Larkling is the free co-parenting app that de-escalates conflict, not just records it. Its AI Tone Coach rewrites hostile messages into calm, child-focused ones before you hit send — catching the tone the paid apps charge $30+/mo for, included free.
Includes a shared custody calendar, secure non-editable messaging, expense tracking, a document vault, and Solo Mode (keeps a reliable record even when your co-parent won't join).
Free forever — no credit card, no per-parent fees. Built for every kind of family: LGBTQ+, blended, single, donor-conceived, and traditional. UK-founded, EU data storage, UK GDPR compliant. Premium is £6.99/month for the WHOLE family (not per parent).
After the free tier collapsed in 2026 (AppClose ended Jan 1, TalkingParents Mar 30), Larkling is the only major co-parenting app still genuinely free.
LarklingLarkling's answer
Larkling is the only co-parenting app built from day one for ALL family structures — LGBTQ+ families, blended families, single parents by choice, and traditional families alike. Key differentiators: custom pronouns and flexible roles, Solo Mode that works even when the other parent refuses to join, AI Tone Coach that helps de-escalate hostile messages before they're sent, court-ready PDF Export Packs, and a genuinely free forever core with no trial bait.
Larkling's answer
It's the only major co-parenting app that's genuinely free forever — no credit card, no trial, no hardship waiver to apply for. Most rivals went paid in 2026 (AppClose ended free Jan 1, TalkingParents Mar 30) or sit behind per-parent fees that double for two parents. Larkling includes an AI Tone Coach that rewrites hostile messages before you send (a feature rivals charge $30+/mo for), plus Solo Mode that keeps a reliable record even when your co-parent won't join — and it's built for every kind of family, not just the traditional divorced couple.
Larkling's answer
Separated and divorcing co-parents — especially LGBTQ+, blended, single, donor-conceived and other family types that mainstream apps don't serve well. Also budget-conscious parents who need a reliable record of communication, schedules and expenses without paying per-parent subscription fees. Based in the UK and Europe, with a growing US user base.
Larkling's answer
Founded by Nye Hoppie after personally hitting the "pay to send a message to your ex" wall — finding that every reliable co-parenting tool locked basic communication behind a subscription, and that most assumed a traditional heterosexual divorced couple. Larkling was built to be genuinely free, warm, and inclusive of all families, with AI that de-escalates conflict rather than just recording it.
Larkling's answer
