Simple apps that solve real classroom, gym, and game-night problems.
Rhine-o Enterprises LLC has been building straightforward, useful apps since 2010 — starting with a way to pick teams without a hat full of paper scraps, and growing from there. Family owned and operated, built for teachers, coaches, and anyone who needs a fair, fast way to organize a group.
