About this app

Rental Book keeps your rooms, tenants, rent and electricity bills in one book on your phone. It is made for landlords, PG owners and families who let a few rooms, and it works in English, Tamil and Hindi.

START FROM YOUR NOTEBOOK
• Photograph the pages of your rent notebook: the rooms, tenants, rents and advances are read off them. You check every line before anything is added.
• Or fill in one Excel sheet with all your tenants at once.

RENT AND DUES
• Rent is charged every month on its own.
• See at a glance who has paid, who owes, and how much.
• Record a payment in two taps — cash, UPI or bank — even with no signal.
• Advances, rent revisions and move-outs are worked out for you.

EB AND WATER BILLS
• Enter what the board charged and split it between the rooms on a meter.
• Or bill each room from its own sub-meter reading.

TENANTS AND THEIR PAPERS
• Each tenant's details, ID and address proof, rental agreement and police verification form in one place.
• ID numbers are stored encrypted, and only the last four digits are shown.

RECEIPTS AND HRA
• A rent receipt for every payment, ready to share on WhatsApp.
• A year's HRA statement for a tenant who works.

REMINDERS
• Send a tenant what they owe from your own WhatsApp in one tap, with your UPI ID so they can pay you straight away.

EMPTY ROOMS
• A To-Let poster for the gate, with the rent, your number and a QR code to the room's photos.
• Share the room's page on WhatsApp. Once somebody moves in, it says the room is let.

UPI STICKERS FOR THE DOORS
• Print a UPI QR sticker for each room. A tenant scans it with any UPI app and the money comes straight to you, with the room written in the payment.

REPAIRS AND ROOM PHOTOS
• Tenants tell you what needs fixing from their pay link, with a photo if they like.
• Photograph each room when a tenant moves in and again when they leave, side by side, and take damage from the advance with the photos as proof.

IN THE TENANT'S OWN LANGUAGE
• Tenants read their form, receipts and pay page in Tamil, English, Hindi, Telugu, Kannada or Malayalam.

WORKS WITHOUT SIGNAL
• Payments and bills entered with no signal are kept on the phone and saved as soon as the connection is back.

FOR THE WHOLE FAMILY
• Owners, managers and viewers share one book, each in their own language.
• Bigger text in Settings, for easier reading.

Free to start. Your data stays yours: download it as spreadsheets at any time, or delete your account from Settings.
