What Tandem adds
Built around your agreement
Upload the parenting plan once: Tandem reads the schedule, holidays and splits, and expense requests quote the exact clause that applies.
One price, both parents
One subscription covers both parents, from $9.99 a month on a yearly plan.
Swaps and make-up time
Trade days with make-up time offered; the calendar updates for both parents when it's accepted.
Travel consent, border-ready
Your co-parent reads and e-signs the letter in the app, the signed PDF is filed in your travel folder, and every letter is saved on your phone for the airport. Signing steps for every province and state, in English or French.
Blended families
Several families on one account, each kept separate. Partners, caregivers, teens and professionals see only what they should, and partners see the kids' details only with the other parent's agreement.
A calendar the kids can read
A printable, kid-friendly calendar of which home, switch days, holidays and trips, with nothing about money, messages or court.
Reminders from your agreement
Yearly deadlines and items that rotate between odd and even years reach the right parent ahead of time, and each one is logged when it's done.
Child support log
The paying parent records each payment and the other confirms it, so the balance is agreed.
Calm, documented messaging
Timestamped messages with first-viewed times, calmer rewrites and translation.
