Pipe Rack Designer
Read full descriptionHide full description
Design shelves, racks and frames from single steel pipe — then get the exact cut list and every fitting you need to build it. Enter width, depth, height and the number of shelves. Pipe Rack Designer instantly builds the structure and hands you a parts list you can take straight to the hardware store: pipes grouped by length and count, joints grouped by shape and count. SEE IT IN 3D • A live 3D model of your rack. Drag to rotate, pinch to zoom, tap to add or select a shelf. • Tap a shelf to move it up or down, or turn any of its four sides on and off — so you can build open-front designs like a firewood rack. • Open the model full screen to check the structure from every angle. TWO WAYS TO JOIN, COUNTED CORRECTLY • Clamp type: pipes are never drilled through — full-length pipes are laid alongside each other and held with right-angle and swivel clamps. Overhang and end caps are counted. • Screw-joint type: pipes slot into cast joints. Choose which member runs through (posts or beams); the others are split, and the split lengths and counts appear in your parts list. • Corner fittings are chosen by their real shape — L, T, 3-way corner, 4-way and 5-way — not lumped into one. BUILT FOR REAL BUILDS • Standard 48.6 mm single pipe • Base plates for free-standing legs, saddle bands and rafter clamps for shelf boards, end caps for exposed ends • Sloped-roof mode: set different front and back post heights for a slanted top • Copy the whole parts list as text for your shopping trip HONEST AND OFFLINE • Works completely offline. No account, no ads, no subscription. • One-time purchase. • Your designs stay on your device. • iPhone and iPad Whether you are building storage shelving, a workbench frame, a firewood rack or a sloped-roof structure, Pipe Rack Designer turns a few measurements into a buildable pipe-and-fitting plan.

Verdict
The clearest difference is update cadence: Pipe Rack Designer at fortnightly against LunaSolCal's every 2 months. Pipe Rack Designer also leads on price ($3.99 vs $4.99). LunaSolCal's advantage is chart position (#195 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
