Most health apps were designed on male biology. They track metrics in isolation, ignore your cycle, and miss the connections that actually explain your health. tr8ck connects your cycle, mood, sleep, nutrition, exercise, and medications — and shows you the patterns no other app reveals.

Your estrogen, progesterone, testosterone, and LH levels shift dramatically across your 28-day cycle — affecting your sleep quality, strength, appetite, mood, and recovery. An app that doesn't account for this is giving you noise instead of insight.
Clue and Flo are excellent at predicting your period. But they don't connect cycle phase to your sleep quality, how hard your workouts feel, why you're craving carbs in the luteal phase, or why your mood dips predictably before your period.
Strava, Apple Fitness, and MyFitnessPal have no awareness of your cycle phase. Your strength peaks in the follicular phase, not the luteal phase — but these apps treat every workout the same, making inconsistent performance confusing instead of expected.
Progesterone and estrogen directly affect sleep architecture. Luteal phase progesterone spikes can disrupt REM sleep. Oura Ring tracks your sleep but doesn't connect it to your cycle phase — so you never know why your sleep deteriorates in the week before your period.
You'd need 5+ apps and a spreadsheet to see how your cycle phase affects everything else. tr8ck does it all in one place — with AI that finds the connections automatically.
tr8ck's modules aren't siloed features — they're an integrated health system designed around the complexity of women's physiology.
Log your period start/end and cycle length. tr8ck calculates your current phase and overlays it onto every other metric automatically. The cycle is the lens through which all other data is interpreted.
Your 1–10 daily mood score is displayed against your cycle phase timeline. When your mood consistently drops in the luteal phase, tr8ck surfaces it — distinguishing PMDD-like patterns from situational stress.
Log sleep quality and duration nightly. tr8ck identifies whether your worst sleep weeks systematically align with your luteal phase — the most common pattern for hormonal sleep disruption in women.
For women on Ozempic, Wegovy, or Mounjaro, tr8ck separates hormonal patterns from medication effects — showing whether weight changes, mood shifts, and appetite variation are driven by your cycle or your GLP-1.
