How to make an app for a rental property owner

An owner with a few flats and shops has to remember a lot: who pays on the 1st and who on the 10th, which agreement ends in March, how much deposit each tenant gave, what the plumber cost last month. An app on your phone keeps every property's rent, deposit, dates and repairs in one place, so the year-end total is ready too.

Who uses the app

Just you, or you and a family member. On one phone, the data stays on it and works offline. If a family member also collects rent, or a caretaker logs repairs, connect your own Supabase database so you both see the same records.

The screens a rental property owner app needs

Properties: Each flat, shop or office with address, size and whether it is let or vacant
Tenants: Tenant name, phone, family or business, ID type noted, move-in date and police verification done or not
Rent: This month's rent for each property, paid, part-paid or due, with the date paid and mode
Deposits: Deposit taken, date, any deductions and the amount returned at move-out
Agreements: Start date, end date, the rent increase you agreed and when renewal is due
Repairs and expenses: Plumbing, painting, property tax and society charges for each property
Year summary: Rent received and expenses by property for the year, ready to give your CA

Features worth asking for

A rent reminder on WhatsApp with the tenant's name, month and amount filled in
A reminder on your phone 60 days before an agreement ends
The yearly rent increase worked out from the rate you agreed
A rent receipt as a PDF to share with the tenant
Photos of the flat attached at move-in and move-out
Income and expenses per property for the year
A list of vacant properties with the date each fell vacant

Where the data lives

If only you use the app, the data stays on your phone and works offline. If a family member or caretaker uses it too, connect your own Supabase database. To let tenants pay rent in the app, connect your Razorpay account as well.

How to make it with AppCub, step by step

Decide what the app does. List the screens you need, for example: Properties, Tenants, Rent, Deposits, Agreements.
Describe it to AppCub. Paste the request below, changed to your own business and details.
Check the plan. AppCub shows the screens and features it will build. Change them in the chat until they are right; seeing the plan is free.
Try it on your phone. The app runs live next to the chat. Scan the QR code to install it, and ask for changes.
Share it. Share it as a web link, an APK file, or publish it on Google Play from your own developer account.

Copy this request, change the details to match your rental property owner, and paste it into AppCub:

Make an app for my rental properties in Delhi: three flats and two shops. Screens: properties, tenants, rent, deposits, agreements, repairs and expenses, and year summary. Each tenant has phone, move-in date, ID type and whether police verification is done. Rent is due on different dates; show paid and due with a WhatsApp reminder and a PDF receipt. Agreements have start and end dates and a yearly increase; remind me 60 days before an agreement ends. Track deposits and deductions. Show rent and expenses per property for the year. White and teal.

Tips for a rental property owner app

Start with properties, tenants and rent. Add agreement dates and expenses from your files over the next week.
Attach move-in photos of each flat; they help when you settle the deposit later.
The app only records dates and amounts you enter. For what your rent agreement should say, ask a lawyer.
Many owners get tenant verification done with the local police; the app can note whether it is done, but check your area's process yourself.
Give the year summary to your CA as it is; ask them what else they need, rather than guessing tax rules.

Good to know

AppCub doesn't connect to banks or accounting software and doesn't send reminders to tenants by itself; you tap the WhatsApp button. It doesn't draft or check rent agreements or give legal or tax advice.
AppCub builds Android apps. You can also share the app as a web link that opens on any phone; for the iPhone App Store, AppCub’s team can do it for you.

Questions

Can the app remind me when a rent agreement is ending?

Yes. In the installed Android app, a reminder shows on your phone on the date you choose, such as 60 days before the agreement ends.

Can tenants pay rent through the app?

Yes, through your own Razorpay account once Razorpay and Supabase are connected. A simpler start is your UPI QR code with a 'Pay via UPI' button.

Can the app make my rent agreement?

No. The app keeps the agreement's dates and terms you enter and reminds you of them. For the agreement itself, use a lawyer or the process in your state.

Can I see the income from each flat for the year?

Yes. The year summary shows rent received and expenses for each property, which you can share with your CA as a PDF.

Can I keep a scan of the agreement in the app?

You can attach photos of the signed pages to a tenant. Keep the original paper copy safe as well.

Is it worth making an app for only three or four properties?

Often yes. Rent dates, deposits and agreement renewals are easy to lose track of, even with a few tenants.
