The shift
Same routine every day — even though you aren’t the same every day
Most training and nutrition advice ignores the cycle entirely. Onda plans with it.
Training hard on the wrong day, then wondering why it didn’t land.
Knowing which days are for pushing, and which are for easing off.
PMS shows up like a surprise — every single month.
Recognizing a hormonal pattern — not a personal failing.
Big decisions and big moments scheduled at random.
Planning them for when your energy tends to run higher.
Slow progress feels like nothing is working.
Understanding why progress was never going to be a straight line.
The four phases
Same body, four different weeks.
Every cycle moves through four hormonal phases. Onda reads where you are today — and adapts the plan to it.
01 · Menstrual
Menstrual
Hormones at their lowest. Rest here is productive, not lazy.
02 · Follicular
Follicular
Energy climbs as estrogen rises. Build and begin.
03 · Ovulatory
Ovulatory
A short peak. Feel big days, plan big moments.
04 · Luteal
Luteal
Inward energy, rising appetite. Be steady — cravings are chemistry.
What you get
The actual app, in ten seconds a day
- MOVE
One workout cue
Matched to today’s phase — push weeks and recovery days are planned.
Why now → progesterone peaks; your body runs ~0.3° warmer today.
- EAT
One food cue
Iron-rich lunch, steady carbs — food that fits the week you’re in.
Why now → cravings this week are chemistry, not weakness.
- THE WHY
The reason, every time
A short, honest explanation with every cue. Not just an instruction.
Why now → knowing why makes it easier to trust the rest day.
- PRIVATE
One date. Nothing else.
Phase math happens on your phone. No symptom diary, no data trail.
We only ever ask for one date. No daily symptom logging — by design, not as a limitation.
Questions
Fair questions
The things we’d want to know before giving an app our cycle date.
Is Onda another cycle tracker?
No — and you don’t have to switch. Keep Flo or Clue for tracking; Onda is the layer on top that turns where you are in your cycle into a daily plan for training and food.
Do I have to log symptoms every day?
Never. Setup is one date — your last period start — plus your cycle length, once. No daily check-ins, no streaks to maintain. That’s by design, not a missing feature.
How does it know my phase without daily input?
Phase timing follows well-documented hormonal patterns — the luteal phase, for example, runs about 14 days for almost everyone. Onda does that math on your phone, fresh every day.
What if my cycle isn’t exactly 28 days — or I’m on hormonal birth control?
You set your own cycle length, and the plan scales to it. When a new period starts, updating the date is one tap from the main screen. If your cycle varies a lot month to month, predictions get less precise — each update brings Onda back in sync with your body.
And if you’re on hormonal birth control, Onda asks about it during setup: methods that suppress ovulation change the picture, and we adjust honestly — including telling you when phase-based planning doesn’t apply, instead of pretending it does.
What happens with my data?
The one date stays on your phone for the phase math. We never sell it or share it with ad or analytics companies. Your waitlist email is used for exactly one thing: the launch email.
Is this medical advice?
No — Onda is educational content based on published research on cycle physiology. It doesn’t diagnose or treat anything. For medical questions, talk to a clinician.
