Had i not used this app i would’ve fallen over in shock when i looked into my bedroom window. ### 3/5 — Measure tool of this App is no longer working *2022-07-25* Recently downloaded this app again, the most recent update seems to have rendered the measuring angle aspect of this app inoperable. Please fix this when you get a moment! ### 5/5 — Great training tool *2022-03-28* I use this with my employees when I inspect job sites. Thanks!!! ### 3/5 — Why IOS 13? *2021-09-28* It only uses and inclinometer, this makes it unusable on older devices (iphone 6 and older). Good idea but doesnt need to be compiled for ios13 … ### 2/5 — App want open *2021-08-24* This was a great app. However the app will not open now. The developer forgot to update its version so that it is compatible with the latest iOS ### 1/5 — My neighbor Rick recommended this... *2020-03-15* This is good to have on your phone at the work site to show the boss man you don’t need his “input” on ladder safety. At home, I pretend to need Rick’s help with the interface, and while he’s explaining it to me, I make sideways glances at his wife. Win-win. I don’t know if the app is any good, but I make my own rules...ladder safety included. ### 1/5 — My ladder, my rules *2020-03-15* Don’t try to tell me what I can’t do with my own ladder. Too shallow, too steep, unless you’re at “perfect” angle it makes a horrible noise you try holding this thing up against the side of the ladder when you’re 40ft up in the air and try to readjust your angle and you’re going to have a bad accident anyway. Better to just go with your gut. ### 5/5 — Great App! A must have!!! *2018-09-22* Thank you for developing this most useful App...a must for all! ### 5/5 — E&S Director *2015-11-04* 85 mb is well worth the safety of all employees. All safety individuals will value this app. ### 1/5 — 85MB?! *2015-06-29* Way too large of an app for a utility. Get it down to a reasonable size like 1MB and then we'll use it ## Frequently asked questions about Ladder Safety ### How does Ladder Safety help determine the correct ladder angle?
