Southern Oregon Contractor Services
I have been using this app for 7+ years now. It has been very useful!
Can’t cancel
There’s no way to cancel your subscription within the app. If there is it’s not obvious and the developer is not responsive to requests for help.
Too limited
I had to fit steps between a preexisting loft and a preexisting landing space and needed to know the rise and run by backing into those numbers. This app couldn’t help.

No me sirve
Cancelled after poor numbers that didn’t add up
Cancelled after numbers made no sense
Kinda helps
Was looking for something that would calculate the total run based on height. Have to enter the total run which is what I needed to know. If you have run/rise then it gives options for number of stairs.
Really helpful
Gave me the information that I needed. Slow down on the flipping of the device maybe…a close shot of The end cuts. Just thoughts.. mine worked out. Thank you.
I’m not a fan of the idea that you make your app look like a learning tool, actually it’s bloatware.
I am very experienced in takeoffs and Iso’s from many different companies and -regions , so I would like to be clear about the best approach for this project, disclose your contractual terms prior to download. If the app doesn’t provide uninstall option then I can add one for you.
Doesn’t work for me
Just didn’t work for me I’m canceling
Why pay money when you can get it for free?
I downloaded the app with a free trial period and there appears to be no way to cancel it so that you will not be charged.
Excelente
Fácil de operar y datos precios
Obnoxious ads
The ads are obnoxious. And have nothing to do with construction.
Clunky, more features needed
Full pic incl floor level and landing level with joist height. Stringers do not float in air.
Fraud
Attempted to discontinue trial but there is no option to do so. Also tried to contact them to cancel and no response. They make you opt into a trial but dont give you option to cancel and just take your money.
Stair Calc
Very easy to use
Horrible
OMG this is a horrible app. Give me a break.
Easy to immediately understand and use
If your need is to calculate your rise, run and stringer specs, this is perfect. Pros: 1) interface is visually clean 2) obvious how to input and calculate 3) output gives variety of options 4) quickly run various scenarios 5) No in app ads! 6) Free! Cons: 1) Apparently the developer won’t actually come to the job site and cut the stringers for me. 😀 My project is to replace two precarious staircases in a home built in 1923. For a remodeling situation where we are dealing with several variables and wanting to try “what if’s?” this is perfect. Thank you Dang Phan!
Scam
Total scam does not provide any information just transfer you to another app to buy.
