The most common reason co-parenting apps don't solve the problem they're designed to solve is the adoption standoff. One parent — usually the one managing most of the child logistics — sets up the account, does the onboarding, and then waits for their co-parent to download the app, create an account, and engage. The co-parent never does. The app sits unused.
Why the standoff happens
The co-parent who isn't the primary financial organiser rarely feels the same urgency. They may see the app as the other parent's tool — designed to extract money from them more efficiently. They may simply not want to create yet another account. They may be hostile to anything that makes the situation more 'official.' Whatever the reason, the result is the same: the app never gets used.
How Solo Mode works
- —You submit an expense request in FairSplit as normal — receipt photo, amount, split percentage.
- —FairSplit sends your co-parent an SMS with a professional expense summary and a unique link.
- —Your co-parent taps the link and sees the full request in any browser — no app, no account, no login required.
- —They can approve the payment (Stripe handles the transaction), dispute the expense, or leave a comment.
- —Their response is logged with a timestamp in your FairSplit account, regardless of whether they ever create an account.
What this means for the adoption standoff
Solo Mode removes the co-parent's ability to avoid the system by refusing to download the app. They receive a professional, accountable request in their SMS inbox. They can respond in seconds or ignore it — and ignoring it creates a documented record of non-response. The dynamic shifts from 'I'm chasing you for money' to 'I've sent you a formal, timestamped request and your response is on record.'
The surprising conversion rate
In practice, most co-parents who receive SMS expense requests through Solo Mode end up creating FairSplit accounts within a few weeks. Once they realise the requests are documented and their responses are recorded, there's less reason to stay outside the system than to be in it. Being in the system gives them the ability to dispute, comment, and keep their own record.
What Solo Mode doesn't replace
Solo Mode handles expense requests and payment collection. It doesn't replace direct communication for custody changes, emergency decisions, or co-parenting coordination. For parents who've established a working communication channel elsewhere, Solo Mode supplements it — it adds financial accountability to whatever communication system already exists.
