Shared Calendar

Coordinate custody schedules, school holidays, birthdays, and handovers in one place both parents can see. Colour-coded entries make it instantly clear who has the children when, reducing last-minute confusion and back-and-forth messages.

Set repeating schedules (alternating weeks, 2-2-3, 50/50 splits) and get automatic reminders before transitions. Changes sync instantly — no more "I thought it was my weekend" arguments.

AI Tone Coach

Typing a heated message? The AI Tone Coach analyses your draft in real time and flags language that might escalate tension. It suggests calmer, more constructive alternatives — like a wise friend reading over your shoulder.

You approve every change. The goal isn't to censor you; it's to help you communicate in a way that keeps things civil and child-focused, even when emotions run high.

Secure Messaging

A dedicated messaging space separate from WhatsApp, SMS, and email — so all co-parenting communication stays in one place. End-to-end encrypted, timestamped, and never mixed with personal chats.

Share photos, documents, and quick updates. Every message is logged with a verifiable timestamp, creating a clear record that can help if disputes arise later.

💰

Expense Tracking

Log shared child-related expenses — school uniforms, activities, medical bills, tutoring — and track who owes what. Snap a photo of receipts directly in the app and assign costs to categories for clear monthly summaries.

Settling up is simple: see the running balance at a glance, export reports, and avoid the awkward "you still owe me for football kit" conversations.

Solo Mode

Your co-parent hasn't signed up? No problem. Solo Mode gives you full access to calendars, expense tracking, and personal records without requiring the other parent to join. Everything stays private to your account.

If your co-parent decides to join later, you can selectively share calendars and expense logs. Until then, you have a complete toolkit to manage your side of co-parenting independently.

Court-Admissible Records

Premium subscribers can generate timestamped, uneditable PDF exports of messages, calendar history, and expense logs — structured in a format designed to meet court evidence standards. Each export includes cryptographic integrity metadata.

Whether you're preparing for mediation, a hearing, or just want peace of mind, having a clean, professional record of all co-parenting communication can be invaluable. Always consult your solicitor about admissibility.

LGBTQ+ Inclusive Design

Larkling was built recognising that families come in all shapes. Our interface avoids gendered assumptions — you choose your role labels (Parent, Mum, Dad, Guardian, or custom), and every screen works regardless of family structure.

From pronoun settings to non-nuclear family models (co-parenting trios, kinship carers, donor-conceived families), Larkling reflects the reality of modern parenting. No awkward "Mother/Father" defaults that don't fit your life.

❓ Common questions about Larkling

Is Larkling really free?

Yes — Larkling's core features (shared calendar, messaging, expense tracking, AI tone coach, and solo mode) are free forever. A Premium tier at £6.99/mo per family adds court-admissible PDF exports and advanced AI features. There are never per-parent fees or hidden costs.

What makes Larkling different from other co-parenting apps?

Larkling is built with an LGBTQ+ inclusive design from the ground up. It includes an AI tone coach that helps de-escalate conflict before messages are sent, a solo mode for parents managing everything independently, and court-admissible timestamped records. It's also truly free — no trial that expires.

Can I use Larkling without my co-parent?

Absolutely. Solo Mode lets you manage custody schedules, track expenses, and keep your own records independently — even if your co-parent never signs up. Everything stays private to your account until you choose to share.

Are messages and records usable in court?

Yes — Premium subscribers can export timestamped, uneditable PDF records of messages, calendar events, and expense logs that are structured in a court-admissible format. Each export includes cryptographic integrity metadata. Always consult your solicitor about admissibility in your jurisdiction.

How does the AI tone coach work?

When you compose a message to your co-parent, the AI tone coach analyses it in real time and suggests gentler alternatives if the tone is confrontational. It's like a spell-check for emotions — helping you communicate clearly without escalating conflict. You're always in control; it never changes your message without your approval.
