Description by Phuc Pham(from the App Store)
Set every ladder at the safe angle before you climb. LadderAngle finds the correct 4:1 lean (about 75.5°) from your wall height and ladder length, then lets you check the real angle live with your phone.
Most ladder falls come from one thing: the wrong angle. Too steep and it tips back, too shallow and the feet slide out. LadderAngle turns the OSHA / HSE 1-in-4 rule into a two-second check — do the math first, then lean your phone on the rail and watch the on-screen angle turn green when it's right.
WHAT YOU GET - The exact safe angle and base distance for your ladder, in metric or imperial - A clear SAFE / CAUTION / UNSAFE verdict as you type, so you never guess - A live inclinometer that reads the real ladder angle and locks the reading - A visual ladder diagram that updates as you change height, base or length - Saved setups for every ladder and job you check regularly - A built-in safe-setup checklist, 3-points-of-contact and duty-rating reference
PERFECT FOR - Roofers and gutter cleaners setting extension ladders - Painters and decorators working off a lean-to ladder - Trade and construction crews who need an OSHA / HSE angle check - Home DIYers who want to climb without taking a chance
WHY NOT JUST EYEBALL IT Guessing is exactly how ladders slide out. The 4:1 rule looks simple, but the base distance changes with every wall height — LadderAngle does that math instantly and then proves it against the real angle with your phone's motion sensor. No tape measure, no protractor, no maths in your head.
