Is OnePage cheaper than BestInterest?

OnePage is free for the core calendar and messaging, with Plus at $11.99/mo or $99.99/yr for both parents. BestInterest's current published pricing is free; connect $9.99/mo, protect $14.99/mo, or protect plus $29.99/mo, with annual options. The lower total depends on the tier, billing period, number of paid users, and features your family actually needs.

Does my co-parent need their own BestInterest subscription?

No. Each parent can choose their own plan; a linked co-parent can remain on Free while the other parent subscribes.

Can I switch from BestInterest to OnePage?

Yes. OnePage doesn't import data from other apps automatically today, but setting up a new shared calendar, message thread, and expense log takes a few minutes. Many families run both briefly during a transition.
