Search for a "co-parenting app" in 2026 and you land in two worlds that don't talk to each other. On one side, two-household organizers: custody calendar, shared expenses, journal — logistics. On the other, tools built for litigation: certified messaging, recordings, tamper-proof histories — evidence. Between the two sits a question neither side asks: who keeps thinking about everything, including the week the children aren't there?

This comparison reviews the apps available to separated parents (with a French-market focus), prices verified in August 2026, and one criterion you won't find in any other comparison: the measurement of the mental load.

Two families of apps — and a blind spot

Two-household organizers (2houses, Coot, Kiido, Share(d), 2forkids, My Familiz…) assume co-parenting is a coordination problem: a shared custody calendar, expenses to split, information that must flow without passing through the child. That's essential — and it's exactly what family mediators recommend to escape the child-messenger trap.

Documentation machines (OurFamilyWizard above all) assume the opposite: co-parenting is a potential conflict, and every interaction must be producible before a judge. Tamper-proof messaging, certified timestamps, tone analysis of messages, GPS check-ins at handovers. Formidably effective in litigation — but structurally pessimistic: the tool writes every exchange for a hypothetical courtroom.

The blind spot both families share: neither measures the invisible work. A custody calendar says where the child sleeps; it doesn't say who thought of the vaccine booster, who filled in the re-enrolment file, who noticed the trainers were too small — or during whose custody week that work was done. Yet that imbalance is precisely what wears co-parents down, as we detailed in mental load and shared custody: the 50/50 myth.

The 6 comparison criteria

Real price. Per family or per parent? The range runs from €0 to $600 a year for two parents.

Custody calendar. Handling of alternation rhythms (alternating weeks, 2-2-3, every other weekend…), exceptions and day swaps.

French school calendar. Zones A/B/C and public holidays built in — the real life of shared custody in France gets planned around school holidays.

Shared expenses. Entry, splitting and reimbursement tracking between the two households.

Messaging and "court" evidence. Traced, timestamped communication, possibly producible in court.

Mental load measurement. The novel criterion: does the tool show who anticipates, decides and checks — and during whose custody days?

2houses — the logistics reference for two households

A European pioneer of the category, 2houses covers the essentials of coordination between separated parents: a shared custody calendar with change requests, a finance module (expenses, support payments, reimbursement requests), an information journal and photo albums so both households follow the child's life. Pricing is family-wide — €8.25/month or €99/year for everyone, however many parents and step-parents — making it one of the best feature-to-price ratios on the market. Choose it if your co-parenting works and you want a complete, proven logistics tool. Its limit: it organizes, but measures nothing — neither the split of the piloting nor the load each parent carries.

OurFamilyWizard — the documentation machine for high-conflict situations

The American OurFamilyWizard is the tool for high-conflict co-parenting: tamper-proof messaging with read receipts, ToneMeter (an AI that flags aggressive phrasing before sending), certified records producible in court, GPS check-ins at handovers, call recording. Family court judges know it and lawyers recommend it — that's both its strength and its definition. The price follows: from $110 to $300 per parent per year depending on the tier, potentially $600 a year for the parental couple. Choose it if you're in genuine litigation where every exchange must be documented. Avoid it if your co-parenting is functional: paying two subscriptions to write every message under the eye of a hypothetical judge builds distrust into your daily tool.

Copareo — French-style timestamped evidence, one-time purchase

Copareo takes the legal niche from the minimalist angle: €6.90 as a one-time purchase (no subscription), with an explicit positioning of timestamped evidence under Article 1366 of the French Civil Code — recording a late handover, a missed exchange, a disputed expense. Choose it if you occasionally need to timestamp facts without paying for an OurFamilyWizard subscription. It is not a daily organization tool.

Coot, Kiido, Share(d) and the other French apps

The French ecosystem has grown: Coot and Éduquer Ensemble are free and cover basic coordination (calendar, information sharing); Kiido, Share(d), 2forkids and My Familiz offer freemium variants around the shared calendar, journal and sometimes expenses. Choose them if your need is simple and your budget is zero — that's already infinitely better than the child-messenger or a text thread that spirals. Their common limits: no built-in school calendar by zones, often rudimentary expense handling, and no measurement of the actual split of parenting work.

The third way: measure the load, don't manufacture evidence

Mental Loadless wasn't born as a co-parenting app: it's a mental load app — complete household organization plus the measurement of who thinks about what — that now extends its measurement to shared custody. The link between the two households is explicitly consented, covers one child and only four things: their homework, their calendar, the custody schedule, the expenses concerning them. Nothing else crosses over — not the household members, not the meals, not anyone's private space.

On logistics, the app matches the best in class: 7 custody patterns (alternating weeks, 2-2-3, 2-2-5-5, every other weekend, with or without a midweek day, primary residence with visits, a custom 14-day grid), the French school calendar built in — zones A/B/C across 10 school years, public holidays included, with 4 holiday-splitting rules —, a day-swap journal where nothing takes effect until the other parent accepts, and shared expenses to the cent: encrypted amounts, exact splitting, reimbursement attested by both parents.

On measurement — what no other app does — the Mental Load Index (MLI) becomes normalised per custody day: ten tasks over five days don't weigh the same as ten tasks over nine days. Above all, the app isolates the load carried outside your custody days: the paediatrician appointment booked during the other parent's week, the school file filled in from "your" week off. That number, which appears in no other tool, is exactly the invisible work that makes co-parents say "I hand back the kids, but not the load."

Two deliberate choices deserve emphasis. The compared view between households only exists if both parents switch it on, and disappears as soon as one opts out. And it cannot be exported: the app doesn't manufacture ammunition for court. If you're after a case file, OurFamilyWizard or Copareo are built for that; Mental Loadless is built to rebalance a co-parenting arrangement that wants to work.

On price, one subscription covers both households: the parent who initiates the link needs the Family plan at €12.99/month — which already covers their own household's organization and measurement — and the invited co-parent pays nothing. Compare that with the $220 to $600 a year OurFamilyWizard costs for two parents. For the full detail of the shared custody features, see our dedicated page: Mental Loadless for shared custody.

Conclusion: which co-parenting app should you choose in 2026?

Ask yourself two questions. What is your actual conflict level? Active litigation: OurFamilyWizard (if the budget allows) or Copareo (to timestamp at low cost). Functional co-parenting: an organizer is enough — 2houses if paying, Coot or Éduquer Ensemble for free. And who carries the piloting? If the answer is "always the same person, even during the week without the kids", then a shared calendar will fix nothing: you need a tool that makes that imbalance visible and measurable. In 2026, only one app measures the mental load in shared custody — and it requires just one subscription for two households.
