What to do when the other parent won't use a co-parenting app
You want the structure of an app. They've said no. Three honest truths, in order: you can't force them, a surprising amount works with one parent, and how you invite matters more than whether you keep asking.
First
You can't make them — and pushing usually escalates.
It's worth saying plainly, because it's the bit that hurts: there is no way to require the other parent to download an app. Repeated asking becomes its own conflict, and the argument about the app quietly replaces the thing the app was meant to calm down.
So park the campaign. What follows is what you can do on your own today, how to invite them in a way that might actually land, and what to do if the answer stays no.

What genuinely works with one parent.
In ParentGlow, one parent can set up the family and be using it within minutes. The invite to the other parent is a short code you share however you like — and nothing waits on them. On your own you can keep:
Your own dated record of what actually happened
The schedule as it really ran, handovers made and missed, a private journal only you can see, and a per-child care log that can't be edited once written. Everything is timestamped when you write it.
Your household's calendar and holiday plan
Build the parenting pattern and the school-holiday breaks now, against a clearly labelled "co-parent (pending invite)" placeholder. If they join later, the app stitches them into it — you don't redo anything.
Your children's details, in one place
NHS numbers, GP, school, allergies, medicines, the emergency card — none of it needs a second parent to exist.
An expense log with receipts
Log what you paid, attach the receipt, tag it by child. What you can't do alone is split or settle it — that needs someone on the other side.
Clean exports, free, whenever you want
Calendar, messages, expenses, or one complete record pack — dated, unedited and tamper-evident, aligned to the family court's PD 27A bundle format. Your record is yours to take, free, forever. How court-ready records work.
What doesn't work solo — no weasel words: messaging is a two-person feature. You can write, and Tone Guard will still check your draft, but there's no conversation until the other parent joins. Splitting and settling money needs both of you. Swap requests need someone to say yes. And ParentGlow can't reach a parent who never installs it — there's no email or text bridge to a person who isn't there. Anything you set up alone is recorded honestly as set up by you before your co-parent joined; the app will never make a one-sided record look like an agreement.
The ask
How to invite them so they might actually say yes.
The framing matters more than the frequency. Blame-free, practical, and ideally not coming from you.
Make it about the admin, not about them
"One place for the kids' stuff so neither of us is digging through texts." "It's cheaper than paying twice for anything else — one plan covers both of us." "The school dates and the inhaler doses in one spot." No history, no subtext.
Let a neutral messenger suggest it
A mediator's or solicitor's suggestion lands very differently from another message from you. If you're in mediation, ask the mediator to raise it. Our mediation guide explains how that works.
Offer a no-risk try
ParentGlow is free during early access, and one plan covers both homes — there's nothing for them to pay and nothing to lose by looking. Share the invite code and leave it with them.
If it's still no
Practical fallbacks.
Keep your records anyway
They're yours, they cost nothing to keep, and they're the thing you'll be glad of in a year. Our guide to what records to keep covers the five that matter.
Route handovers through a third place
If direct contact is the problem, school as the exchange point, a trusted relative, or a contact centre's handover service takes the two of you out of the room. See calmer handovers.
Revisit at natural reset points
Mediation, a new school year, a change of arrangements. A no in March is not a no forever — but the ask should come at a moment that makes sense, not weekly.
If you're stepping back from contact altogether while staying fully involved with the children, that has a name and a structure — see parallel parenting.
One careful paragraph
When refusal is about control.
Sometimes "no" to a neutral, record-keeping app is part of a wider pattern — of not wanting things written down, or of keeping you off balance. We're not going to diagnose anyone from here. But if that's what this feels like, it's bigger than an app.

Quick answers
The questions parents ask when their co-parent won't join.
Do both parents need to use a co-parenting app?
For messaging, splitting money and agreeing swaps, yes — those are two-person features. For your own records, your children's details, your household calendar and holiday plan, your expense log and your exports, no — one parent can start alone in ParentGlow, and the other is stitched in when they accept the invite.
Can I make my ex use a co-parenting app?
No — and repeated asking usually escalates. A suggestion from a mediator or solicitor often succeeds where a direct ask doesn't, and courts in England and Wales sometimes encourage written, app-based communication in child arrangements cases. That's general information, not legal advice about your case.
Is a one-sided record still useful?
Yes. A dated, consistent, unedited record of what happened and what you sent is far better than reconstructing events months later — for mediation, for a solicitor, and for your own peace of mind. It stays yours to export, free, whenever you need it.
What if I'm worried about why they're refusing?
If saying no to neutral record-keeping is part of a wider pattern of control, that's not an app problem. Speak to the National Domestic Abuse Helpline on 0808 2000 247 (free, 24 hours), Women's Aid or the ManKind Initiative, and call 999 in an emergency. An app is not a safety plan.
