Pregnancy app for husbands: an honest comparison.

▸The short version

• He wants a dedicated dad app on an iPhone: Daddy Up or The Big Daddy.
• He is on Android: Daddy Up is on Google Play. The Big Daddy says it is iOS only.
• You want to invite him into your own tracker: Pregnancy+ says a partner can follow the baby's development from their phone.
• You want one app for you that carries on after the birth: What to Expect or BabyCenter, both with baby trackers.
• He will not install anything: DAD-OS runs in his phone browser, and you can send him a link.

▸Side by side

Prices are from the US App Store listing on the day we checked and may differ in the UK. Partner features are what each listing or website says. Where it says nothing, we say so rather than guess.

▸What each one does better than DAD-OS

What to Expect: one app from pregnancy into the baby years, with logs for symptoms, weight and kick counts, a baby log for feeds, nappies and sleep after the birth, and a parent community. Its size comparisons come in themes that include sports. [App Store]

BabyCenter: free childbirth and baby safety classes, a Birth Club community by due month, a kick counter, a contraction timer, a printable hospital bag checklist and a baby growth tracker after the birth. [App Store · Google Play]

Pregnancy+: interactive 3D models of the baby's development, a hospital bag list that covers the birth partner, and the option for a partner to follow along on their own phone. [App Store · Google Play]

Daddy Up: a native app on both iPhone and Android, written for dads with its own outdoors humour, with a journal, checklists for each trimester and a contraction timer. [App Store · Google Play]

The Big Daddy: it asks for no email address and keeps everything on the phone. Its listing says it was created by a dad who is a medical doctor and offers doctor-reviewed articles, and premium adds a contraction timer, checklists and a weekly bump photo timelapse. [App Store · thebigdaddyapp.com]

▸Where DAD-OS is different

It talks to him. Every week of pregnancy is written for the dad: what is happening to her, what the baby is doing, his jobs that week, and the things not to say. Baby sizes are sports equipment, never fruit.

The Decoder covers the tense moments: what is likely going on, three steps, and the one sentence that makes it worse.

It is built for you to send. The pages for partners explain pregnancy to him, each with a Send to him button, and the UK paternity leave and US FMLA calculators turn your due date into his deadlines, free and with no login.

The honest limits: there is no app to install from a store, no linked partner account, and it does not track your symptoms. If you want those, pair it with one of the apps above. Signing in saves his progress.

▸For you: how to get him to actually use it

Do not send him an app and a lecture. Send one link at the right moment: his week of pregnancy on a Sunday night, the decoder page after a rough day, or his leave deadline when you get the due date. One useful page beats a download he never opens.
