Specialist slots open every day when patients cancel. They fill within minutes — not because you were too slow, but because no one was watching for you. Until now.
Dermatology, orthopedics, cardiology — the first available appointment for new patients is routinely months away, even when you need care now.
Every day, slots open when patients cancel. They're filled by whoever happens to refresh ZocDoc at the right moment. That's not a system — it's a lottery.
ZocDoc alerts notify thousands. You still lose. There's no service that actually books FOR you the moment a slot opens. There wasn't, anyway.

"I was quoted a 4-month wait for dermatology. Built SlotFirst to solve that. It found me a cancellation slot 11 days after I set it up — same practice, same doctor."
"Got a cardiology appointment in 3 weeks instead of the 4-month wait they quoted me at the front desk. Got the SMS on a Tuesday afternoon while I was at work."
"Honestly forgot I had signed up. Then I got the SMS — 'Dr. Chen, Tuesday June 3, 9 AM — booked. Cancel free: [link].' I'm in. That's it. That's the whole experience."
