Pregnancy,
together.
One curated brief a week. How mom and baby are doing, and what you can actually do about it. Plus Nolan, for the questions you have at 2am.


One signal, not a feed.
Every week, Tandem sends a single brief. What is happening with mom and baby, and what you can do about it. Read it in two minutes, then put your phone down.
- Mom and baby
- What changed this week, in plain words. No jargon, no charts to decode.
- For Dad
- Two or three concrete things you can do. Small, useful, never homework.
- Forty weeks
- One brief at a time, from the first line to the day you meet them.
The size of a lime, and learning to move.
Reflexes are kicking in. She may feel less queasy.
Book the scan. Take one thing off her plate.
The anatomy scan is a few weeks out.
A question, not a search.
Nolan is part of Tandem. Ask him anything about the pregnancy, set a reminder, or check what is on the calendar. He answers in a sentence, not a lecture. And he never nags.
Part of Tandem
What should I ask at the 12 week scan?
Ask about the due-date estimate and whether everything looks on track. Want me to add the next appointment to your calendar?
Forty weeks, one at a time.
A new illustration and a new brief for every week. From the first flutter to the day you meet them.
Your pregnancy stays on your phone.
Tandem is local-first. The things you tell it stay with you, and the only thing that ever leaves your phone is a question you choose to ask.
On your device
Your due date, names, notes, and every brief are stored locally. Not on our servers.
Only your questions
When you ask Nolan something, only that question goes out to answer it. Nothing else.
No tracking
No ad networks, no analytics selling your data. There is nothing to sell.
Good to know.
Who is Tandem for?
First-time dads, partners, and co-parents who want to be useful without reading a textbook. If your partner is expecting, it is for you.
Is it free?
The weekly brief is free. Nolan, the assistant who answers questions and handles reminders, is a subscription.
Do I need an iPhone?
Tandem is iPhone-first at launch. Android may follow.
Is my data really private?
Yes. Tandem stores your information on your device. The only thing that leaves is a question you choose to ask Nolan. See the privacy policy for the details.
