Why does OOS make free apps?
Helping small shops go digital
Many service shops still keep paper records because management software is often complex and costly. We want them to have simple tools they can use right away.
Real products, real users
Running products every day teaches the OOS team what software needs to stay in use: speed, clarity and reliability.
A look at how we work
Before you commission a project, you can try OOS products yourself and judge the quality of design and finish.
We will keep adding new apps to this page.
Need software built for your business?
If an existing application does not fit your process, OOS can build software to order, the same way: simple for users, solid underneath.
