Nara includes unlimited caregivers and Apple Watch support in its paid plans. After the seven-day trial, a plan is needed to add new entries; existing records remain viewable and exportable. Cocoon is free right now and supports importing Nara CSV exports. Cocoon offers planning estimates with a published method, a private journal and checkup reports, but does not yet offer an Apple Watch app or infant growth percentiles. Growth is recorded below age two, with CDC percentiles from age two.
