elara vs
flo.
Flo is a cycle-first health app with a pregnancy mode and a huge content library; Elara is a pregnancy-only tracker built around partner mode. If you want one app for cycles, fertility and pregnancy, Flo is the safer bet. If pregnancy is the whole point and you want your partner genuinely involved — with his own live view, weekly tips and tasks — Elara was built for exactly that.
what flo does well.
Flo is one of the most established women’s health apps in the world. Its cycle and ovulation tracking is excellent, it carries an enormous library of medically reviewed articles, and its pregnancy mode grew out of years of period-tracking data. It also offers “Flo for Partners”, which shares summaries of what she’s experiencing with a partner’s phone.
If you used Flo to conceive, staying in it for pregnancy is genuinely convenient — your history is already there, and the app switches modes without losing anything.
where elara differs.
Elara does one thing: pregnancy, for two people. There is no cycle mode and no mode switch — the entire app is the forty weeks. Partner mode is the core feature rather than an add-on: your partner joins with a rotating six-digit code and sees the week, the baby illustration and size, milestones and the next appointment live on his own iPhone, gets weekly tips written for him, and can send reactions you feel as a buzz.
The privacy model is also different by design. In Elara, your journal, photos, moods and symptom logs never leave your device — there is no server copy and no setting that could create one. Flo stores health data on its servers to power its features (it also offers an anonymous mode); which trade-off you prefer is a personal call, but the models are not the same.

the verdict.
choose flo if
you want a single app across your whole reproductive life — cycles, conception, pregnancy, postpartum — with a deep content library, or you need Android. Flo has been doing this for years and does it well.
choose elara if
pregnancy is the season you're in, you want your partner to see the same week and baby you do — live, with his own tips and tasks — and you want the private parts (journal, photos, moods) to stay on your phone rather than a server.
common questions.
Can partners use Flo together during pregnancy?
Yes — Flo offers “Flo for Partners”, which shares summaries of her cycle or pregnancy with a partner’s phone. It is a companion view rather than a shared timeline. Elara links two phones to the same live pregnancy: he sees the week, baby size and milestones in real time, and gets his own weekly tips and tasks.
Is Elara a replacement for Flo?
Only for pregnancy. Elara does not track cycles or fertility, so if you rely on Flo for ovulation tracking it still earns its place before and after pregnancy. Some couples use both: Flo for cycles, Elara for the forty weeks together.
Which app is more private?
They take different approaches. Elara keeps journal entries, photos, moods and symptom logs on your device only — there is no server copy. Flo stores health data on its servers to power its features and offers an anonymous mode that decouples data from your identity. If “never uploaded” is your bar, that is Elara’s model.
