What TimeTree is designed for
TimeTree is a shared calendar app developed in Japan and released globally, with a large user base across family groups, couples, and work teams. The product organizes events across multiple calendars, lets members comment on individual events, and supports photo attachments. Shared calendars in TimeTree are not siloed to a single household type, the app works equally for a book club, a family, or a small business. The free tier is comprehensive. TimeTree Premium at approximately $4.99 per month per user removes ads and expands storage. TimeTree's popularity with co-parents comes from its quality and low cost, not from custody-specific design.
What TimeTree does well
TimeTree's event comment threads are the feature that most clearly sets it apart from other shared calendars. When a parent posts a custody exchange or school event, the other parent can respond with logistics notes directly on that event, no separate message thread needed. The visual calendar design is clean and readable across overlapping member schedules. The app is well-maintained with a stable global user base, which means it is reliable. For co-parents who genuinely need only a shared calendar with some communication around specific events, TimeTree is a high-quality free option.
Where TimeTree is thin for co-parenting
TimeTree represents custody time as events, which means the distribution of overnight time between parents is invisible in the calendar view. There is no time-share percentage counter, no overnight-aware visualization, and no mechanism for tracking which parent has had how many nights over a period. Expense reimbursement, requesting, approving, and logging child-related cost splits, is not part of the product. Joint decision proposals do not exist as a structured workflow. Step-parents and grandparents can join a shared calendar but they hold the same status as any other calendar member, with no role-based access.
Pricing reality
TimeTree is free for standard use, with TimeTree Premium at approximately $4.99 per month per user for ad removal and expanded storage. A co-parenting pair where both parents subscribe to Premium pays approximately $120 per year combined, more than most co-parenting tools charge for an entire family. Families that stay on the free tier avoid that cost but also live with in-app ads throughout the experience. The relevant pricing question is not TimeTree free vs TimeTree Premium; it is whether TimeTree at any price level delivers what a co-parenting family actually needs.
Which family fits which app
TimeTree is a good fit for co-parents who have a simple, stable custody arrangement, communicate easily enough to handle expenses and decisions outside any app, do not need overnight counts for tax or legal documentation, and have no caregivers beyond the two parents who need household access. The event comment feature is genuinely useful for casual coordination at that level. When the family situation gets more complex, overlapping schedules, reimbursement disputes, blended household members, TimeTree's design shows its limits quickly because co-parenting complexity was never part of its design brief.
How CoFam approaches the same problems
CoFam handles the shared-calendar use case TimeTree covers but with custody-specific structure underneath. The schedule is entered once as a pattern, alternating weeks, 2-2-3, or any custom rhythm, and the calendar draws overnight assignments as proportional blocks rather than manual events. Time-share percentages update automatically as time passes. Expenses flow through a reimbursement workflow with a logged history both parents can see. The household model supports up to twelve members, with distinct roles for parents and caregivers. Families who start with TimeTree and find the calendar adequate but the custody logistics unmanageable tend to add CoFam for the structured layer.
