The 30-second summary
Lively takes a cycle-syncing approach. It tailors nutrition, workouts, and mood advice to each phase of her cycle, all designed for the person living it. It also has a partner-syncing feature: she shares her current phase and energy, and you can send a "thinking of you" nudge. That is more than most apps offer.
But the partner side is a window into her app, not a tool of your own. There is no home screen built for you, no daily guidance written for your role, and no Watch or Lock Screen widget on your side. Yuni starts from the opposite end. You are the primary user, and every screen answers one question: what do you do today.

When Lively is the right choice
If she wants cycle syncing for herself, eating and training with her phases instead of against them, Lively is a strong pick. The partner view is a thoughtful extra, and if she likes keeping everything in one app, sharing her phase with you from inside Lively is simple.
The limit shows up on your side. Lively's partner feature gives you her phase and a nudge button. It does not tell you what that phase means for how you behave, and you have to open her app and navigate to find it.
When Yuni is the right choice
If you want an app that is yours, that opens straight to today's mode and what to do, Yuni is for you. You do not borrow a corner of her account. You glance at your own home screen or your Watch and you know how to show up.
No account is a deliberate choice. Partners download a support app quietly, so Yuni asks for nothing. When you pair, her data stays on her phone and your guidance stays on yours. Nothing central means nothing to breach.
Yuni also writes the guidance partners search for at 11pm. "What not to say to her on her period." "The 20-minute pre-period conflict protocol." Lively, focused on her cycle syncing, doesn't write for that audience.
The simple verdict
Get Lively if…
She wants cycle syncing for her own nutrition, mood, and fitness, and a light partner view is a nice bonus.
Get Yuni if…
You're the partner. You want an app of your own with daily guidance and a Watch glance. You want to stop guessing, and you don't want another account.
In practice they sit side by side: Lively on her phone, Yuni on yours. Hers syncs her cycle. Yours tells you how to help.
How they work together
If she tracks in Lively or Apple Health, you pair through Yuni's link and Yuni reads her phase from her phone, then shows you a daily nudge on yours. Her cycle data never leaves the two phones.
If she doesn't track at all, Yuni still works from a single estimated cycle date. Less precise, still useful.
Quick answers
Is Yuni a Lively competitor?
They overlap more than most, but they serve different users. Lively is for her cycle syncing. Yuni is the partner's app. Many couples run both.
Does Lively have a partner mode?
Yes, a partner-syncing view inside her app. It shows your phase and lets you send a nudge. It doesn't give you daily guidance or a widget of your own.
Do you need an Apple Watch?
No. Yuni runs on iPhone, iOS 17+. The Watch widget is optional, and Lively has no partner widget at all.
What does it cost?
Free trial. Weekly £4.99 or Annual £79.99 after that. No ads, no data sale.
One tap. No account. If it's not useful, delete it and we never know you tried.
