ScienceSoft has worked with us to develop a library application for Windows, macOS, iOS, and Android. They suggested and implemented a multi-platform framework that minimized development costs. We have continued iterating on that application and adding new features over several years, and ScienceSoft's developers have been great at implementing the designs that we give them, as well as suggesting ideas themselves. They produce good code, they are quick to respond, detail-oriented, and a very good value for our money.
