In their own words

BestInterest

BestInterest is a co-parenting app for separated parents to communicate and organize parenting details. It combines secure messaging with a shared custody calendar, schedule changes, tasks, and tracking for child-related expenses and receipts. Message Shield filters harmful wording before a message is read, while Tone Guardian suggests a calmer draft. Solo Mode lets one parent use coaching, organization, and documentation tools without the other parent joining. Supported records can be exported as CSV; Connect and higher plans also provide structured PDF Verified Reports, though admissibility depends on the facts and jurisdiction. In-app audio and video calls are available, and Protect Plus adds recording and transcription for supported calls. Journal entries, Coach conversations, and unsent drafts remain private from the co-parent; sent or deliberately shared content is visible. The app has a Free plan at free with no expiration. Paid plans start at $9.99 a month, and paid tiers include a 14-day trial. Mobile users can disable usage-data collection in Privacy Options.
