Customer Reviews

The D.I.Y.

This is a great app. As a Do It YourSelf'er It was always a hit or miss on material needed which in turn affected coast in spending more than anticipated or spending more than I had to not to mention storage space for the types of material that could not be returned. Well now that I have this app, I get pretty darn close every time, it does have so more than I will ever use but I'm sure if I had the knowledge and experience of a contractor and owned my own business I could use this app to its full potential, but I don't mind one bit paying for some thing that saves me time and money for the projects that I can tackle.. You know what they say better to have it and not need it, than to need it and not have it.!!

Kudos to Updates!

More app developers should be as conscientious as this one. It is good to see a developer working so hard at updating the app they have designed. This program becomes more and more useful longer do you have it. I have owned it for two years.
In my opinion, and app is like an investment. Not only do you want something that works for you. You also want something that adds more value over time. Double dog studios has caught on to this. It will make me a more loyal customer and also persuade me to seriously contemplate any other apps they might release. Keep it up Double Dog!!


I was very excited by reading the reviews, I thought this was gonna be great. Boy was I wrong! It has lots of things and almost all of them are useless. I am a general contractor and every time I tried to use the app I waisted so much time and ended up tossing the phone in the truck and doing it the easy way, the normal way. Gosh I wish someone would come up with a great product for this line of work. One that actually works. I wouldn't mind paying 50 bucks for it, if it actually works. It may work for you, but for me... nuh!
