AptBook
The $1,700 apartment costs $2,110 — AptBook does that math
Log every unit you tour, add the fees the leasing office quotes, and get one honest monthly number per unit: mandatory fees added, one-time charges and move-in specials spread across the lease. Then rank your finalists. Free, no account.

What you can do in AptBook on the web
Sixty-second tour capture
Nickname, source, quoted rent, deposit, lease term, beds, baths, square feet and the move-in special — with the true monthly number updating as you type.
True-monthly-cost engine
Advertised rent + mandatory monthly fees + one-time charges ÷ lease term − the move-in special ÷ lease term, with a delta badge against the advertised rent.
Ten-point tour checklist
Cell signal, water pressure, noise, outlets, light, laundry, storage, smell, parking and commute — answered fine, flagged or unchecked, each with a note.
Weighted compare board
Finalists ranked 0–100 on a weighted blend of cost, location, condition and amenities, with true monthly, price per square foot and flag counts side by side.
Application fee ledger
Every $30–$75 application and admin charge with its building, date and status, plus a running total and fees-per-week chart so the cost of the search stays visible.
Shareable comparison sheet
Copy the ranked sheet as text or download it as CSV to send to a partner or co-signer before anyone signs.

Questions
Is the web version of AptBook free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the AptBook iPhone app?+
No tour photos filed by room — the iPhone app stores images per unit; the web version keeps the numbers, checklist answers and notes. The comparison sheet copies as text or downloads as CSV rather than rendering the iPhone app's one-page PDF. Everything lives in this browser only, so a hunt started on your laptop will not appear on your phone.
