Cycle-aware training log

See how your strength shifts with your cycle, phase by phase.

Log a session in a few taps: lifts, runs, yoga, whatever you actually do. Every session is tagged with your cycle phase automatically, so after a few cycles you can see which weeks are usually hard, instead of guessing.

  • Menstrual
  • Follicular
  • Ovulatory
  • Luteal

Your four phases, in plain language.

New to cycle syncing? Here is the gentle version. These are what many people tend to feel, not rules for your body.

Menstrual

Recharge

Energy is often low. Gentle movement or a full rest day are both completely valid.

Follicular

Building back up

Energy tends to climb. A common time to build a little, if you feel up to it.

Ovulatory

Peak for many

Often the strongest few days of the cycle, though everyone is different.

Luteal

Winding down

Energy can dip. Steady, kinder sessions often feel best here.

Lunia won't tell you to "train heavy today." It logs your real sessions and shows how your body actually moves through each phase, so you plan around your own pattern. Rest days included, no guilt.

No extra logging. Just your own patterns.

Three steps, and only the first one is any work. Lunia handles the rest in the background.

Logging a session in Lunia
  1. 01

    Log your training

    Sets, reps, weight, runs, rides, swims: whatever you actually do, with a rest timer and personal records built in.

  2. 02

    We tag it with your phase

    Every session is quietly marked with your cycle phase. Nothing extra to fill in, Lunia already knows where you are.

  3. 03

    See your own patterns

    After a few cycles, watch how your strength, volume, and energy really move by phase, with honest error bars.

The honest part

Your data, with the error bars left in.

Most cycle apps hand you a hormone theory. Lunia plots what your own lifts actually did, phase by phase, and shows how sure it is. When the range still touches your baseline, it says so.

Follicular Clear pattern

Ovulatory Clear pattern
+3.1%
Luteal Keep logging

Menstrual Keep logging

Simple to log. Quietly powerful underneath.

Most of what you see is free forever, with the deeper interpretation reserved for Pro. Whether it's your first week or your hundredth, Lunia stays quick to log and quietly gets sharper as your history grows.

One is a claim. The other is your data.

Most cycle apps tell you what a generic hormone theory says you should do. Lunia shows you what your body actually did.

Honesty is the brand. When your data doesn't show a clear pattern, Lunia says so: "no clear effect yet, keep logging." It never manufactures a signal.

We don't sell your data. We don't even see it.

Lunia shows how your own logged workouts relate to your own cycle. Your data lives on your device first, never sold and never handed to data brokers.

Local mode

Use Lunia with no account at all. Your training and cycle data never leaves your device.

Encrypted before it uploads

Cloud backup is encrypted on your phone with AES-256-GCM. The key never leaves your device, so we cannot read it.

No trackers, no ad SDKs

No cross-app tracking, and no analytics on your cycle or training data. Ever.

Yours to take or delete

Export everything, or delete your account, anytime from Profile, Data and privacy.

Free forever. Pro if you want the depth.

Logging is never gated. Lunia Pro only unlocks interpretation: the patterns, the report, and the export. Capturing your own data is always free.

Questions, answered honestly.

Everything about how Lunia works, what's free, and how your data stays yours.

Is Lunia a medical or hormone-advice app?

No. Lunia is not a medical device and makes no hormonal or medical claim. It doesn't diagnose or treat anything, it shows patterns in your own logged numbers. When there's no clear pattern yet, it says so instead of guessing.

I'm new to training. Is Lunia for me?

Yes. Lunia is built to be gentle for beginners: log a session in a few taps, follow a simple suggested session when you want direction, and there is no pressure to chase numbers. It quietly learns your patterns as you go, no experience needed.

Do I need an account to use it?

No. You can set up Lunia without an account and every free feature works fully in local mode, with none of your training or cycle data sent anywhere. Signing in with Apple or Google is only needed if you want encrypted cloud backup.

Does Lunia sync with Apple Health?

Yes. Lunia reads your runs, rides, swims, rows, and walks from Apple Health and your Apple Watch so you don't have to log them twice. It's read-only: Lunia never writes anything back to Health.

What if my cycle is irregular, or I'm on birth control?

Lunia's phase ring is sized to your own logged cycle length, not a fixed 28-day model, so irregular cycles are fine. If you're on hormonal birth control or don't get a regular period, logging and training work exactly the same; Cycle Patterns just needs enough natural-cycle data to find anything, and it will say honestly when there isn't.

Which devices does Lunia run on?

Lunia runs on iPhone and Android. Apple Health and Apple Watch auto-import are iOS-only for now; everything else works the same on both platforms.

What does Lunia Pro add over the free plan?

Logging is never gated: all 10 activities, unlimited sessions, personal records, and cloud backup are free forever. Pro adds interpretation, like the Cycle Patterns forest plot, the full monthly Cycle Report, shareable pattern cards, advanced metrics, and CSV or PDF export.

What happens to my data if I cancel Pro?

Nothing is ever deleted. Everything you logged stays yours: on the free plan you can always see and export your last 90 days, and your older history is kept safe, ready to unlock again if you resubscribe. Lunia never holds your own data hostage.

Is my period and training data private?

Yes. Your data lives on your device first. If you turn on cloud backup, it's encrypted on your device with AES-256-GCM before it ever leaves; the key never leaves your phone, so we can't read it. We never sell data or use it for ads.
