Find what's actually flaring you up.
Renya quietly correlates your logs across food, stress, sleep, activity and cycle — then tells you, in plain English, which patterns matter for your heavy-leg days.
Patterns we’re seeing
Based on the last 28 days of your logs
Dairy → heavy legs within 24h
Food3× more likely on dairy days
High-stress days
Stress+28% symptom severity vs calm days
Luteal phase
Cycle+18% bloating vs follicular
Illustrative example — your insights are personal to you.
No food shaming. Just patterns you can act on.
Renya doesn’t put foods on a naughty list or grade your days. It looks at what your own body tends to do — and shows you the connections you’d never spot in a notebook.
Your logs, quietly
doing the math
1. Log what you can
Meals, symptoms, sleep, stress, cycle — whatever you have. Renya works with partial data, not just perfect journals.
2. Renya runs 5 lenses
In the background, the app correlates your symptoms against food, stress, sleep, activity and cycle phase.
3. Get plain-English insights
No p-values, no spreadsheets. Just short, honest sentences about what tends to come before a heavy-leg day.
Five lenses on
one body
Food ↔ Symptoms
Which foods show up before flares.
“Tomato-heavy meals are linked to more heavy legs within 24 hours.”
How it’s detected · Looks at how your symptoms move in the 0–48h after each logged meal.
Stress ↔ Symptoms
How your nervous system shapes the day.
“High-stress days run about 30% heavier than calm ones.”
How it’s detected · Compares average severity on high-stress vs low-stress days you logged.
Sleep ↔ Symptoms
What short nights actually cost you.
“After nights under 6h, your legs feel heavier the next morning.”
How it’s detected · Compares severity after short-sleep vs long-sleep nights.
Activity ↔ Symptoms
Movement vs sedentary days.
“Active days are linked to lighter legs and less bloating.”
How it’s detected · Sorts days into active and sedentary using your habits and Apple Health, then compares.
Cycle ↔ Symptoms
How each phase tends to feel.
“Your luteal phase trends ~18% heavier than your follicular phase.”
How it’s detected · Buckets symptoms into menstrual, follicular, ovulation and luteal — with 1W / 1M / 3M views.
Plus two patterns you didn’t ask for
Day-of-week peaks
Renya flags weekdays that consistently run heavier — Mondays after long weekends, restaurant Saturdays, your call.
Trends over time
Once you have ~2 weeks of logs, you’ll see whether things are quietly improving or drifting the wrong way.
Not a food diary.
A pattern engine.
Automatic
No manual journaling math. Once you log, the correlations run themselves in the background.
Multi-signal
Food alone is a half-answer. Renya looks across 5 lenses, because flares rarely have one cause.
Honest
No insight is shown until there’s enough data behind it. You won’t get a “trigger” after one bad lunch.
Personal Triggers, answered
Better logs, sharper insights
