For Birth Doulas

A contraction timer for doulas is one where the client does the timing and the doula sees the result as it happens. Your client opens a link on her phone and taps at the start and end of each contraction. On your phone you see each one arrive: how long it lasted, how far from the last, and whether the pattern over the past hour is tightening or drifting apart. She downloads nothing and creates no account. That is what BirthLink does, and this page explains how it works, what you actually see, where it fits in a doula’s night, and what it costs.
I built it because I am a doula, and for years my early-labor evenings looked like everyone else’s: a screenshot at 11:40, a voice note at 12:15, “they’re about six minutes apart I think,” and me trying to work out from three fragments whether to get dressed. I have lost count of the nights that went like this. Her partner sends a photo of an app screen, I zoom in to read the numbers, I ask when the last one was, and by the time he answers there has been another one. Nobody is doing anything wrong. The tool just was not built for two people.
Almost every contraction app is built for one person: the woman in labor. It does its job well. It times, it averages, it tells her when she hits five-one-one. Then it stops, because it has no idea that someone else is waiting for that information.
So the information travels the only way it can. She screenshots the app and sends it to you. Or her partner reads numbers out over the phone. Or she types “getting stronger” and you have to decide what that means.
Three things go wrong with that, and every doula has felt all of them.
First, a screenshot is a moment, not a pattern. Five contractions at 12:10 tell you what happened at 12:10. They do not tell you whether the next five are closer together, and closer together is the whole question. I wrote a separate piece on this: why doulas need more than contraction screenshots.
Second, every update costs her something. A woman in latent labor who has to report to you every twenty minutes cannot rest, and her partner spends the night being a secretary instead of holding her.
Third, the gaps are where the doubt lives. Between one message and the next, you are guessing. Guessing is tiring, and it leads to the two mistakes doulas make in early labor: arriving hours too early, or arriving late.
The idea is simple: one timer, two screens.
You send a link. From your BirthLink dashboard you create a private link for each client. It works only for her.
She opens it and times. In her phone's browser, not an app. Tap once when a contraction starts, once when it ends. If she mistimed one, she can fix it; if she forgot one, she can add it.
You see it live. Each contraction appears on your phone as she records it: duration, interval, the recent trend, and a count for the hour.
You can also be notified. BirthLink can tell you when she starts timing, when she stops, when she starts again, and when her waters break. Notifications are one more way to know, not a replacement for staying in touch: they depend on her phone and yours, so agree with her before labor how you will reach each other.
You can time for her. When she is deep in it and tapping is the last thing she wants, you can run the timer from your side while you are on the phone with her, or once you arrive. Kira, a doula in Indiana, asked for this at a home birth. Once she arrived, she wanted to keep timing herself, so the family could stop watching the clock and she would have the pattern in front of her when it was time to call the midwife. In her words: “I don't want her or her husband to worry about timing, so it's been super nice to be able to time for them.”
There are also a few small things that turn out to matter at 3 a.m. She can tell you her waters broke with one tap, from the same screen, and the time is recorded. You can send her a short line that shows up on her timer, “I’m on my way” or “try the shower and let’s see what happens.” And when she decides to stop timing for a while, she can tell you with one tap, so a quiet timer is not a mystery.
On your screen, for each client:

That is the same set of numbers you would otherwise be assembling from screenshots, except it updates by itself and it shows the direction of travel. Whether contractions are getting longer, stronger and closer together is a question the pattern answers and a single message never can.
What it does not do is interpret. BirthLink does not tell anyone when to go to the hospital. That conversation stays where it belongs, between your client and her care provider, and you support that plan the way you always have.
Early labor at home. This is the main use. Hours of contractions before it is time to join her. You follow the pattern from your own bed, she rests between contractions, and you call when something changes rather than on a schedule.
Virtual support. If you support clients in another city, or offer early-labor support remotely as a package, this is the piece that makes it real rather than a phone call every hour. There is a full guide here: how to offer virtual doula support in early labor.
On the way, or at another birth. You are finishing one birth while a second client’s contractions start. You can see both, and you can tell your backup exactly where things stand instead of forwarding screenshots.

In the room, with intermittent monitoring. Sometimes the timer is simply the cleanest way to keep a record while you keep your hands free.
These are from doulas who used BirthLink at real births. There are more on the testimonials page.
“During early labor, seeing both the frequency and duration of the contractions helps me understand whether labor is becoming established and whether there is still time before we need to leave for the hospital.”
“It helped me understand the laboring person's contraction pattern, and to know even in the middle of the night whether contractions were continuing or had stopped.”
“I have been loving being able to have a live view of my clients' contractions rather than having to wait on screenshots.”

The middle column is a real option and I am not going to pretend otherwise. If a client already loves an app with a share link and you only need a view of one birth, use it. BirthLink is for the doula who does this every month and wants one place, her own notifications, and the ability to step in and time.
Your first five clients are free, with no credit card. After that, BirthLink Live is $15 a month, or $150 a year, for unlimited clients, and you can cancel any time. If you attend only a few births a year, you can instead pay $10 per birth with no subscription.
Your client never pays and never installs anything. I ask doulas to present it to her the way I do: as something you are giving her, not something she has to set up.
No. She opens the private link you send in her phone's browser and times there. Saving it to her home screen is optional.
Yes. Every contraction she records appears on your phone as it happens, with its duration, the interval, and the recent pattern. You can also be notified when she starts, stops or restarts timing.
Yes. You can start and stop contractions from her live view on your phone when she is too far into labor to tap, or when you are with her and want to keep the record yourself.
Yes. It runs in the browser, so your client installs nothing. On an iPhone, adding BirthLink to your own home screen makes your notifications more reliable.
Yes. Each client has her own link and her own view on your dashboard. Unlimited clients are included in the monthly price.
Yes. Every contraction she records is saved, and her live view keeps showing the latest session after she stops timing.
No. It times contractions and shares them between a client and her doula. It does not interpret them and does not give medical advice. Decisions about when to call a provider or go in stay with your client and her care team.
It includes one. Your client uses the timer from the link you send. The difference is that you see what she times, live, and can time for her when needed.
The timer your client uses is described on the timer page.
