KeyProof is the walkthrough app for renters and buyers. Room by room, capture photos, video, and voice notes. Get a timestamped PDF the other side can't dispute.
Four steps. Under an hour. A PDF you can put on the closing table or in your landlord's inbox.
Type the address or paste a Zillow link. KeyProof auto-fills price, beds, baths.
Snap photos, record short videos, add voice notes. Flag pre-existing damage with a tap.
Timestamped, geo-tagged, formatted like a real inspection report. One tap.
Email to your landlord or take it to closing. Get it counter-signed and file it forever.
Whether you're moving in or closing on the biggest purchase of your life — KeyProof adapts.
Document the place on move-in day. Send the PDF to your landlord within the first week. Show it again at move-out — every flag is dated and undisputable.
Walk through 24-48h before closing. Catch incomplete repairs, new damage, or missing appliances. Take the PDF to the table to negotiate credits.
The full walkthrough kit — everything renters and buyers say they wish they had.
Capture however suits the moment. Voice notes get transcribed into the PDF automatically.
8 rooms preloaded. Fully editable. Progress bar so you don't miss anything.
Address as the headline. Sober legal preface. Signature blocks. Formatted like real inspection reports.
Tap once to flag pre-existing damage. Compiled into a dedicated summary page at the end.
Paste any listing link — KeyProof pulls the hero photo, price, beds, baths.
Photos never upload. Your walkthroughs stay on your iPhone unless you choose to share.
