It looked like it could be a good app, but very disappointed with how it took over my phone, changed the look and layout of my widgets, would not let me access the app until I installed their calculator then deluded me with sticky add I couldn't use. Acted more like malware than an app. Never had one like it. I'd say it's just a "free" platform for their profit. I dumped it quick. It still has control of my app widget look. 😡

Really great app. It was about 20 years since I last made a set of stairs and this app took out all the guesswork and they came out perfect. I would like to see an option to use different units and/or give useful fractions (8ths, 16ths, etc.) instead of decimals. Update: I found the options after a response to my review. Thanks for your reply. I would give more stars if possible. Absolutely great app.

Thank you for providing your valuable feedback. All the options you need they are already in the app, if you go on settings you can change units to inches with fractions, and after that, near "Calculate" button it is a small button where you can change fraction precision to 8ths, 16ths, etc. If you can't find it please email me.

This is a cool app except that the dimensions on the drawing that the app calls "stringer length view" are nearly useless. The information provided is correct, however, it is very hard to use it in a practical sense. All of the dimensions are relative to each other vs. from a datum point. Using a common point for dimensions is the correct way to dimension a drawing and gives the user a starting place. If it was dimensioned correctly, I'd give it 5 stars.
