Beautiful Planimetry vs EulerPad

Geometry doesn’t have to feel impossible. When my daughter first opened her geometry book, she looked at the page — circles, triangles, and lines everywhere — and sighed: “Dad, this makes no sense.” I knew that feeling. So I built a way to make geometry visible. With sliders, motion, and colour, she could see how shapes connect — how an angle changes a triangle, how circles hide perfect relationships, how formulas aren’t just rules but reflections of movement. That small idea became Beautiful Planimetry — an interactive geometry world where math comes alive. Instead of memorising formulas, explore how they work. Move a slider and watch a shape stretch, rotate, or reveal a hidden pattern. Suddenly, geometry isn’t about remembering — it’s about discovering. What you’ll find inside Included for free: - Circle Geometry: basics, inscribed angle, right triangle on diameter, law of sines - Circle Area: circle, sector, segment, ring - Thales’ Theorem: parallel lines crossed by an angle - Angle Bisector: see how angles are perfectly divided - Triangle Basics: triangle types, Pythagoras, law of cosines, inscribed circle in a right triangle, right triangle inscribed in a circle Unlock more with one in-app purchase: - Triangle Area: base × height, two sides + angle, Heron’s formula, equilateral triangle - Quadrilaterals: square, rectangle, parallelogram, rhombus, trapezoid, kite - Regular Polygons: triangle, square, pentagon, hexagon, octagon Why students love it - Visual learning — see shapes change in real time - Instant clarity — connect formulas to the figures they describe - Confidence boost — explore before practicing, so exercises feel easier Who it’s for - Students who want geometry to finally click - Teens tired of memorising without understanding - Parents and tutors who want to make math less stressful Beautiful Planimetry was born from a real story: a dad helping his daughter who struggled with math. What started as a simple app to make functions easier has grown into a family of apps that now includes geometry. Stop memorising. Start understanding. With Beautiful Planimetry, geometry becomes simple, visual, and — yes — beautiful.

EulerPad is a math practice workspace for iPhone and iPad. Pick a problem, work it out in your own handwriting, and tap Check — EulerPad's AI tutor reads your work and responds the way a good teacher would: what you got right, where a step went wrong, and what to try next. WRITE IT — ON SCREEN OR ON PAPER Math is learned by hand. EulerPad keeps the paper feel — a full-screen canvas, real ink, your own handwriting with Apple Pencil or your finger — and now works with actual paper too: solve it in your notebook, photograph it, and get the same read. Switch between the two whenever you like. Either way, you get the thing paper can't do on its own: feedback on your work itself, not just your final answer. FEEDBACK THAT TEACHES • Your whole solution is read, step by step — not just the answer • Feedback points to the exact step where things went off track • Mathematical notation is typeset cleanly, like a textbook • Still stuck? See a full worked solution A CURRICULUM THAT GROWS Practice Algebra, Geometry, Trigonometry, Calculus, and more, with new problems and topics arriving all the time — no app update required. YOUR OWN PROBLEMS Working from a textbook or worksheet? Bring the problem with you: type it in and solve it the same way, on screen or on paper, with the same feedback. FREE TO PRACTICE Every account includes a free daily practice allowance. EulerPad Premium, an auto-renewing subscription, raises it for heavier practice — manage or cancel anytime in Settings. PRIVATE BY DEFAULT No sign-up required — open the app and start solving. Sign in with Apple only when you want your work and credits to follow you to another device. Made for iPad and Apple Pencil. Now in your pocket, too. Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://eulerpad-2d8dac.gitlab.io/privacy.html
