OneHaus vs Cozi (2026) | Best Cozi Alternative
Cozi is a solid free family calendar and list app that's been around for years. OneHaus goes further with AI assistance, home inventory tracking, task rotation, and a modern interface. If you've outgrown Cozi's basics, OneHaus fills the gaps.
What is Cozi?
Cozi is a free family organiser that has been available for over 20 years. It's one of the most established apps in this space, with a large and loyal user base built on the strength of its simplicity and reliability.
Its core features are a shared colour-coded calendar, shopping lists, and to-do lists. The calendar is its strongest offering. Each family member gets a colour, and appointments are visible to everyone in the household. Shopping lists sync in real time across devices. To-do lists allow basic task assignment to household members.
The free tier is useful but has limitations. Since 2024, free accounts can only view 30 days of calendar events, which restricts planning ahead. Cozi Gold, priced at around $40 per year, removes the adverts, lifts the calendar restriction, and adds extras like mobile month view, multiple reminders per event, and SmartAdd for natural language event entry. A newer tier, Cozi Max at around $60 per year, adds AI-powered features including event import from emails and photos, an AI recipe creator, and an AI meal planner. Recipe management and the family journal are available on the free tier. The app is available on iOS, Android, and web, which gives it broader platform reach than many competitors.
What is OneHaus?
OneHaus is an AI-powered household management app built for households that need more than a shared calendar and a couple of lists. It brings tasks, a shared calendar, shopping lists with automatic aisle sorting, home inventory, and an AI assistant into one app.
Tasks in OneHaus support rotation, so chores can be distributed fairly across household members without manual reassignment each week. The AI assistant lets you add tasks, shopping items, and calendar events using natural language rather than filling in forms. Home inventory lets you log items around the house, including warranties, documents, and expiry dates.
OneHaus is available on mobile, web and your favourite AI assistant. It's built with a privacy-first approach, keeping household data secure and not using it for advertising.

Key Differences
Task Management and Chore Rotation
Cozi's to-do lists are functional for simple household task tracking. You can assign tasks to family members and mark them complete. What's missing is any system for rotating tasks over time. If the same person ends up doing the same chores every week, Cozi doesn't help you fix that.
OneHaus includes task rotation built into its scheduling system. Chores can be set up to cycle between household members automatically, which removes the need for weekly reassignment and the conversations that tend to follow when distribution feels unequal.
AI Assistance
Cozi's free tier has no AI features. Cozi Gold includes SmartAdd, which lets you type a natural language phrase like "Date night October 28 6pm" to create calendar events. Cozi Max adds AI-powered event import from emails and photos, a recipe creator, and a meal planner. These are useful additions, but they are focused on calendar and meal planning rather than general household management.
OneHaus includes a conversational AI assistant that works across all areas of the app. You can type something like "remind me to service the boiler in October" or "add milk and bread to the shopping list" and the app handles the rest. The AI covers tasks, shopping, calendar, and inventory in a single interface, rather than being limited to one feature area.
Home Inventory
Cozi is focused on scheduling and lists. There's no place within the app to record information about your home, appliances, vehicles, or other assets.
OneHaus includes a home inventory feature that lets you log household items alongside relevant details such as warranty expiry dates, purchase receipts, and supporting documents. This is particularly useful when you need to find a warranty quickly, track when a service contract runs out, or keep records organised in one place.
Interface and Design
Cozi's interface has remained broadly consistent over the years. It's familiar to long-term users, which is a genuine strength. The trade-off is that it can feel dated compared to more recent apps, particularly on mobile.
OneHaus has a modern, clean design built with current mobile conventions. For households switching from older apps, the interface feels noticeably different in how quickly you can move between features and add information.
Where Cozi Works Better
There are situations where Cozi is the more practical choice.
The free tier covers the basics. A family can use the shared calendar (limited to 30 days ahead), shopping lists, and to-do lists at no cost. For households that mainly plan week to week, this is often enough. Cozi Gold adds full calendar access, ad removal, and SmartAdd, while Cozi Max adds AI features for events and meal planning.
The track record matters too. Cozi has been operating for a long time, which gives it a reliability profile that a newer app hasn't had the opportunity to establish. For households that have been using Cozi for years and are happy with what it does, there's no reason to switch unless you need something it doesn't offer.
Finally, for households that genuinely only need a shared calendar and a shopping list, Cozi's simplicity is an advantage. More features aren't always better if the household doesn't need them.
Where OneHaus Works Better
OneHaus covers ground that Cozi doesn't reach.
The AI assistant makes adding things faster. Whether it's a task, a calendar event, or a shopping item, natural language input is quicker than navigating menus. For households where capturing information quickly matters, this reduces friction.
Task rotation is a meaningful improvement over basic to-do lists. Households with recurring chores that need to be shared fairly will find OneHaus's rotation system handles this without manual effort each week.
Home inventory is absent from Cozi entirely. If you want a single place to track appliances, warranties, vehicle details, and household documents, OneHaus provides that alongside the rest of its features.
The privacy approach also differs. OneHaus doesn't rely on advertising, which changes the relationship between the app and your household data.
Who Should Choose Cozi
Cozi is a good fit for families that want a simple, free shared calendar and basic lists without needing anything more involved. It also suits households that are already using Cozi and happy with it. There's no practical reason to move if the current setup works.
Who Should Choose OneHaus
OneHaus suits households that have outgrown basic list apps and want AI assistance, task rotation, and home inventory tracking alongside a shared calendar and shopping lists. If you've been maintaining separate tools for tasks, shopping, and inventory, and want to bring them together into one app, OneHaus is designed for that. It's also the better option for households that prefer an app without an ad-supported model.
