Moving into a new place? Document everything before you unpack. When you move out, the difference between getting your full deposit back and losing hundreds of dollars often comes down to one thing: proof of what the place looked like when you arrived. Vault makes that proof in minutes. Walk through your new apartment and capture each room and item. A quick photo, a timestamp, and a note on its condition. Vault organizes it into a clean record and turns it into a professional PDF or spreadsheet you can keep, email to your landlord, or hold onto for the day you need it. No more scrambling through your camera roll at move-out. No more "it was already like that" arguments with nothing to back you up. WHAT PEOPLE USE VAULT FOR Move-in and move-out records — capture the condition of an apartment, home, or condo, including existing damage like scuffs, stains, and chips Insurance itemization made simple — document your belongings room by room, with photos and estimated values, so a claim doesn't start from memory Proof of ownership and condition — every entry is timestamped at the moment of capture, creating a dated record of what you had and what shape it was in A clean home inventory — everything you own, organized, searchable, and exportable whenever you need it HOW IT WORKS Scan an item's barcode, snap a photo, or enter it by hand Note the condition, and capture any existing damage Group everything by place, so each apartment or home is its own record Export a polished PDF or CSV whenever you need it WHY VAULT Fast.

Verdict
The clearest difference is monetization model: Vault at free against PDF Pro's subscription. Vault also leads on update cadence (every 5 days vs every 2 months) and rating (5.0 vs 4.7). PDF Pro's advantage is ratings volume (7K vs 1). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PDF Pro sells 12 in-app purchases, starting at $1.99 per month and Vault sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Vault holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PDF Pro has 7K ratings behind it against 1, so its average is the more settled of the two.
PDF Pro ships an update every 2 months, Vault every 5 days. The most recent releases landed on November 1, 2026 and October 16, 2026 respectively.
