Why Crashmates

Mt San Antonio students deserve better.

Other roommate apps don’t verify students. Roomster charges every Mt San Antonio student a subscription to message profiles — most of which are bots or scammers operating outside the US. Bunky doesn’t verify .edu emails at all and doesn’t carry housing listings. Facebook Mt San Antonio groups are full of brokers and fake posts. Craigslist is a privacy nightmare. Crashmates was built specifically for the Mt San Antonio community: only students with a verified @mtsac.edu email can join, browsing and matching are free forever, and you only pay credits when you choose to send the first message — no subscriptions, no auto-renewals, no $30/month surprises. Mt San Antonio students looking for verified students near me, Walnut roommates near me, or Mt San Antonio housing near campus get the cleanest signal of any roommate app on the market.
