coded grid that pairs every front and rear combination. Switch the output between gear inches, rollout development in metres, or road speed at a cadence you set, and the whole matrix updates as you go, so comparing ratios is a single glance rather than a page of sums. In Angle Forge you pick a solve case — SSS, SAS, ASA, AAS, or SSA — type the three values you already know, and it works out every side, every angle, the area, and the perimeter, drawing the triangle to scale so the shape is easy to check. It even flags the ambiguous case when a second triangle fits. Save any result to your history, reopen it whenever you need it, or send it on as plain text. There is no account to make and nothing goes online — everything runs offline, on device.
