UnitKeeper

UnitKeep is the simple property management app built for small landlords — not large companies. If you self-manage 1 to 20 rental units using notes, spreadsheets, text messages, and memory, UnitKeep replaces all of that with one calm, organized app. WHAT IT DOES UnitKeep acts as a property memory system for your rentals. It helps you answer the five questions every landlord deals with: — Who owes what? — What's broken? — What happened in that unit last time? — What's due or expiring soon? — Where's that photo or note? PROPERTIES & UNITS Add your properties and organize them by unit. Track occupancy, rent amounts, lease dates, and notes for every unit you manage. Attach photos of each property for quick reference. TENANT PROFILES Store tenant contact info, move-in dates, rent amounts, and notes in one place. Capture a photo of tenant ID for your records. See which unit each tenant is assigned to at a glance. MAINTENANCE TRACKING Log maintenance issues with priority levels, status tracking, cost estimates, and photos. Snap a picture of the problem, assign it to a unit, and track it from open to complete. Filter issues by status to see what still needs attention. RENT & EXPENSE TRACKING Record rent payments (full, partial, or late) and log expenses by category. See monthly totals for what you collected versus what you spent. Photograph receipts and invoices so nothing gets lost. CONTACTS DIRECTORY Keep a directory of your plumbers, electricians, HVAC techs, contractors, realtors, attorneys, and other contacts organized by type. Tap to call or email directly from the app. PHOTO EVERYTHING Use your camera to photograph properties, tenant IDs, maintenance issues, damage, and receipts. Every photo is attached to the relevant record so you can find it when you need it. MAKE IT YOURS Choose your preferred color theme and accent color. Switch between light, dark, or system appearance. DESIGNED FOR SMALL LANDLORDS UnitKeep is intentionally simple. No bloated dashboards. No enterprise features you'll never use. No complicated setup. Just open the app, add your property, and start keeping track. Your data stays on your device. No account required. No cloud dependency for the basics. FREE & PRO The free version includes full functionality for up to 2 properties — no feature restrictions, no time limits. Upgrade to UnitKeep Pro with a one-time purchase of $6.99 to manage unlimited properties. No subscription. Pay once, keep it forever. Whether you have a duplex, a few rental houses, or a small apartment building, UnitKeep helps you stay organized without the overhead of software designed for property management companies. UnitKeep. The landlord app that finally makes the small stuff manageable.
