One of the best features of Roomi is that it keeps safety in mind during every step of your search: users can ask potential roommates to complete a background check before they even apply to their listing, and they can send messages via the app without giving out their personal email. But Roomi is also a solid option simply because it's available in dozens of cities all over the US and Latin America, and it boasts over 500,000 installs on the Google Store.
In the words of one happy customer: "We used Craigslist before for new roommate searches, but heard good things about Roomi. The quality of people were a mixed bag, but overall we had several good candidates and picked one that came from Roomi."
