One quick question: what do you most want help with?
Thank you.
Rest window.
Low and slow,
on purpose.
Aava comes from "aava meri," Finnish for "wide open ocean."No current to fight against.A calm, open sea to move freely in.
women have pushed through cycle symptoms at work or school.
a year spent about a third less productive.
Schoep et al., BMJ Open, 2019 (32,748 women).
Pushing through every day isn’t a strategy.
Knowing when to push is.
Your daily rhythm of sleep, light, and energy.
Your monthly rhythm, give or take.
Only 13% of cycles are exactly 28 days.
Bull et al., npj Digital Medicine, 2019 (600,000+ cycles).
Most plans follow one.Aava follows both.
Each phase of your cycle can feel different.
Aava helps you work with it instead of against it.
Energy and confidence often climb. A good time to start what you’ve been putting off.
Outward energy often peaks. Pitch, connect, and be seen.
Turn inward. Edit, wrap up, and guard your energy.
Energy often dips. Do less, recover more, and let your body lead.
Aava estimates ovulation as 14 days before the next period, and counts summer as that day and two days either side. Longer or shorter cycles mostly change the length of spring. Actual timing varies between cycles and between people.
Lenton et al., Br J Obstet Gynaecol, 1984 · Bull et al., npj Digital Medicine, 2019.
Phases are estimates from your dates, not medical advice or birth control.
Knowing your season is the start.Living it is the point, with small daily habits across the parts of your life that matter.
You choose up to five plays per pillar. Mark them done, and each season shows how you’re doing.
Aava turns your rhythm into daily habits for every part of your life.
Block your morning for focused work.

Build momentum
Energy tends to rise.
Start what you’ve been putting off.
Looking back, we fill the gaps with how we think we usually feel. A check-in each day captures the day you actually had, so Aava learns from real days, not assumptions.
Across 138 studies, tracking progress helped people reach their goals, especially when they wrote it down. Every play you mark done counts.
People are more likely to go after a goal at a new beginning, like a new week or a new month. Your cycle gives you four each month. Aava plans each season fresh, so a slow week never follows you into the next.

For women who won’t trade balance for growth.
Plays for the pitch, the heavy session, and the hard conversation, timed to when you feel ready.
Regular or not, your daily check-in leads. The harder your cycle is to predict, the more Aava goes by how you feel.
Every check-in teaches Aava a little more about you, measured against your own baseline, not an average. And it’s all stored on your phone and in your own iCloud.
Aava is built by a software engineer who designs for security first. Privacy isn’t a setting added later. It’s how the app is built.
Your cycle, check-ins, birthday, and every answer in Settings live on your iPhone, with a copy in your own iCloud. We can’t see them.
All we hold is your sign-in email and account basics: your plan, invites and AI choice. None of it is health data. It never goes to AI or into our security logs.
Only with your yes. AI sees just what shapes your guide and your answers, nothing more. Never your name, birthday, or exact dates, and it keeps none of it.
I spent years as a software engineer in the Bay Area, trying to keep up with routines built for a body that’s the same every day. Mine isn’t. And many women’s bodies aren’t, either.
Then came breast cancer and corporate burnout. Both taught me to listen to my body instead of fighting it.
Aava is the support I wish I’d had. I built it so you never have to choose between your wellbeing and your ambitions.

No. Aava offers everyday guidance based on your cycle and daily check-ins. It is not a medical device and doesn't diagnose or treat any condition.
Aava doesn’t stop at tracking your cycle. It uses your rhythm to help you act across every part of your life, one day and one season at a time.
Only with your yes. AI shapes your daily guide and answers your questions from your cycle, check-ins and what you tell Aava. It never sees your name, email, birthday, or exact dates, and keeps none of it. The full details are in our privacy policy.
Your daily check-in leads. If today doesn't match what the phase predicts, Aava goes with how you feel. The less predictable your cycle, the more your check-in counts.
Aava still works. When there’s no cycle to place, your daily check-in leads your guide.
Everything you tell Aava stays on your iPhone, with a copy in your own iCloud. Sign in to the same Apple Account on the new iPhone, then to Aava with the same email, and your records are back. Step by step on our support page. We can't see your iCloud copy.
