Flexibits has added Calendar Mirroring to Fantastical 4.1.15, giving users a built-in way to reflect events from one calendar onto another without hand-copying appointments across accounts.
The feature is aimed at a common calendar mess: people who keep separate work and personal calendars, then need each side to know when the other has already claimed their time. According to Flexibits, Calendar Mirroring connects two separate calendars so events from a chosen source calendar automatically appear on a chosen destination calendar.
That sounds mundane, which is usually where calendar software is most likely to hurt people. A missed copy, a wrong time zone, or a stale duplicate can turn into a double booking. Flexibits says the new feature keeps mirrored entries updated one way, so moving an event on Calendar A is reflected on Calendar B in real time.
How the mirroring works
Flexibits describes the feature as one-way synchronization. Users pick a source calendar, where the original events live, and a destination calendar, where the mirrored events are placed. The company gives work and personal calendars as the obvious example.
Users can also choose how much information gets copied. Flexibits says mirrored events can show full event details, or they can appear only as “Busy” blocks. The second option is the more useful one for anyone who wants colleagues to see that time is unavailable without broadcasting the reason.
The company says Calendar Mirroring does not send event information to Flexibits servers and does not save that information outside the user’s device. That is a meaningful claim for a feature that touches personal and work schedules, though users still have to consider the privacy rules of the calendar services they are mirroring into.
Setup and availability
Flexibits says users can enable the feature from Fantastical’s Settings by selecting Mirroring. From there, they choose the source and destination calendars, set the mirrored range, decide which events should be included, and choose what details are copied.
The mirrored range has a fixed look-back period: Fantastical checks two weeks into the past, then looks forward by the amount of time the user sets for the rule, according to Flexibits. After the rule is added, Flexibits says the mirroring rules sync across a user’s devices.
Calendar Mirroring is available now in Fantastical for Mac and iOS. Flexibits says Windows support is coming soon, but did not give a release date in its announcement.
The feature adds another automation layer to Fantastical’s paid-calendar pitch: fewer manual copies, fewer misleading open slots, and fewer explanations after a private appointment collides with a meeting invite. The useful part will depend on how reliably the one-way updates behave across the calendar providers people actually use.
