Arc & Arch Layout Calculator vs Dimemo

Arc & Arch Layout Calculator is the precision toolkit every carpenter, joiner, mason, stonemason, builder and DIY enthusiast needs to lay out perfect arches and curves on any job — without complex trigonometry and without ever pulling string from a nail. TWO PROFESSIONAL CALCULATORS IN ONE APP Large Arc Layout Set out a large-radius arc inside any confined space — an opening, a wall, a panel or a curved trim run. Enter the chord width plus either the rise (height) or radius and instantly see: • Sweep angle, arc length, slice and full-circle area • Inside arc mark-out — heights every increment from chord centre out • Outside arc mark-out with optional outer offset • An interactive set-out diagram you can pinch to zoom and drag to pan • A printable template with automatic A4, Letter, A3, A2 and A1 page-fit guidance • A bonus calculator that derives width, height, length and area from radius and sweep angle Gothic Arch Layout Design true masonry arches with mathematical precision. Choose equilateral, lancet or drop arches — the app classifies them automatically — and instantly receive every dimension you need: • Inner and outer radius, inner and outer height • Triangle chord and triangle drop for the gothic set-out • Intrados and extrados arc lengths • Setout mark-out heights from centre out • Voussoirs: full unit count per side, inner and outer arc per voussoir, plus a dedicated keystone diagram • Optional full-scale keystone and voussoir templates ready to print EVERY MEASUREMENT, METRIC OR IMPERIAL Every input switches instantly between Metric (mm) and Imperial (feet, inches and 1/16 to 15/16 fractions). Imperial inputs use clean three-wheel pickers — feet, inches, fraction — so a 6 ft 3 1/2 in chord takes seconds. INTERACTIVE DIAGRAMS YOU CAN ACTUALLY READ Every calculation is paired with a crisp, vector-quality diagram. Pinch to zoom, drag to pan, double-tap to fit, and use the live measure tool to read distances off the drawing. EXPORT TO PDF FOR THE WORKSHOP One tap exports a complete multi-page PDF: a tidy summary page with all your inputs and results, followed by every diagram on its own page — perfect for printing the template at full scale or sharing with the team. NATIVE iOS DESIGN • Built with SwiftUI for iPhone and iPad • Works completely offline • Saves your last inputs automatically • No accounts, no subscriptions, no ads • Respects Dynamic Type and Dark Mode Stop guessing. Calculate, lay out, print and build — accurately, every time.

Dimemo lets you write measured dimensions directly on a photo and keep them there. Jotting numbers alone in a notepad often leaves you wondering which measurement was which. Photos and numbers get separated — that’s the problem. Dimemo keeps both on one sheet from the start. ■ Snap, draw, and enter Photograph furniture, a window, or a wall on the spot (or pick from your library) and you’re in the annotation screen. Trace on the photo to draw a dimension line with arrows at both ends, then enter the value you actually measured and its unit. Choose from mm / cm / m / in / ft — your last-used unit is preselected. ■ Auto numbering keeps photo and list in sync Each dimension line gets a sequential number: ①, ②, …. Delete a line in the middle and numbers renumber automatically, so labels on the photo never drift from rows in the list. ■ Share photo + dimension list as one page Export the photo and the numbered dimension list as a single image or PDF. Send it to family, share it on site, or print it to take along — recipients can see which dimension is which without extra explanation. ■ Organize with folders Create folders such as “Moving,” “Kitchen DIY,” or “Site survey” to sort photos. Thumbnails show a badge with how many dimensions are on each shot, so the right one is easy to find. ■ Edit later Drag endpoints to fine-tune, move whole lines, edit values, delete, and undo. Pinch to zoom for fine detail. Besides dimensions, you can add text notes on the photo. ■ No automatic measuring Dimemo does not use AR auto-measure or scale conversion that infers other lengths from one dimension. Only values you actually measured with a tape (or similar) are recorded — so the source of every number stays clear. ■ Stays on your device Photos and dimensions are stored on-device and leave it only when you choose to export and share them.
