Pythagorus doodlus vs Paper Maker

Solve any triangle with ease — instantly and visually. Pythagorus doodlus is designed for anyone who works with triangles every day: engineers, builders, surveyors, students, and curious minds. The app was originally created for a friend who is a carpenter and for my sister, an architect — and it shows. Every feature is built to be practical, intuitive, and genuinely helpful in real‑world situations. Enter any combination of sides or angles, and the app calculates the rest in real time. Watch the triangle update as you type or adjust values. And if a triangle is impossible to construct, the app doesn’t just say “error.” It visually explains why the triangle can’t exist and provides a clear, simple reason. Perfect for learning, teaching, or avoiding mistakes on the job. Features • Hand‑drawn design A unique interface that looks and feels like sketching a triangle on paper. • Interactive triangle editor Tap a side or angle to edit it, then enter its value using the built‑in keyboard. • Smart geometry engine Automatically solves triangles from any valid combination of sides and angles. • Invalid triangle detection If the values don’t form a real triangle, the app shows a visual explanation and tells you exactly why it doesn’t work. • Drag‑to‑reshape Drag the triangle’s corners to shape it freely before entering side or angle values — a simple way to visualize the triangle you’re working on. • Quick shortcuts Double‑tap an angle to toggle 90°, or reset values instantly. • Step‑by‑step tutorial A friendly guided walkthrough shows you how to edit sides, adjust angles, use shortcuts, and create new triangles. Whether you’re on a construction site, at your drafting table, or studying geometry, Pythagorus doodlus gives you a playful and powerful way to understand and work with triangles.

Paper Maker makes the paper. You choose the size, the margins, the grid and the header, watch it redraw as you adjust, and export a high-resolution PDF you can write on in GoodNotes, Notability, or anything else that opens a PDF. Label sheets print straight from the app. WHAT YOU CAN BUILD • Ruled, dotted and square grid pages, with spacing and line weight you set • Cornell note pages with a cue column and summary band • Weekly spreads and monthly calendars that are correct for a real month — leap years and your own first day of the week included • Daily time-blocked pages • Any page size: A4, A5, Letter, or your own custom dimensions LABELS (NEW) • Address labels, name stickers and file labels, printed at true size from the app • Pick a Letter sheet layout (5160, 5163, 5167), or type in the label size, count and margins in mm for any other sheet • Print one alignment test, then nudge until it lines up. The nudge is saved per printer and used only when the app prints (a shared PDF is never shifted) • Skip the labels you already used on a half-used sheet • The same text on every label, or a pasted list, one entry per label (up to 4 lines each) PRESETS Save a preset, come back to it later, adjust one number, export again. PRIVACY Everything is computed and drawn on your device. There is no account and no server. We collect nothing. The app sends no data out on its own; sharing a PDF or printing happens only when you do it. No subscription. No advertising. No analytics. No tracking. Pay once.
