Build the run segment by segment, the way the cable meets it. The app gives the tension at every step, the sidewall pressure at every bend, the jam check, the puller and the lubricant, and writes the pull plan as a PDF.
The app’s own example, every screen in order, 27 steps.
STEP 1 OF 27The example opens filled in: the reference pull, with the answer pinned at the foot of the screen.
STEP 2 OF 27The system, then the conduit: 2 inch rigid, standard 90s.
STEP 3 OF 27Pulling: Polywater J, the IEEE 525 sidewall limit, the weight correction and any cable hanging at the reel.
STEP 4 OF 27The run cleared, ready to build.
STEP 5 OF 27Segment 1: straight up 30 feet from the reel.
STEP 6 OF 27Segment 2: a 90 to level, heading forward.
STEP 7 OF 27Segment 3: straight 90 feet, level.
STEP 8 OF 27Segment 4: a 90 to the right.
STEP 9 OF 27Segment 5: a 90 down.
STEP 10 OF 27Segment 6: straight down 30 feet. The answer: 279 lb, 306 lb/ft.
STEP 11 OF 27The run, drawn: each bend with its sidewall pressure, and tension along the run.
STEP 12 OF 27The cable in the conduit, to scale: 30 percent fill.
STEP 13 OF 27How it was worked out: 279 lb, 306 lb/ft, a 1,500 lb class puller.
STEP 14 OF 27The inputs these figures used.
STEP 15 OF 27The run, step by step, in the order the cable meets it.
STEP 16 OF 27The findings: tension, sidewall and jamming all OK.
STEP 17 OF 27The other way: 328 lb and 349 lb/ft. This way is easier.
STEP 18 OF 27The same pull in a different pipe: every size, standard 90 and large sweep.
STEP 19 OF 27The pulling attachment: a basket grip is within the published limits.
STEP 20 OF 27Pulling equipment: a 1,500 lb class puller, sized to its continuous rating.
STEP 21 OF 27Lubricant: Polywater J, 0.56 gallons, and how that was worked out.
STEP 22 OF 27The choices behind this plan.
STEP 23 OF 27The full analysis, line by line.
STEP 24 OF 27How every number was reached: each equation with this pull's figures.
STEP 25 OF 27The pull plan: save or share the PDF, or save the job.
STEP 26 OF 27What is jamming? The app's own explanation, opened.
STEP 27 OF 27The PDF, page 1: the plan for the crew.
The same 27 screens with the captions burned in. No sound.
MP4, 3.0 MB, 28 seconds.
The pull plan PDF for the same job, all 15 pages as the app writes it: the plan on pages 1 to 9, then the Southwire cable sheet (pages 10 to 13) and the Wheatland elbow sheet (pages 14 and 15) it was worked from, attached unaltered.

Where pull tension was first built, inside the estimate, so the answer can change what you bid. The 3D run entry, the vertical-bend equations and the drawings on this page came out of the app and are being brought back across.
