There are hundreds of pregnancy apps.
Almost all of them are built around the same assumption: the person downloading is the one who is pregnant.
That makes sense for most use cases, but it leaves partners navigating content that was not really written for them.
A handful of apps have tried to address that. Some are built for dads from the start. Others are strong general pregnancy references with enough depth to be useful for partners.
A few are post-birth tools worth having ready before the due date arrives. Here is what is actually worth downloading in 2026.
Nine Months
Nine Months is built specifically for the partner. The whole app is organised around a single question most dads find themselves unable to answer confidently: how far along are we, exactly?
Enter your due date once, and the app shows you the current week, day, and trimester every time you open it.
There is a lock screen and home screen widget so you can check at a glance without even unlocking your phone.
No account required, no subscription, no data sharing.
It is not trying to be a comprehensive pregnancy reference. It is trying to make sure you always know where you are in the pregnancy, which turns out to be more useful than it sounds across nine months.
Platform: iOS
Cost: $4.99, one-time purchase
Daddy Up
Daddy Up is another app built with the partner in mind from the start.
It includes weekly pregnancy progress, a customisable checklist, a journal, and size comparisons calibrated toward the kinds of analogies dads tend to find more relatable.
If you want a more rounded experience beyond knowing the week, this adds a layer of tracking and reflection to the pregnancy.
Platform: iOS
Cost: Free
What to Expect
What to Expect has been the standard pregnancy reference for decades, and the app reflects that.
Week-by-week development updates, symptom context, a contraction counter, and enough clinical depth to make sense of what your partner’s appointments are actually checking.
It is designed primarily for the pregnant person, but partners who want to understand what is happening medically rather than just when the next milestone is will find it useful.
When your partner mentions something from a prenatal appointment and you want to understand it without asking her to explain it again, this is a good place to look.

BabyCenter
BabyCenter earns its place here less for the pregnancy content, which is solid but similar to What to Expect, and more for what happens after the birth.
It transitions naturally into the first year, so you do not have to switch to a different set of tools once the baby arrives.
If you want continuity across the full journey from conception to the first birthday, it is worth setting up early.

Ovia Pregnancy
Ovia goes deeper on the clinical side than most pregnancy apps, covering development, symptoms, nutrition, and sleep.
The shared access feature also works better than most: partners can follow the pregnancy with their own view rather than being a secondary user on someone else’s account.
If you and your partner want a single place to log and review how things are going together, Ovia handles that more thoughtfully than the alternatives.

Why do partners need a pregnancy app?
The default setup during pregnancy is that the pregnant person becomes the information hub.
They read the books, attend the appointments, track the weeks. The partner stays informed through them.
That works up to a point, but it puts one person in charge of keeping the other updated, which gets tiring, and it means the partner’s understanding of the pregnancy is always one step removed.
An app gives partners their own direct connection to the timeline.
You are not waiting to be told what week it is. You are not asking your partner to recap the appointment. You have the information yourself, and you can come to conversations about the pregnancy already oriented rather than starting from zero.
For some couples that shift is small. For others it makes a noticeable difference to how engaged the partner feels, particularly in the first trimester when the pregnancy is not yet visible and there is not much to anchor to beyond knowing the due date.
Tips for partners during pregnancy
Being present during pregnancy does not require a lot. It mostly requires consistency over nine months, which is harder than it sounds.
Stay current on the week. Knowing you are at week 28 rather than “around seven months” lets you follow conversations at prenatal appointments, understand what milestones are coming, and have more useful discussions with your partner about what is ahead. It signals genuine engagement, which matters.
Learn what each trimester actually involves. The first trimester is often the most physically difficult, despite being the least visible. Fatigue and nausea can be significant, and a lot of partners underestimate it because nothing looks different from the outside. Understanding what is typical in each phase means you can be more useful and less surprised.
Protect the scan appointments. The 12-week dating scan and the 20-week anatomy scan are the two appointments where your presence as a partner matters most. If you can only take time off for two appointments across the whole pregnancy, make it those two.
Ask rather than assume. What your partner needs from you will shift week to week. Checking in with a direct question is more useful than making fixed assumptions based on how things were a month ago.
Frequently asked questions
What is the best pregnancy app for dads?
Nine Months is the most focused tool for partners who want to always know exactly where the pregnancy stands. It shows the current week, day, and trimester at a glance without any calculation. For broader pregnancy information covering development, symptoms, and health context, What to Expect and Ovia are the strongest all-round options.
Are there pregnancy apps designed specifically for dads?
A few, yes. Nine Months and Daddy Up are both built with the partner as the primary user rather than as an add-on. Most other major pregnancy apps (What to Expect, BabyCenter, Ovia) are designed for the pregnant person first but include partner modes or shared access.
When should a partner download a pregnancy app?
As soon as you know the due date. The first trimester is the period when partners tend to feel most disconnected from the pregnancy, partly because nothing is visible yet and partly because the pregnancy often has not been announced. Having a way to track it yourself from the beginning helps with that sense of being out of the loop.
Do pregnancy apps share your data?
It varies. Most apps that require account creation use some data for personalisation or analytics. Nine Months requires no account and no data sharing. If privacy matters to you, check the app’s privacy policy and what permissions it requests on installation before signing up.
What if my partner already has a pregnancy app?
You do not need to use the same one. Many couples find it useful to track the pregnancy separately. Your partner’s app might be a detailed symptom log and health diary. Yours can be a clean reference for the week and trimester. They serve different purposes and there is no reason they have to overlap.
If you are looking for a simple way to stay on top of the pregnancy without the noise, Nine Months is a good place to start.
