Cluckium vs MotorSitter

Cluckium is the engineering geometry calculator built for the field. Whether you're sizing a manhole cover, calculating tank capacity, or verifying whether a lid can fall through its own opening, Cluckium delivers precise, instant results in a purpose-built dark neon interface designed for professionals who need answers fast. Choose from a comprehensive catalog of over 20 plane figures and 3D solids — circles, annuli, ellipses, sectors, segments, cylinders, cones, spheres, hemispheres, capsule tanks, cuboids, and more. Switch between metric and imperial at a tap, select your input mode (radius, diameter, circumference, or area for a circle — whichever measurement you already have on hand), and get every result you need: area, volume, surface area, perimeter, diagonal, slant height, and partial-fill volumes for tanks held vertical or horizontal. The Weight screen solves forward from dimensions to mass, or in reverse from a target weight back to any missing dimension, across nine common engineering materials including cast iron, steel, aluminium, brass, copper, and concrete. Why can't a circular manhole cover fall through its own hole? Cluckium answers this with its unique Fall-Through Solver. Select a lid shape — circle, Reuleaux triangle, Reuleaux pentagon, Reuleaux heptagon, square, rectangle, ellipse, or regular polygon — enter the dimensions, and receive an instant verdict: Safe — stays put, or Falls in, complete with minimum width, maximum width, critical ratio, and a clear geometric explanation. A Field Check mode lets you compare real cover and real opening sizes to confirm seating clearance and ledge overlap on site. The Constant-Width Gallery explores Barbier's theorem and the famous curves behind the UK 50p coin. Save any calculation or fall-through verdict to your Logbook, attach a site photo, add a title and notes, then export a polished rendered geometry card straight to your Camera Roll for inspection reports or project records. The Reference tab puts EN 124 load classes (A15 through F900), a complete formula sheet for every shape, and a 22-term engineering glossary at your fingertips — all fully offline, no account required.

MotorSitter turns your odometer into a clear maintenance dashboard. Add mileage readings and see how much distance remains before engine oil, filters, brake pads, tires, and custom service items are due. Once enough readings are available, MotorSitter can estimate due dates from your recent driving pace. Mileage-based and time-based intervals can be edited for each vehicle, so items that age by months are tracked even when the car is driven less. Keep service jobs, fuel stops, documents, and costs organized for any number of cars. Full-tank fuel entries can be used to calculate consumption, while partial top-ups carry forward until the next full-tank reading. The Log keeps your history together, Costs collects priced entries, and Garage lets you manage every vehicle, service plan, custom job, and document from one place.
