Cycle-aware weight tracking

Your weight isn't random. You're just missing half the picture.

Track your weight across your cycle and understand why the number moves, not just that it did.

You stepped on the scale and the number went up.

You didn't eat more. You didn't skip workouts. But the number moved anyway. And it felt like you failed.

You didn't. Your body retains water differently across your menstrual cycle. Luteal phase alone can add 1–3 kg that disappears a week later. Wavara helps you see this pattern so the number stops feeling random.

Same-Cycle-Day Comparison

Compare Day 14 this month to Day 14 last month. Not Monday to Monday.

Other apps compare Monday to Monday. Your hormones don't follow a weekly schedule. Wavara compares cycle day to cycle day, so you can see whether something actually changed, or whether it's just where you are in your month.

Last cycle · Day 14

63.2 kg

This cycle · Day 14

62.4 kg −0.8 kg

Same hormonal context. Real progress.

Who it's for

Sound familiar?

01

Weight without guilt

Track your weight without judgment. Understand why numbers fluctuate across your cycle.

02

Know the why

Log numbers, or actually understand them. See the why behind every phase.

03

Built for this

Tried other weight apps that didn't fit or felt judgmental? We built this differently.

Cycle trackers don't track weight. Weight apps don't know your cycle.

Each tool does one thing well. Wavara connects both.

Cycle Trackers

Great at

  • + Period and ovulation tracking
  • + Hormone awareness and phase education
  • + Symptom logging across the cycle

What they miss

  • − Weight trends tied to cycle phase
  • − Cycle-day weight comparison over time
  • − Context for why the scale moves each week

The bridge

Wavara

Connects both

  • Tracks weight alongside your cycle phase
  • Explains fluctuations through a hormonal lens
  • Shows patterns across multiple cycles
  • Separates real change from cyclical noise

Weight Trackers

Great at

  • + Daily weigh-in logging
  • + Long-term trend charts
  • + Progress visualisation over months

What they miss

  • − Cycle context for weight changes
  • − Why fluctuations happen each week
  • − Hormonal phase awareness

How it works

Four steps to actually understanding your weight.

Step 1

Log

Step on the scale. Open the app. Tap your weight. If you're on your period, tap that too. Done in 10 seconds.

−

Other apps ask you to log weight. That's it. A number in a void.

+

Wavara captures the context too. Your cycle day, your phase, how you're feeling. Two extra taps, and now the number actually means something.

Step 2

See

Your weight graph is colour-coded by cycle phase. That 2kg spike? It's in the luteal zone. Same thing happened last month.

−

Other apps show a jagged line. Up, down, up. No explanation. Just stress.

+

Same data, but colour-coded by menstrual phase. The spikes suddenly have a reason.

Step 3

Understand

You're on day 24. Progesterone is peaking. Water retention is normal. Last cycle you were +1.8kg at this point, and it dropped by day 4.

−

Other apps say: 'You gained 2kg this week.' Thanks. Very helpful.

+

Wavara says: 'You're in the luteal phase. Expect 1-3kg of water weight. Here's what happened at the same cycle day last month.'

Step 4

Trust

After a few cycles, you stop flinching at the number. You know what's coming and why. It just stops feeling personal.

−

Other apps leave you with a number and no context. Good week? Bad week? Who knows.

+

Cycle after cycle, the picture gets clearer. Your body has a rhythm. You just couldn't see it before.

What makes Wavara different

The features that actually matter.

Your phases, calculated from your data

Wavara learns your actual cycle length over time. Phase boundaries adapt to your body, not a generic 28-day model. Based on data from 600,000+ cycles.

Phases sized to your cycle

Your past self, talking to your future self

Notes you write show up again at the same phase next cycle. Last month's "feeling bloated, it's the luteal water retention" reappears when you hit that phase again.

Day 22, last cycle

Bloated, craving salt. Normal for luteal.

Day 22, this cycle

Same thing. At least now I know why.

Progress over time

Phase averages, consistency streaks, the small wins you miss day-to-day.

240+ tips across every phase

One tip a day to start. Tap deeper for the full guide: energy, mood, sleep, cravings.

Your data, your choice

Everything lives on your device by default. Opt in to cloud sync if you want a backup, or keep it local. Export as CSV or JSON any time.

menstrual cycles analysed

Built on research, not guesswork

A peer-reviewed study by Bull et al. (2019) in npj Digital Medicine analysed over half a million menstrual cycles to map how symptoms shift across cycle phases. That's what Wavara's personalised insights are built on.

On-device by default

All weight and cycle data stays on your phone unless you opt in to cloud sync.

Cloud sync is opt-in

Want a backup? Turn on cloud sync. Prefer everything local? That's fine too. Your call.

FAQ

Questions you might have

If yours isn't here, ask us.

Is it free? +
It'll be free when we launch. We might add a paid tier later for power users who want deep history or extra insights, but the basic tracking isn't going behind a paywall.
How is this different from Flo or Clue? +
They’re great for periods, but they ignore weight. Wavara does both. We color-code your weight graph by your cycle phase so you can see if a gain is just water retention or something else entirely.
How is this different from Happy Scale or Libra? +
Those apps are good for smoothing out trends, but they're 'cycle-blind.' A 2kg spike on day 23 is usually hormonal; on day 10, it's probably not. Wavara knows the difference.
What does 'cycle-aware' actually mean? +
The app knows if you’re menstrual, follicular, ovulatory, or luteal. Instead of just giving you a number and letting you panic, it explains why that weight makes sense for where you are in your month.
Does it work with irregular cycles? +
Totally. It doesn't force you into a 28-day model. The predictions adjust based on your actual data, whether your cycle is 25 days or 35.
Can I use it on hormonal birth control? +
You can, though phase predictions won't be as useful since the pill suppresses the natural cycle. You can still track weight and withdrawal bleeds to see your long-term trends.
How accurate are the predictions? +
They get better the more you use it. Nobody's perfectly regular, but after about 2 or 3 months, the app usually has a good enough handle on your patterns to explain those weight shifts.
What data do you collect? +
Just your email for the waitlist. Everything else stays on your phone by default. We'd love some usage data to see what's actually useful, but it's entirely opt-in. You can also choose to use cloud sync for backups, but that's up to you.
When does it launch? +
We're looking at 2026. Join the waitlist and we'll let you know as soon as it's ready.
Will it be on Android and iOS? +
Yep, both.

We launch in 2026. Get in early.
