A developer's answer to the spreadsheet chaos of managing a few rental properties.
If you own one or two rental properties, you know the drill. Rent is due on the first. Some tenants pay on time, others don't. You track it in a spreadsheet, a notebook, or maybe just in your head.
It works... until it doesn't. You forget who paid last month. You lose track of a partial payment. Tax season arrives and you're digging through bank statements trying to piece together the year.
I looked for an app that could handle this. What I found were property management platforms built for landlords with 50+ units -- complex, expensive, and full of features I'd never use. Nothing for the person with a couple of apartments who just wants to know: did everyone pay this month?
I'm a developer focused on real estate management tools. I built RentDue to solve a specific problem: give small landlords a clear, instant view of their rent status without the overhead of enterprise software.
The app does one thing and does it well. Open it, see which tenants have paid and which haven't. Log a payment in two taps. Export a summary for your accountant at the end of the year. That's it.
Your tenant names, rent amounts, and payment history stay on your device. There's no cloud sync, no account to create, no server storing your data. I chose this on purpose.
Small landlords deal with sensitive financial information. You shouldn't need to trust a startup's server security just to track rent. RentDue works offline, completely. Your data is yours.
RentDue is not trying to be everything for everyone. It's built for independent landlords managing a small number of properties -- the people who don't need tenant portals, maintenance ticket systems, or accounting integrations.
If you have 50 units, this app is not for you. If you have a duplex, a couple of apartments, or a small rental house, RentDue was made with you in mind.
The core of RentDue is free. Track your properties, log payments, see your rent status -- no paywall. Pro unlocks extras like payment reminders, PDF/CSV exports, and support for more properties for landlords who want the full toolkit.
No ads. No data selling. The app sustains itself through Pro subscriptions from landlords who find it useful enough to pay for.
Available on Android and iOS. Set up your first property in under a minute.
