Stop forgetting. Start maintaining. Owning a home means a hundred small things quietly need doing — and nobody hands you the list. Maintnr keeps track of all of it, so you don't have to keep it in your head. No more lying awake wondering when you last flushed the water heater. No more sticky notes. No more "I think I changed that filter… last year? Maybe?" Whether you just got the keys, you've owned the place for decades, or you're managing a portfolio of rentals, Maintnr turns "I really should keep up with this" into a routine that actually sticks. EVERY TASK, EVERY COST — UNLIMITED, FREE Log what you've done, track what you spent, and see your year-to-date costs at a glance. Add as many tasks as you want on the free plan — no caps. When it's time to budget (or sell), you'll finally know where the money actually went. BUILT AROUND YOUR HOME Tell Maintnr about your home during setup — your systems, outdoor spaces, what matters to you — and it builds a task list tuned to your actual house & your actual climate. Recommendations factor in your home's features and area, so you get spring, summer, fall, and winter tasks that make sense where you live. No reminders to winterize a pool you don't have. DIAGNOSE A PROBLEM (PRO & PRO PLUS) Something leaking, humming, or just not right? Describe it and Maintnr gives you the likely causes, how to fix it, and a ballpark on what it should cost — before you call anyone or panic-search at midnight. BUILD A RESALE HISTORY THAT PAYS YOU BACK (PRO) Think of it as a Carfax for your home. Every task you log builds a documented maintenance history — and when it's time to sell, export a clean report covering any date range. Most sellers can't prove a thing. You'll hand over the receipts. BE READY BEFORE YOU NEED TO BE (PRO) Generate an insurance-ready report documenting your maintenance history and your rooms — exactly what adjusters want to see — so the worst day is a little less awful. FOR LANDLORDS AND PORTFOLIO OWNERS (PRO PLUS) Unlimited properties, capital improvement and depreciation tracking, tenant records, and Schedule E expense reports you can export at tax time. Stop rebuilding the same spreadsheet every January. (Maintnr helps you organize records — it isn't tax advice.) SHARE ACCESS WITH YOUR PARTNER Invite a spouse, partner, or assistant into your account so you're both looking at the same list. No more forwarding screenshots to prove the gutters got done. KNOW WHAT YOU OWN Catalog your appliances and home assets — add and edit your full inventory, free. Track purchase dates & warranty expiration. Get alerted before coverage lapses, so a dead dishwasher in month 13 doesn't quietly become your problem. YOUR PEOPLE, ONE TAP AWAY Store your go-to plumber, HVAC tech, and electrician right in the app. When something breaks at the worst possible moment, you're not digging through old texts for a number. PLANS, PLAINLY Free covers unlimited task tracking and inventory for a single property — genuinely useful on its own. Pro adds: • Diagnose a Problem — AI-powered cause, fix & cost guidance • Resale Report with configurable date range • Insurance Report for claims documentation • Warranty tracking & expiration alerts • Cost tracking & year-to-date summaries • Up to 5 properties Available monthly, annually, both with a free 1-week trial. Pro Plus adds: • Unlimited properties • Depreciation & capital improvement tracking • Schedule E expense data and exports • Tenant records Available monthly or annually. DARK MODE Because you're probably checking this at 10pm, in bed, having just remembered something you were supposed to do in the attic. Built by an independent developer who also owns a house and also forgets to change filters. We get it.
