Hot flashes, disrupted sleep, mood swings, brain fog, irregular cycles, and unexplained weight gain — perimenopause affects up to 12 different body systems simultaneously. tr8ck tracks them all and uses AI to reveal which patterns are connected, which aren't, and what you can actually do about it.

Perimenopause is the 4–10 year hormonal transition leading to menopause. Average onset is around age 45, but it can begin as early as 38. It ends when you've had 12 consecutive months without a period.
During perimenopause, estrogen and progesterone production becomes erratic before declining. This isn't a steady downward line — it's a years-long fluctuation, which is exactly why symptoms seem unpredictable. A week of good sleep can be followed by two weeks of night sweats. A good mood month can be followed by unexplained anxiety.
The challenge is that without data, you can't distinguish hormonal patterns from other causes. Is your sleep bad because of a poor sleep habit, stress, or luteal-phase night sweats? Is your weight gain dietary, or is it the metabolic shift that accompanies declining estrogen? Data answers these questions.
The most commonly reported perimenopause symptoms tracked in tr8ck include: irregular cycle lengths, difficulty falling or staying asleep, hot flashes and night sweats, mood swings and anxiety, low energy and brain fog, joint discomfort, and gradual weight redistribution toward the abdomen.
Most health apps track one thing. Perimenopause affects everything at once. tr8ck is built to capture the full picture — and find the connections your brain can't hold simultaneously.
Are your worst sleep nights cycle-correlated — consistently occurring in the week before an expected period? Or are they random? tr8ck's AI answers this after two weeks of combined sleep and cycle data. Hormonal sleep disruption has a specific pattern; other causes don't.
Research shows exercise reduces hot flash frequency and improves mood during perimenopause. But does it work for you, and how much is enough? tr8ck correlates your exercise logs with your mood and sleep scores to show your personal exercise-symptom relationship.
Mood variability during perimenopause often follows a hormonal rhythm — but anxiety can also spike independently. Daily mood logs in tr8ck, overlaid on cycle data, reveal whether your mood dips are predictable and hormonal or more situational and addressable through other means.
Declining estrogen shifts fat storage toward visceral fat. But not all weight gain during perimenopause is hormonal — some is dietary. Tracking both weekly weight and nutrition together reveals whether your weight trend changes are correlated with intake or independent of it.
If you're using HRT, progesterone supplements, or other medications, tr8ck's medication module logs timing and dosage — and tr8ck can reveal whether symptom severity correlates with your medication adherence or timing patterns.
After 14 days of multi-module tracking, tr8ck's AI begins surfacing personal correlations in plain language: "Your sleep quality is 1.8 points lower in the 5 days before your period, consistently." This kind of specific, data-backed insight is what you can actually bring to your doctor.
"Your sleep score drops by an average of 2.1 points in days 22–28 of your cycle. This pattern appears in 5 of your last 6 tracked cycles. Your worst sleep nights (score below 4) occur 3× more frequently in this window than in days 8–14."
This kind of cycle-correlated sleep data is actionable — you can proactively manage sleep hygiene in that window, and share it with your GP or gynaecologist as evidence of a hormonal pattern rather than a vague complaint.
Perimenopause affects your whole health picture. tr8ck's 13 modules track every dimension — and AI finds the connections.
