Speak room by room. Notes write themselves. Export a PDF when you're done. Built for independent landlords, property managers, and appraisers who need move-in, move-out, and condition walkthroughs — not $90/month inspector software. HOW IT WORKS • Pick a template (Move-In, Move-Out, or Appraisal) and enter the property address • Walk room by room through a focused checklist grid — one room expanded at a time • Customize the room list for each property: add, remove, or reorder rooms as needed • Tap a cell to record a voice note or attach photos • On-device speech converts your words into notes automatically • Tap again to replay the exact audio you recorded — proof for deposits and disputes • Export a client-ready PDF with room notes and photos when you're finished WHY UNITPROOF • Voice-first — speak naturally instead of typing on a phone in every room • Audio proof per cell — replay what you said, when you need it • Flexible room lists — start with a sensible default, then add a garage, half-bath, or custom room name • Structured by room — walls, flooring, fixtures, and more, organized for you • Photos attached to the right cell — not lost in a camera roll • Cleaner PDFs — rooms you never documented are left out of the exported report • Works offline — capture stays on your iPhone; no cloud account required • PDF export — share a polished report with tenants, owners, or clients TEMPLATES INCLUDED • Move-In — document condition at tenant move-in • Move-Out — document condition at tenant move-out • Appraisal — room-by-room property condition PRIVACY Your inspections, photos, voice notes, and addresses stay on your device. UnitProof does not upload your walkthrough content to our servers. SUBSCRIPTION Creating inspections is free. Exporting PDF reports requires a Premium subscription or a one-time report purchase.
