Casewell
There is no national custody rule
Custody law is state law, and procedure often changes by county. The order or parenting plan that applies to you matters more than anything written for a national audience.
Start there. Use the words your own order uses, whether that is legal custody, physical custody, parenting time or possession and access. Put your state and county on anything you hand to a professional.
Many states also require mediation, a parenting class, or both before a contested custody hearing. Ask your attorney or check your court's self-help pages for the local sequence.
Pick the app around what your attorney can use
Attorneys bill by the hour, and a folder of 3,000 screenshots costs you money before it proves anything.
The useful skill is leaving things out. Choosing the six entries and three files that answer one question is the work, and that is what to test an app on.
Check the export, not the entry screen. A useful PDF shows the date the event happened and the date you wrote it down, keeps the file with the entry it explains, and can be filtered down to one child, one category, one date range.
Your journal can show up in discovery
This should change how you write every entry. In a contested case, the other side can request documents, and a journal you rely on is a document.
Write for two readers: assume the other parent's attorney and the judge will both see it. Stick to what happened, what you saw, and what the attached file shows. Leave out the diagnosis of the other parent's character.
Once a case has started, ask your attorney before deleting anything. Destroying records mid-case can cause more damage than the records ever would. Casewell reports also state how many matching records were left out of a selection. So a short export doesn't pretend to be the whole archive.
Custody evaluators and guardians ad litem read what's filed
Depending on your state and your judge, a custody evaluator, a guardian ad litem or a court services investigator may be appointed. They interview the parents, often see the children, and review the material in the case.
They are not there to read your entire phone. A parent who arrives with a filtered timeline and a handful of labelled files is easier to work with than one who forwards everything.
So a journal is not something you dump on an evaluator. Its job is earlier: keeping the facts straight for your attorney, and letting you answer questions about dates without guessing.
Recording the other parent is not the same in every state
Parents often reach for an app because they want proof of a phone call. Federal law permits recording a call you are part of. But state law can be stricter, and some states require every party to consent.
The penalty for getting this wrong is not just an unusable recording. In some states it is a crime, and in others it carries civil damages per violation.
The safe substitute is the thing a journal is for. A dated note written while the conversation is fresh, saying what was said and when you wrote it. Check your own state's rule with an attorney before you record anything.
Casewell — best for a private record your co-parent never has to join
Casewell is designed for a private record when the other parent does not use a shared platform, or when you want your own account of events.
You can log missed exchanges, parenting time, incidents, communication and expenses, with files kept in a private vault.
When your attorney, a mediator or an evaluator needs context, export a PDF filtered by date range, child and category. Review the selection and the report before sharing it.
It costs $2.99 a week or $49.99 a year, with a 14-day trial. One payer, because there is no second parent on the account.
OurFamilyWizard — best when a judge orders a shared platform
OurFamilyWizard is a shared co-parenting platform. Both parents get accounts and message through it, with ToneMeter flagging wording before it's sent. It adds a shared calendar with time trades, expense tracking with payment splits, and an Info Bank for school and medical details. If a court order specifies a platform, follow its terms.
Pricing is per parent. Plans run from $110 to $299.88 each per year, so two parents on the middle plan is roughly $430 a year between you. Professional accounts for attorneys and mental health practitioners are free.
The rest, and how they land here
Custody X Change is the other app that works alone, and it is the strongest pick if your fight is about percentages. It builds the parenting plan, counts overnights and prints the totals, from $6 a month billed annually.
TalkingParents runs an unalterable message and call record, from $7 a month, with unlimited PDF records starting on the Enhanced plan. AppClose is a low-cost all-inclusive shared option at $7.99 a month after a 60-day trial, with fee waivers for parents in hardship and domestic violence survivors.
2houses bills one subscription per household rather than per parent, and SupportPay is the better fit when the dispute is really about reimbursements rather than messages.
If a court order already names a platform
Use it, exactly as ordered. An order that says to communicate through a platform is not satisfied by texting and keeping your own notes.
Keep the two jobs separate. The ordered platform carries the messages between you. A private journal carries what the message feed never sees. The handover that ran 40 minutes late, the receipt nobody acknowledged, the week the schedule quietly changed.
Plenty of parents in high-conflict cases end up paying for both, and that is a reasonable outcome rather than a failure.
How to choose, in five minutes
If a court order or your attorney names a platform, use that platform, and keep your own notes somewhere separate where they can't be read or derailed.
Co-operating parents who mainly need calendars and messages can start with AppClose. Move up to OurFamilyWizard or TalkingParents when you need ToneMeter or an unalterable calling record.
When the argument is about percentages of parenting time, Custody X Change counts it for you.
When you need your own dated record with the files attached, that's the job Casewell was built for. Start the trial, log two weeks of exchanges, and export a sample PDF to see whether your attorney could use it.
What this looks like in Casewell
Casewell keeps the dated entry, the file that supports it and any later addition in one private timeline. Filter by date range, child and category, then export a PDF short enough for an attorney, a mediator, or your own preparation.
Try for freeWhat is the best custody journal app in the US?
For a private record that works without the other parent, Casewell is built for that purpose and lets you export a filtered PDF for attorney review. If a judge has ordered a shared platform, follow the order. OurFamilyWizard and TalkingParents both offer shared messaging.
Which app works if my co-parent refuses to join?
Casewell and Custody X Change both work on their own. Casewell is a single-parent app by design, with nothing for the other parent to join or see. OurFamilyWizard, TalkingParents, AppClose and 2houses only deliver their core value when both parents take part.
Can the other parent get my journal in discovery?
Possibly. In a contested case the other side can request documents, and a journal you rely on is a document. Write every entry expecting it may be read, and ask your attorney before deleting anything once a case has started.
Is there a free custody journal app?
Not really, once you look closely. AppClose gives you 60 days and keeps fee waivers for parents in hardship and domestic violence survivors. Casewell has no free tier: it's a 14-day trial, then a paid plan.
Will a custody journal be accepted by the court?
A judge decides what's relevant and admissible in each case, and rules vary by state. What an app can do is keep entries dated, factual and easy to review, and show when an entry was written and later edited.
Can I record calls with my co-parent instead?
Check your state first. Federal law allows recording a call you're part of. But some states require everyone's consent, and getting it wrong can be a crime. A dated written note made the same day is the safer record.
