Coparity vs Kidtime: what each app is built for
If you're choosing between Coparity and Kidtime, you're probably doing it at a point where nothing feels simple. Both apps do the same broad job — a shared calendar, messages that stand as a record, a place for the children's details — and either one will be an improvement on texts and memory. The useful question isn't which has more features; it's what each was built to be good at, and which of those is closer to your family's week.
Coparity is built for
Coparity is built for the child's everyday life in the UK: a 12-section Parenting Plan Playbook agreed provision by provision, where agreeing a provision writes the live setting — the custody pattern, the expense split, the notice periods — so the plan and the calendar can't quietly drift apart. The home screen opens on where the children are now and what still needs packing for the next handover, not on a scoreboard.
Kidtime is built for
Kidtime, made by VMGM Software LLC in the US, is built for parents who need a clear, documented record of how co-parenting is actually going — a custody calendar with templates, documented messaging, and a Premium tier that adds analytics, exports, expenses, recorded calls, attorney access and its Tone Meter. It's US-first, with state-specific parenting plans.

What two parents pay
- Coparity · One price per space; both parents included
- £12 a month
- Family £12/mo after a 14-day trial
- Kidtime · Freemium, per parent — the other parent can stay free
- $0–$17 a month
Free: calendar (a rolling ~7-week window), messaging, notes, file vault
Premium $99.99/yr per parent, often discounted; 7-day trial
Premium adds analytics, exports, attorney access, Tone Meter, recorded calls, expenses
The two are priced on different shapes, so compare them against your own situation rather than head to head. Coparity is billed per family space: a 14-day trial with no card, then one Family plan at £12 a month that covers both parents, whatever each of you uses. Kidtime is freemium and billed per parent: there's a free plan, a 7-day trial, and Premium at $99.99 a year per parent (often discounted) for the features listed on its higher tier — and the other parent can stay free. If neither of you needs Premium, Kidtime can cost nothing; if you both do, you're paying twice.
Kidtime may suit you better if…
- Your family is in the US, or your arrangements are written against a particular state's rules. Kidtime's parenting plans are state-specific; Coparity is written for England and Wales.
- You need to start without paying anything. Kidtime has a free plan — calendar, messaging, notes and a file vault — and the other parent can stay on it.
- You want to make or record calls inside the app, or settle money between you without leaving it. Coparity doesn't do either.
- A grandparent, nanny or other trusted adult needs their own access to the schedule. Kidtime supports third-party access; Coparity's space is for the two parents and their own representatives.
Coparity may suit you better if…
- You're in the UK and want one price for the family rather than a subscription each, with both parents on the same features.
- You want the parenting plan to be something you both agree line by line and then actually live by, with amendments and full history, rather than a document that's drafted once and filed away.
- You want your solicitor in a private thread alongside your own records, with a brief you prepare for them — not only read-only access.
- You'd like the app to notice things early on the child's behalf — a pattern building up before it becomes an argument — and you want your own journal and reflections to stay yours alone.
Whichever you pick, the thing that matters is the same: a child who knows where they're going on Friday, who doesn't have to carry messages, and who gets to finish the thing they're in the middle of.
Is Kidtime a good fit for UK parents?
It can be — it's a capable calendar-and-messaging app and nothing stops you using it. But it's made by a US company, built US-first, and its parenting plans are state-specific, so some of the framing won't match England and Wales. Coparity is written for the UK and priced in pounds.
Which one is cheaper for two parents?
It depends entirely on whether you both need the paid tier. Kidtime can be free for one or both of you, and its Premium is charged per parent per year; Coparity is a single £12 a month for the space, with both parents included. Compare what each of you would actually use before deciding.
Can I use either app if my co-parent won't join?
Yes. Both work for one parent on their own. In Coparity you get the complete product solo, and everything you've built waits for the other parent if and when they join.
Does either produce a court-ready record?
Neither Coparity's Snapshot nor its full data export is certified, and we'd never promise that a record decides anything. Kidtime offers exports on its higher tier. If a court or a professional has asked for records in a particular form, ask your solicitor or mediator what they need before you choose.
Can my solicitor get involved in either app?
Both offer professional access — Kidtime's attorney access sits on its higher tier. The difference is what your solicitor gets: in Coparity it's a private 1:1 thread, read-only access to what you can see, and a brief you prepare for one named representative. None of it is visible to the other parent.
