Home, car, and pet upkeep — finally in one app, for one price! (pay either monthly or yearly for a discount) Most reminder apps just do calendars. TASKinterval does maintenance intervals: it knows an HVAC filter is due every 90 days, an oil change every 5,000 miles, and a flea treatment every month — then tells you the moment each one comes due, so small upkeep never turns into an expensive repair. All intervals are customizable to your needs! One App For Everything You Maintain • Home — HVAC and furnace filters, gutters, appliances, water filters, seasonal tasks • Car — oil changes, tire rotations, registration — tracked by date OR by odometer mileage • Pet — vet checkups, vaccines, flea & tick, heartworm, grooming Date And Mileage Intervals Track "every 6 months" and "every 5,000 miles" side by side. Enter your odometer and TASKinterval works out when a mileage-based task is coming due — something a plain calendar can't do. Don't want manual entry for your odometer? Just take a picture of it instead to save you time! Set Up In Seconds With AI Describe your home and vehicles in a sentence ("3-bed house, gas furnace, a 2015 Honda Civic") and TASKinterval drafts a starter maintenance plan you can review, edit, and keep. Not sure what you're missing? Ask "What am I forgetting?" and get suggestions based on what you actually own. Ask Your Maintenance Advisor Wondering "How often should I clean my gutters?" or "My car shakes at 60mph — what should I check?" TASKinterval's built-in AI advisor answers with practical guidance based on the home, vehicles, and pets you actually track — and when it suggests a task, you review it and add it to your schedule in a tap. Reminders That Actually Help • A notification the day something's due — tap to mark it done • A home-screen widget showing what's due soon at a glance • Gentle streaks and badges for keeping up • See an estimate of the repair costs you could avoid by staying on schedule Honest And Private • No ads. No upsells. We don't sell your data. • Anonymous analytics only — your task list stays yours. TASKinterval: Start with a 14-day free trial, then $4.99/month or $39.99/year for full access: AI setup, the maintenance advisor, and date- and mileage-based reminders across home, car, and pet needs! TASKinterval is an auto-renewing subscription. The 14-day free trial automatically converts to a paid subscription unless cancelled at least 24 hours before it ends.
