Step 1
You set it up in minutes
Add your garment measurements per size, right in the dashboard. No code. This is what makes DerFit different — recommendations come from your real product measurements, not a one-size-fits-all chart.
Step 2
Your customer scans their body
On the product page, your customer takes 4 quick photos in their browser — no app download. DerFit reads their actual body measurements, instead of guessing from height, weight and age like most tools.
Step 3
They get their perfect size
Your customer sees their recommended size and their measurements, and buys with confidence. You get fewer wrong sizes, happier customers who come back, and real data on how your products actually fit.
That's the difference: a real scan, not another size chart.
