How Sideby works

No chat. No threads. Just the logistics — handled cleanly so you can get on with your life.

Requests, not messages

Send a request that can only end in accept, decline, or counter. No threads. No essays. No "what did you mean by that?"

Handover checklists

Make handovers boring again: what was packed, what was missing, what was agreed — timestamped, consistent, factual.

Money tracker

Track owed, paid, and pending with receipts and notes — so "I already paid that" stops being a weekly event.

Built-in boundaries

Cooldowns and deadlines reduce reactive replies and stop disputes dragging on for weeks. Every request has a clear outcome.

Factual record, automatically

Export a clean timeline of what happened without digging through messages. Records are created by normal use, not "logging incidents".

Shared schedule, separate lives

See who has the kids and when. Request changes through the system, not through texts that get ignored or "misunderstood".

Built for high-conflict situations

When communication has broken down, structure provides safety. Sideby is designed to reduce contact — not increase it.

No open-ended messaging

Workflows replace conversations. There's no inbox to check, no thread to argue in, no notification anxiety.

Boundaries by design

Communication is limited to what's necessary for the children. No room for personal attacks or off-topic messages.

Predictable routines

Standard processes for common scenarios. Less room for manipulation or moving goalposts.

Cooldown periods

Built-in waiting periods prevent reactive responses. Time to think before acting.

Easy to share (if needed)

Exports are formatted for solicitors, mediators, or court. Professional, factual records ready when you need them.

Not relationship repair

Sideby isn't about reconciliation. It's about logistics and reducing friction so you can both move forward.

Sideby is not: A messaging app • Relationship counselling • Legal advice • A reconciliation tool

Frequently asked questions

No. Sideby deliberately avoids open messaging. Instead, you submit structured requests with specific categories and outcomes. There's no inbox, no chat thread, no way to send free-form messages. This is by design—to reduce conflict, not enable it.
No. Sideby is an organisational tool, not a legal service. We don't provide legal advice, and nothing in the app should be taken as such. If you need legal advice, please consult a qualified family solicitor.
Sideby works best when both parents participate, but some features are useful on their own. You can track handovers, log expenses, and maintain your own records regardless. If you're in proceedings, having one-sided records is better than none—and they may encourage the other parent to engage with a neutral system.
We're onboarding early users in waves. Waitlist members get invited first, with founding-member pricing. Sign up to secure your spot.
We store only what's necessary: your account details, requests, handover records, and financial logs. We don't sell your data, don't share it with advertisers, and don't use it to train AI models. Data is encrypted in transit and at rest. You can export or delete your data at any time.
Sideby is initially focused on England & Wales, with terminology and guidance aligned to that legal context. While the core features could work elsewhere, we're starting with a UK focus to ensure the product genuinely fits local needs before expanding.
Most co-parenting apps are messaging apps with a calendar. Sideby has no messaging at all. We focus on parallel parenting—where parents operate independently and communication is minimised. If your situation is high-conflict, or you've been told to reduce direct contact, Sideby is built for you.
We're still finalising pricing. Our goal is to make Sideby accessible while sustainable. Waitlist members will receive founding-member pricing. We're exploring options including a free tier for core features.
Sideby reduces surface area for conflict because there's no free-text channel. Everything is structured with clear outcomes. You can also use it solo for handover and money records — having your own factual record is valuable regardless of whether the other parent participates.
No. Sideby is designed to help prevent escalation and keep logistics clean whether you're pre-order, post-order, or neither. It's a practical tool for anyone who needs structured parallel parenting.
