Log ten seconds a day
Thirteen symptoms, graded none to a lot with one tap each. From the widget or the Lock Screen, without opening the app. Sleep, mood, and a note if you want one.
Perimenopause symptom tracker
Your cycle stopped keeping time. Your symptoms didn’t.
Solen never asks for your last period date. You log thirteen symptoms in about ten seconds a day, and it shows you what your own entries add up to: your patterns, your triggers, and how a fourteen-day change actually went.

How it works
Three steps. Your numbers.
See what your logs show
The trigger map compares your bad days with the rest: what your worst days have in common, on your own data. A first pattern shows up around day four, labeled provisional until it is real.
Change one thing for 14 days
Pick an experiment. Your baseline is already in your logs, so there is nothing to set up. Fourteen days later: the before, the during, and every single day in between.
4.2 a day before.
2.8 during.
That is how a Solen result reads. Not “it worked”, because fourteen days cannot prove that. The numbers, the raw daily chart, and a plain sentence about what they can and cannot show.

Measurement, not prediction
No forecasts.
No scores. We measure.
Period apps still ask for your last period date, because their predictions need a clock your body no longer keeps. Solen doesn’t predict anything. Forecasting hot flashes from self-reported logs would be guessing with a confident interface on top, and a wrong guess costs the one thing a health app runs on: your trust. So Solen records what actually happened, finds what your worst days have in common, and puts numbers behind any change you try.
The thirteen that matter, not a taxonomy of 84
- Hot flashes
- Night sweats
- Trouble sleeping
- Anxiety
- Low mood
- Brain fog
- Memory slips
- Fatigue
- Joint pain
- Headaches
- Low libido
- Irregular bleeding
- Weight change
Each one graded none, a little, fairly, a lot. Severity is the substrate: a pattern needs more than a checkbox.
The honesty rule
Solen never claims.
Solen shows.
You have heard confident claims for years, from apps and from waiting rooms. Solen holds itself to a stricter sentence.
A clueNot proof
“Lower during this period.” Never “this worked.”
A fourteen-day before and after is a clue, not proof. Symptoms fluctuate on their own, and expecting an improvement produces one. Solen reports what the numbers were and stops there.
13 of 14 days loggedstated on every card
The raw chart, every time.
Every summary ships with every single day, including the ones that don’t fit the story. Thin data is labeled provisional, next to the number of days it was computed from.
A skipped day is missing, never zero.
Every figure is computed only from the days you logged. Nothing is filled in on your behalf: no population averages, no model of what women your age usually report.
Your logs are yours.
Symptom logs are health data: readable only by you, never sold, never shared with advertisers, never used to train models. Delete your account from Settings and everything in it is erased immediately.
Solen is not a medical device and does not provide medical advice. The full method, in plain language: How Solen measures.
FAQ
Questions, answered.
When can I get Solen?
Solen is coming soon to the App Store, iPhone first. Email support@trysolen.com with the subject “Launch” and we will send exactly one email on launch day.
Is Solen a period tracker?
No. Solen never asks for your last period date and makes no cycle predictions. It is built for the years when cycles stop keeping time: you track symptoms, not dates. Irregular bleeding is on the symptom list like everything else, logged by severity rather than by calendar.
Where do the numbers come from?
From your own logs, and nowhere else. No population averages, no model of what women your age usually report, nothing filled in on your behalf. A day you did not log is treated as missing, never as zero, and every figure is shown next to the number of days it was computed from.
Can Solen predict my hot flashes?
No, and it does not try. Forecasting symptoms from self-reported logs would be guessing with a confident interface on top, and a wrong guess costs trust. Solen measures what actually happened: your patterns, your triggers, and how a fourteen-day change compared with the fortnight before it.
What does an experiment actually show?
Less than most apps imply, and Solen says so. A fourteen-day before and after is a clue, not proof: symptoms fluctuate on their own, and expecting an improvement produces one. So the result card reports the numbers, shows every single day including the ones that do not fit, and says "lower during this period" rather than "this worked".
Who can see my symptom logs?
Only you. Your logs are health data and we treat them as the most sensitive thing we hold: never sold, never shared with advertisers, never used to train models. Delete your account from Settings and everything in it is erased immediately.
Is this medical advice?
No. Solen is not a medical device and does not provide medical advice, diagnosis or treatment. It exists to put honest numbers behind what you are experiencing. The doctor-ready report is built so you can take those numbers to someone qualified.
How much will it cost?
Solen is a subscription: $39.99 a year with a seven-day free trial, or $9.99 a month. Final pricing appears on the App Store page.
What about Android?
iPhone first. Android is on the list, not yet on the calendar.
