After months of building in public, RentDera is now live on Google Play.

This post isn't about code. It's about what RentDera is, who it's for, and why I built it.
The notebook problem
Walk into almost any rental building in Nepal and ask the landlord how much rent is due this month. Chances are they'll reach for a notebook.
That notebook holds everything: which tenant lives in which room, who paid last month, who paid only half, what the electricity meter read on the 1st, how much deposit was taken when someone moved in three years ago. It works, until it doesn't:
- A page gets torn, wet, or lost.
- The meter reading was written on a scrap of paper that's gone now.
- A tenant says "I already paid that" and there's no receipt to settle it.
- Adding up who owes what across ten rooms takes an evening with a calculator.
- Nobody remembers whether the advance from Baisakh was already used.
Landlords aren't doing anything wrong. The notebook just isn't the right tool for a job that has quietly become complicated.
What RentDera does
RentDera replaces the notebook with your phone. Here's what a month looks like in the app.
Set up once. Add your building, its rooms or flats, and the tenants living in them, along with their rent and when it's due.
Bills make themselves. Every month, RentDera creates each tenant's bill automatically. Rent is already on it. Enter this month's electricity or water meter reading and the charge is worked out for you. No calculator needed.
Record what you receive. A tenant pays in full? One tap. Pays only part of it? Enter the amount, and RentDera remembers exactly how much is still owed, month after month.
Send a receipt. Share a receipt straight to the tenant over WhatsApp, Viber or any messaging app. No more "I already paid" arguments.
Send a polite reminder. Someone's late? Share a reminder with the amount and month already filled in.
See everything at a glance. The home screen shows what you've collected this month, what's still outstanding, which rooms are empty, and how your income has looked over the past year.
Track money going out, too. Record repairs, painting, utility bills and other costs. RentDera shows a simple monthly statement: money in, money out, and what's left.
Keep deposits and advances straight. Record the deposit you took when a tenant moved in, or money they paid ahead of time. RentDera keeps it separate from your income, because it isn't yours to spend, and lets you put an advance toward a month's bill when you need to.
Bring your old records with you. Already have years of history in a notebook? You can enter past deposits, advances and unpaid amounts so you start from where things actually stand, not from zero.
Made for Nepal first
Most property apps are built for landlords in America or Europe. RentDera started with the way renting actually works here:
- Nepali and English. Switch the language any time.
- Bikram Sambat dates. See billing months in BS, AD, or both.
- Metered utilities. Electricity and water charged by meter reading are built in, not an afterthought.
- Your currency. Track rent in rupees, or whatever currency you use.
- Works the way rent is really paid. Partial payments, cash in hand, payments that round up and leave a little extra — RentDera handles all of it.
It's not only for Nepal. Any landlord who manages a few buildings and is tired of the notebook can use it.
What it costs
Free for one property and five units, with every feature included. No trial that runs out, no card required, no features held back.
If you manage more than that, RentDera Pro removes the limit. That's the only difference between the plans. You can see the prices for your country on the pricing page.
If you ever stop paying, nothing is deleted. Your tenants, bills and receipts stay exactly where they were.
How it was built
RentDera is a one-person project. I built it in public as part of RevenueCat's Shipaton 2026, shipping four updates in September alone and writing up the mistakes along the way. Earlier posts in this series cover the night a missing setting crashed the app, the free-tier limits that took it offline, and a sign-in bug that only appeared after release.
Getting to a public Play Store listing meant weeks of closed testing with real testers, a review that took about a week, and a lot of learning about how app stores handle payments in Nepal. It's been a long road, and it's good to finally say: it's live.
Try it, and tell me what's missing
If you're a landlord, try RentDera with one building and see if it saves you time. If you know a landlord still using a notebook — a parent, a relative, a neighbour — please share it with them.

I read every message. If something is confusing, missing, or just wrong, email me at support@notils.com or leave a comment below. The next version will be shaped by what landlords actually need.
Thank you to everyone who tested the early versions and followed along. This is just the start.

Congrats on the launch, Sanjay! I like that you’ve accounted for everyday details like partial payments and meter readings.
One thing I’m curious about: can a landlord invite a caretaker or property manager with limited access? For example, someone who manages tenant details, meter readings and day-to-day property work, while payment records stay under the landlord’s control. Does RentDera support this, or is it something you’re considering?
