      Software Development Review from Lori Feld Oakley

      Our Services organization is scaling quickly and we urgently needed a custom software application to automate our workflows, without breaking our annual budget. CodeStringers was the perfect fit, supporting us from ideation through go-live and everything in between. They innovated, hit their deadlines and released an amazingly high quality application that decreases our internal costs and improves our reputation with our customers. It would not have happened without CodeStringers.

      Enterprise Review from Christian Schraga

      CodeStringers is the perfect outsourcer to call If you have a solid software business idea but don’t know exactly how to bring it to life. They have both a top-notch development team as well as an executive staff with expertise in marketing, finance, and general business acumen. So they can not only build a product for you but they can make sure that the product you want to build is likely to succeed in the marketplace.

      From my initial consultation to the completion of the development process, the entire team at AppStem has been a pleasure to work with. With so many Mobile App Development companies to choose from, it's important to chose one who is willing to understand your needs and clearly outline a game plan before getting into development. If you're looking for more of a partner than just an agency, you're in good hands with AppStem.

      I agree with the other review. This company claims that they can build websites and that they are located in Modesto, California which is not true. I have been calling them for weeks and so far no response. When I told them that I wanted a refund, they quiclky put some items on the website. They are very dishonest
