Questions & Answers

As answered by people managing Data Protocol and Larkling.

What makes your product unique?

Larkling'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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

Larkling's answer:

A progressive web app (PWA) that works in any browser. Backend on Supabase (PostgreSQL) with EU data storage in London (eu-west-2) for UK GDPR compliance. Served via Cloudflare Workers and Pages. AI Tone Coach built on LLM-based message rewriting. No native app required — installable on iOS and Android home screens.

Who are some of the biggest customers of your product?

Larkling's answer:

Individual co-parenting families across the UK, Europe and US LGBTQ+ and blended families who need inclusive co-parenting tools Single co-parents using Solo Mode to keep a record when the other parent won't engage Family-law mediators and solicitors who recommend a reliable, low-cost record-keeping option Community and support organisations signposting free tools to separating parents
