Your wearable knows your body.
Bloom knows you're pregnant.

“Is this normal?”
why is my resting heart rate 15 bpm higher pregnant
HRV dropping second trimester should I worry
wearable says poor recovery every day pregnancy
Your wearable keeps scoring you as if nothing changed. But everything changed — blood volume climbs by almost half, resting heart rate rises 15–20 bpm, HRV shifts by design. The data isn't wrong. It's missing the context that makes it mean anything: you're pregnant, and this is your body doing exactly what it's built to do. Bloom exists to supply that context.
How it works
Your data. Your baseline.
Pregnancy context.
Connect Apple Health.
Two minutes. Bloom reads what your devices already write — Apple Watch, Oura, Garmin, and most wearables that sync to Apple Health. No new hardware, no manual entry.
Bloom learns your baseline.
Your own pre-pregnancy history becomes the reference point — not a population chart, not an average of other women. You, before. You, now.
Context, every week.
Pregnancy-adjusted ranges and a plain-language read on each trend, evolving trimester by trimester as your physiology does.
Your resting heart rate is within your adjusted range for week 33. Calculated from your pre-pregnancy baseline and current trimester.
· Calculated from your pre-pregnancy baseline and current trimester
Also in the Health tab: HRV, sleep, activity, and weight — each with its own adjusted range and 7-day trend.
Why your baseline matters
Same number.
Different stories.
Week 30 · resting heart rate
82
+20 from her baseline
Her baseline was 62. She's climbed twenty beats — the textbook mid-pregnancy rise, right on schedule.
Week 30 · resting heart rate
82
+4 from her baseline
Her baseline was 78. She's barely moved — a different trajectory, and a different conversation to have.
Two women. Same week, same 82. A population chart treats them identically — their own baselines tell two different stories. That's why Bloom measures you against you.
Wearable platforms added pregnancy modes.
Bloom started with pregnancy.
WHOOP and Oura now offer pregnancy features — genuinely useful ones, if you own their hardware and pay their subscription. Bloom takes the opposite path: a pregnancy product first, built to work with the devices you already wear, through Apple Health.
And because pregnancy is the whole product — not a mode — Bloom carries what a recovery platform doesn't: symptom and kick tracking, prenatal vitamins, week-by-week development, and a report designed for your OB's desk.
The weeks in between
Your next appointment is two weeks away.
Your body isn't waiting.
For most of pregnancy, prenatal visits are weeks apart — and most of pregnancy happens between them. Bloom keeps a quiet, continuous picture of those weeks, so instead of carrying a list of 2 a.m. worries into your next visit, you walk in with observations: here's what shifted, here's when it started, here's what I want to ask.
Not a diagnosis. Preparation.
For your care team
Walk in with
the whole picture.
One tap builds a clean PDF of your pregnancy — heart rate, HRV, sleep and weight trends, symptoms, kick sessions, vitamins — organized the way a clinician actually reads. Hand it to your OB, midwife, or doula and spend the appointment on answers instead of recall.
Bloom organizes your wellness data. Your care team makes the calls — exactly as it should be.

Every insight in Bloom passes clinical review by a practicing OB-GYN and Maternal Fetal Medicine specialist before you see it — grounded in ACOG guidelines and peer-reviewed literature, not scraped from generic health databases.
And Bloom stays in its lane: it helps you understand your own trends. It doesn't diagnose, prescribe, or stand in for the people who take care of you.
Privacy
Your pregnancy is not
an advertising category.
Bloom is subscription-supported — you're the customer, not the product. The details are in our privacy policy, written to be read.
I was eight weeks pregnant, watching my heart rate trend high on my wearable every day. I asked my OB. She said it was completely normal — your heart rate climbs to support the extra blood volume your body is building. The app had no idea I was pregnant. I built Bloom because that gap shouldn't exist.

Questions
Fair questions,
straight answers.
Do I need a wearable to use Bloom?
No. Symptom tracking, kick counting, prenatal vitamins, weight, and the full week-by-week program work with nothing but your phone. The Health tab — pregnancy context for heart rate, HRV, sleep, and activity — comes alive when Bloom can read data from a wearable through Apple Health.
Which devices work with Bloom?
Anything that writes to Apple Health: Apple Watch, Oura, Garmin, and most wearables that sync with Apple Health. If your device's data shows up in the Apple Health app, Bloom can read it — there's no Bloom-branded hardware to buy.
Is Bloom giving me medical advice?
No. Bloom is a wellness product: it organizes your own data and shows how it's trending against your own history, with educational content reviewed by a board-certified OB-GYN and Maternal Fetal Medicine specialist. It doesn't diagnose, treat, or tell you everything is medically fine — that's your care team's job, and Bloom is built to make those conversations better, not replace them.
What does Bloom cost?
$79.99 a year (about $6.67 a month) or $12.99 month-to-month, after a 1-week free trial. The first 100 users get their first year free with code FOUNDINGMOM — redeem it in the App Store after you download. Subscriptions run through the App Store and can be cancelled there anytime.
What happens to my health data?
The Bloom app has no ads and no third-party ad trackers, and your health data is never used for advertising. Any sharing is opt-in and de-identified — off until you turn it on. Bloom is subscription-supported — you are the customer, not the product. You can delete your account and data from inside the app. The full details live in our privacy policy.
I'm already 20 weeks in. Is it too late to start?
No — Bloom reads your existing history from Apple Health, so your baseline and trends are built from data you've already collected, even if you install Bloom in your third trimester. The weekly program picks up wherever you are.
Is Bloom on Android?
Not yet — Bloom is iOS-first because it's built on Apple Health. If you're on Android, email support@bloomformoms.com and tell us; it directly shapes what we build next.
