★★★★★ A Google User · May 14, 2013
Thanks for making it free The way it shows explanation is good, and I never saw a perfect app like this in the market. Please make all possible tools for Operation Research (Transportation and Assignment models, Integer programming Models, Scheduling PERT & COM, Queuing Model).
★★★★★ A Google User · Apr 2, 2014
Simple and efficient That's exactly what I needed for operational research and linear programming.
★★★★★ A Google User · Apr 9, 2014
Very Awesome !!! This app is unbelievable... I'm using it in all courses of Operational Research that I teach. All of my students really love it.
★★★★★ Insertx2k Dev · Dec 28, 2025
Better than ChatGPT in solving Simplex Problems, and gives a better detailed step-by-step guide that's helpful in case I missed a step. I Definitely recommend!
