It's an app that makes storing and finding things easy - things that you don't use often, but that can come in handy at any moment.
For example: tools, seasonal clothes, various accessories, spare parts, household items, etc.
We often "misplace" such things because we don't remember where we put them or who we gave them to. The search for these things can take a long time, and sometimes we just buy the new ones.
Stuff Keeper not only helps you find and store your stuff - it also saves your money!
Pack your things in your phone and don't misplace them anymore.
App also makes life easier for people with various memory disorders, information overload, ADHD, etc.
