Yellow connects your sleep, body signals and daily check-ins to show you what’s actually going on. So you can stop wondering and start understanding.
This is perimenopause. It’s physiological, not psychological. And when you can see it, you can stop being afraid of it.
Yellow reads your body, listens to your day, and translates what it finds into language. Not numbers.
No manual logging for the basics. Yellow listens, and translates.
The connection you couldn’t see, surfaced in plain language.
End-to-end encrypted. We never sell health data. Yellow only reads from Apple Health. It never writes back.
A daily moment. State, intensity, body, context. Yellow logs every part so you don't have to remember.
When something needs more than insight, Yellow offers two-minute practices for the right now.
Over days and weeks, you start to see what tends to come before the hard moments. And what helps.
Not everything can wait for insight. Sometimes you just need to get through the next ten minutes.
Guided somatic practices. Care scripts for partners, doctors, and yourself. Breathing tools. Short enough to use in the middle of a hard morning.
Your nervous system asking for help. Here's how to answer it.
Irritability in perimenopause is neurological, not temperamental.
For the 4am wake-ups that won't end.
For days when the weight is in your chest, not your calendar.
For the moments your body turns up the heat.
For when the word is right on the tip of your tongue.
HRV shifts before many women's most activated moments. Yellow reads yours and translates it from milliseconds into: Recovered, Steady, Low.
Disrupted sleep often precedes the harder days. Not as a cause. As a signal. Yellow helps you see the sequence.
Temperature shifts can appear days before symptoms surface. Yellow listens, in the background.
You weren’t imagining it.
Your body was telling you. You just didn’t have a translator.
No streaks. Your consistency is not a competition.
No “come back,” “you missed a day,” “don’t forget.”
No shame. No guilt. No failure language. Ever.
No scores. Quadrants are categories, not grades.
No raw numbers without translation. Data becomes language, not anxiety.
No diagnosis. Yellow names what's physiological. It doesn't prescribe.
No upsells. No locked features. No “upgrade now.”
No writing back to your health data. Yellow only reads.
These aren’t product choices. They’re what we believe health tracking should feel like.
“I showed my husband the pattern chart. He finally understood why Tuesdays are hard for me.”
“The first time Yellow said “Disrupted” instead of showing me sleep numbers, I actually exhaled.”
“I've been in perimenopause for two years. This is the first app that didn't make me feel like a wellness project.”
“The care script for talking to my doctor. I printed it out and brought it to my appointment.”
