Our verdict on Duet

Duet is a shared family and co-parenting calendar for families coordinating across households. It covers parenting days, handoffs, holidays, events, conversations, tasks, files, and shared expenses. Separated mode adds parenting-time assignments, schedule history, pickup tools, swap requests, and Smart Proposals for 2-2-3, weekly, or custom schedules. Married mode is intended for coordination within one household, making Duet more specialized than a general-purpose calendar.

The free-to-download app has optional subscriptions for sharing and additional features. The US App Store lists Monthly Subscription and Yearly Subscription plans, along with Shared Pack, Premium Pack, and Bundle options. Bundle prices shown in the product details are $4.99 and $39.99, while regional storefront pricing can differ. Eligible new subscribers may receive one free week on monthly plans or one free month on annual plans. Buyers should review the applicable storefront before choosing a plan, particularly when comparing monthly and yearly billing.

Duet fits families already using Apple devices and services. Shared iCloud family calendars, Apple Calendar linking, widgets, Siri support, Messages, and cached offline access keep its workflow close to the Apple ecosystem. Its strongest distinction is the depth of co-parenting coordination: schedule proposals, parenting-day assignments, handoffs, expenses, and shared family information sit alongside calendar events. Choose Duet if co-parenting logistics are the main requirement and Apple platform coverage works for everyone involved. Choose another calendar app if the household needs broad cross-platform access or calendar connectivity beyond the Apple-centered setup.
