# OnOtto

> OnOtto (www.onotto.com) is a home maintenance app that puts your home on autopilot: recurring tasks that persist until they're actually done (completing one schedules the next), photo-based appliance identification that builds each appliance's maintenance schedule automatically, AI inspection-report import, and household sharing for up to 6 people with weekly streaks. OnOtto keeps "I'll do it tomorrow" from turning into "oh no, I should have done this last year."

Key facts:
- Pricing: Free plan (15 tasks, 2 members, 1 AI scan) · Solo $4.99/mo or $39.99/yr · Family $8.99/mo or $71.99/yr (up to 6 members) · Founder Lifetime $199 once (first 500 households). 30-day full-access trial, no credit card.
- Headline feature: snap a photo of an appliance and OnOtto identifies it, builds its maintenance schedule, and asks when you last did each task. No manual required (manual/PDF upload and inspection-report import also supported).
- Company: founded 2020, relaunched 2026, based in Washington State, USA. Contact: hello@onotto.com. App: https://app.onotto.com
- The problem it solves: the average US homeowner loses about $3,000/year to preventable repairs, mostly because calendar reminders get snoozed and dismissed.
