The decision everyone underrates
Most people believe living together first makes a marriage more likely to work. The research points the other way: couples who move in before they've clearly decided where things are headed tend to face rockier odds, not because moving in is wrong, but because so much goes unspoken.
The couples who have a smooth transition aren't the ones who agree on everything. They're the ones who talked about it. That's what Tandemly is for.
The pattern comes from decades of research on cohabitation by Stanley, Rhoades & Markman — the researchers who coined “sliding vs. deciding.”

Questions
Frequently asked questions
What is Tandemly?
Tandemly is a relationship assessment for couples approaching a big step, especially moving in together for the first time. It helps you find where you already align and surfaces the conversations worth having to prepare you for success.
Why moving in together specifically?
Moving in is often treated as a logistics decision, but it's one of the more consequential moments in a relationship, and one couples rarely prepare for the way they'd prepare for marriage. Tandemly is built for exactly that gap.
How does it work?
Each partner answers 28 questions across 7 core relationship areas, separately and privately. Once you're both done, your answers merge into a shared alignment map.
Do we need a counselor or account?
No, and it's completely free right now. Tandemly takes about 10 minutes per person, no account and no cost.
Will my partner see my answers before I finish?
No. Nothing is shared until both partners complete the assessment, so your answers can't influence each other.
What topics does it cover?
Money & finances, kids & family planning, home & daily life, career & ambition, connection & intimacy, conflict & repair, and values & future vision.
