Why people choose RashScan over First Derm

About 60 seconds from photo to report.
Free to try. Scanning with RashScan costs nothing; you only pay if you want the full report. First Derm's AI tool costs $11.99 before you see a result.
Far cheaper. A RashScan full report costs less than half of First Derm's cheapest dermatologist reply.
A complete rash report. Not just a name: the most likely condition with a confidence score, how serious it looks, a treatment plan, how long it usually takes to heal, and the warning signs that mean you should see a doctor.
It asks what a doctor would ask. Itch, pain, fever, how fast it is spreading, when it started, new products or triggers. Two rashes can look alike in a photo and still be very different things.
