What Proof is
Contractors, mechanics, and service companies don't publish their prices, so it's hard to tell a fair quote from an inflated one. Proof gives you a reference point. Send it a quote and it estimates what the work typically costs — adjusted for your location — and points out the line items that look high or vague.
It's the same idea as getting a second opinion, without the second appointment.

Your first check is free. Proof Unlimited is $3.99 / month for unlimited checks, billed through your App Store or Google Play account. Cancel anytime — access runs to the end of the period you've paid for.
Good to know
Proof gives general, informational estimates — it is not an appraisal, and not professional, legal, or financial advice. Real prices vary with parts, materials, condition, complexity, and how urgent the job is.
Use it as a starting point and a set of better questions, then use your own judgment and a licensed professional where it matters.
