Best free co-parenting apps in Australia (2026)

Genuinely free co-parenting apps got rarer in 2026. The two most commonly recommended free options both closed their free plans this year, AppClose on 1 January and TalkingParents on 30 March. Neither is free now.

What is still free in Australia is a shorter list: KidsFirst, which gives both parents messages, calendar, expenses and documents with no paid tier and no second bill, and rewrites a hostile message before it reaches you rather than warning the sender; BestInterest, which has a broad free tier but charges for its message-tone features; and Cozi, free with ads for shared calendars. Which one is right depends less on the feature comparison than on what is actually going wrong between you and your co-parent, so this guide is organised by what each app is best at rather than ranked one to seven.

The apps, by what each is actually best at

App	Free in Australia, 2026	Best for	What it does not do
KidsFirst	Yes, every feature, both parents, no second bill	Everything the paid apps charge for, messaging, calendar, expenses and documents, free for both parents, plus the one thing none of them do: hostile messages are rewritten before they reach you, not flagged for the sender to ignore. Messages cannot be edited or deleted once sent, and a full thread exports as a timestamped PDF	No call recording. Newer than the incumbents
BestInterest	Yes, with limits	A broad free tier: messaging, calendar, tasks, expenses, journal, exports	Its message-tone features are paid-only, from USD $9.99 a month
Cozi	Yes, ad-supported	A shared family calendar, simply	Built for families under one roof. No conflict tooling, no separate parent accounts, no expense splitting. Gold is USD $39 a year
OurFamilyWizard	No	The name lawyers, mediators and courts know best, and two decades of track record	AUD $199.99 to $399.99 per parent per year by tier. Hardship program
TalkingParents	No, ended 30 Mar 2026	Accountable Calling, which no free app matches	USD $7 / $16 / $32 per parent per month. Limited, temporary waivers
AppClose	No, ended 1 Jan 2026	A broad, mature feature set from a long-established app	USD $7.99 per parent per month on web, $8.99 in-app. Free accounts for hardship and DV survivors
2houses	No, 14-day trial only	One subscription covering both parents	USD $169.99 a year for the whole family ($14.17 a month), not per parent. Only one parent needs to subscribe

All prices checked 4 September 2026 against each company’s own pricing page.

Why the free list is shorter than it was. AppClose ended its free plan on 1 January 2026 after around a decade free, and now costs USD $7.99 per parent per month, $6.99 prepaid yearly. TalkingParents ended its free plan on 30 March 2026, and now runs USD $7, $16 or $32 per parent per month by tier. Both still offer fee waivers, applied for, for financial hardship and for parents in domestic violence situations. If money is the reason you are reading this, check those before you assume the paid apps are out of reach, because a waiver on an app you already know may beat migrating. Checked 4 September 2026, and both companies publish current pricing on their own sites. We have written separately about both changes: Is AppClose still free? and TalkingParents free plan ended.

And check what “free” actually covers, because a free trial is not free and freemium is not free. Five questions sort the genuinely free from the nearly free:

1. Can both parents message on the free plan? One-sided is not a co-parenting app.
2. Is the shared calendar editable by both parents, or read-only for one?
3. Can you log an expense and attach a receipt without paying?
4. Can you store documents, and how much?
5. Can you export your own records on the free plan? If export is paid, your history is hostage to a subscription you may not always be able to afford.

Best known to courts and lawyers: OurFamilyWizard

If your matter is going to court, OurFamilyWizard is the most familiar name in the room. Two decades of use, and a record format that Australian family lawyers, mediators and courts have seen many times before. That familiarity is real, it is worth something on its own, and it is not something a newer app can simply claim. It is also the reason to ask your own lawyer before you choose anything.

In Australia it runs from AUD $199.99 per parent per year on Essentials to $399.99 on Max, with Premium in between, and cheaper two-year terms. Each parent needs their own subscription, though one can pay for both. There is a 30-day money-back guarantee, plus financial hardship and military discount programs. Checked 4 September 2026.

Worth knowing before you assume you have to pay for this. What a court or a lawyer actually needs from the app is narrower than the price gap suggests: a message record that cannot be altered after the fact, and a way to get it out with timestamps attached. An Australian family lawyer wrote to us in July 2026 saying most of her high-conflict parenting clients needed exactly that, messages that cannot be deleted and a simple way to download them as a PDF, and that everything else was a bonus. We built the export because she asked for it, and it is on the free plan for both parents.

We are not claiming that makes us the safer choice for a court matter. OurFamilyWizard has the track record and the professional familiarity, we do not, and whether a given record suits your matter is your lawyer’s call. The point is only that “we need something for court” and “we have to pay hundreds of dollars a year each” are not the same sentence.

Best if you need recorded calls: TalkingParents

Recorded calling is the feature no free co-parenting app matches, ours included. If phone calls with your co-parent are part of the problem and part of the record, this is a real reason to pay, or to apply for their fee waiver. USD $7 / $16 / $32 per parent per month by tier, checked 4 September 2026.

Best for a simple shared family calendar: Cozi

Cozi is a well-made shared calendar and list app, and plenty of separated parents use it happily for exactly that. Worth being clear about what it is not: it was built for families under one roof. There is no conflict tooling, no separation between two parent accounts, and no expense ledger built for splitting costs between two households. If your co-parenting is amicable and you just need one calendar you both see, that may be all you need.

Cozi’s free version is ad-supported. Cozi Gold, at USD $39 a year, removes the ads and adds month view on mobile, calendar search and a few extras. Checked 4 September 2026.

Best if messages are where it keeps breaking down, and you want the full set free for both of you: KidsFirst

This is ours, so weigh it accordingly.

Everything the paid apps on this page charge for, free for both parents, plus the one thing none of them do: a hostile message is rewritten before it reaches you, not flagged for the sender to send anyway.

All-in-one is not our invention. Messaging, a shared calendar, expense tracking and document storage are the category standard and every paid app here has them. What is unusual is getting the complete set with nothing held back: no trial, no credit card, no ads, no paid tier. We are not run to make a profit, so there is no business reason to put anything behind a paywall, and the core co-parenting tools will stay free, always.

“Both parents” is carrying more weight there than “free” is. Most of the paid apps here bill per parent, so the advertised price is half what a separated family actually pays. 2houses is the honourable exception, one subscription covers everyone. Per-parent pricing creates the failure that quietly kills these apps: one parent subscribes, the other refuses, and either the tool half-works or the first parent ends up paying for their ex’s account. There is no second bill here, so there is no second-parent problem.

The genuinely different part is the AI Conflict Filter, and the difference is not that we have AI. Several apps do now. Everywhere else the app reads the tone and warns the person typing, who can dismiss the warning and send it anyway. We rewrite it before it is delivered. The rewrite is required, only the rewritten version reaches the other parent, and the filter cannot be switched off. That matters because a warning depends on the other parent choosing to behave at eleven at night after a bad handover, and a filter does not depend on anyone’s goodwill.

What reaches you has already been through the filter. You do not see what the other parent typed in anger.

It does not change your facts: the pickup time, the date and the request go through unchanged. What it takes out is the part that starts the next fight.

Alongside it, topic-based threads, so school, health, handovers and expenses each get their own conversation instead of one endless scroll. We are not trying to get you and your co-parent to reconnect, and we do not believe an app can do that. We organise around the child’s logistics, because that is the part that has to work whether or not the two of you are ever on good terms.

On the record, since that is usually the reason people pay. Messages cannot be edited or deleted once sent, by either of you, and a full thread exports as a timestamped PDF, both on the free plan and for both parents. That is the combination the family lawyer above asked us for.

The second difference: it is community-built. A lot of what is in the app is there because a parent using it asked for it: PDF conversation export, email notifications, repeating calendar events, picking your child’s colour. Parents tell us what is not working, we build it, and we name it in the release notes. We are Australian, and support is answered by the people building the app.

What we do not have:

• No call recording: TalkingParents has it, we do not.
• A shorter track record: we are newer than the incumbents. If long familiarity is what reassures you, that is a fair thing to weigh.
• No payment processing: expense tracking records who owes what, it does not move money.

On data. We are asking you to keep a record of your family life in an app and to let an AI read your messages, so, in specifics rather than adjectives:

• No one on our team can read your private records. That is enforced by how the app is built rather than promised in a policy.
• Personal details such as names and contact information are removed before a message reaches the AI, so the filter works on the tone rather than on who your family is. That removal is automated and best-effort rather than perfect, and we would rather tell you that than claim otherwise.
• Your data is stored in Australia, on AWS, and your messages are processed within AWS. We never train AI on your private messages, we do not sell or trade your data, and we do not run ads.
• We comply with the Privacy Act 1988 in Australia, the Privacy Act 2020 in New Zealand, and the PDPA 2012 in Singapore.

Plenty of the paid apps here do much of that too, and we are not going to claim otherwise. We would just rather say it plainly than leave you to assume. The rest, including encryption and the location data on photos you share, is in our Privacy & Disclaimer Statement, and how we are funded is in Why is KidsFirst free?

What Australian parents specifically should check

• Both stores, both parents: Australia skews heavily to iOS, but your co-parent may be on Android. Check the app is on both the App Store and Google Play before you propose it, because “I couldn’t get it” is an easy out.
• Pricing is often in US dollars: most of these apps are American. A quoted US$7.99 a month is more than that on your card, and it moves with the exchange rate. Per parent, per month, in USD, is three multiplications away from what you actually pay.
• Australian privacy law: if where your family’s data is held matters to you, check whether the app is covered by the Australian Privacy Act 1988 and where the data is stored. KidsFirst runs on AWS infrastructure primarily in Australia.
• Your court or mediator may have a preference: some Australian family law practitioners and mediators are used to particular apps and particular record formats. If you have a lawyer or a mediator, ask before you choose. It is a two-minute question that can save a migration.

Nothing here is legal advice. We are a tool, not an adviser, and family law differs by state and by country.

How to actually get your co-parent to use one

The most common way this fails has nothing to do with the app. One parent installs, the other does not, and you are back to text messages within a fortnight.

What tends to work:

• Frame it as logistics, not as a fix for the relationship: “the app we were using has gone paid, this one is free, can we try it for the school stuff.”
• Check whether “free” covers both of you: most paid apps here bill per parent, so your co-parent is being asked for their own subscription, not to join yours. That hands them a refusal that costs nothing to justify, and it is the single most common reason one of these apps never gets off the ground.
• Start with one small real thing: the next handover change, the next school date. Not a fresh start conversation.
• Do not make it a condition or an accusation: an app proposed as evidence gathering will be refused as evidence gathering.
• If there is a court order or a lawyer involved, ask them first: a recommendation carries weight yours will not.

Common questions

What is the best free co-parenting app in Australia in 2026?

There is no single best one, it depends on what is going wrong. KidsFirst gives both parents the full set, messaging, shared calendar, expenses and documents, free with no paid tier, and its AI Conflict Filter rewrites a hostile message before it reaches the other parent rather than warning the sender and letting them send it anyway. If you need recorded calls, TalkingParents is the only real answer and it is not free. If your matter is going to court, OurFamilyWizard is the name lawyers and courts know best, and it is not free either, so ask your lawyer what your matter actually requires. For a simple shared family calendar, Cozi does that well.

Are there any completely free co-parenting apps left?

Fewer than there were. AppClose ended its free plan on 1 January 2026 and TalkingParents on 30 March 2026. KidsFirst is free, every feature and both parents, with no trial and no credit card. BestInterest has a broad free tier too, and Cozi is free with ads. Read what a free plan actually includes before committing: BestInterest’s free tier, for instance, does not include its message-tone features, which are on the paid plans. Checked 4 September 2026.

Is OurFamilyWizard free?

No. OurFamilyWizard is a paid subscription, from AUD $199.99 to $399.99 per parent per year in Australia depending on tier, and it runs a financial hardship program. It is the name Australian lawyers, mediators and courts know best, which is worth something on its own. It is not the only app that keeps a record you can hand over, though, so ask your lawyer what your matter actually needs. Checked 4 September 2026.

Can I use a free co-parenting app for court in Australia?

Ask your lawyer. Australian courts and practitioners are often familiar with particular apps and record formats, and OurFamilyWizard is the best known there. What a lawyer usually needs from the app itself is narrower than the price gap suggests: a message record that cannot be altered after the fact, and a way to export it with timestamps. Several free apps do that, KidsFirst included, where messages cannot be edited or deleted once sent and a full thread exports as a timestamped PDF on the free plan. Whether a given record suits your matter is still a question for your lawyer. Nothing on this page is legal advice.

Do both parents need the same app?

Yes. A co-parenting app only works if both parents are in it. That is why free matters more than it looks: it removes the easiest reason for the other parent to decline.

Where to start

Pick the one thing that is actually going wrong. If it is recorded calls, that decides it for you and the answer is not free. If it is a court matter, ask your lawyer which app they prefer before you install anything. If it is that messages keep escalating, compare what each app does with a hostile message, not how many features it lists, because most of them warn the sender and send it anyway.

Then run your shortlist through the five questions above, and check the app is on both the App Store and Google Play before you raise it with your co-parent. Propose it as logistics, and start with the next school date rather than a fresh start conversation.

If your current app is the one that changed, we have written up both: Is AppClose still free? and TalkingParents free plan ended.
