FAQ

Got questions? We’ve got answers.

From clots to app stuff, if it’s about your flow, we’ve probably covered it.

Still curious? Got thoughts? Just wanna chat cycle?
Hit us up at [email protected] – we’re all ears (and uteruses).

Because counting pads isn’t science – but this is.
Tracking your actual period volume isn’t just a vibe, it’s a power move.💡

A “typical” period is around 40-50mL per cycle, while anything over 80mL is considered heavy. Heavy periods could be linked to conditions like fibroids, PCOS, or endometriosis. Your flow changes over time.

Here’s why it matters:

  • 📊Know what’s normal (For You)
    Your flow, your rules — but data helps. Spot changes, weird patterns, or anything that’s off.
  • 🚨 Catch issues early
    Heavy flow? Giant clots? It could be more than “just a bad period.” Think: endo, PCOS, anaemia, fibroids. Get ahead of it.
  • 🩺 Slay your doctor visit
    Sick of being told “it’s probably fine”? Bring receipts. Real numbers = real conversations.
  • 💡 Body literacy > Guesswork
    We track steps, sleep, calories – why not blood loss?
    Knowing your flow is knowing yourself.
  • 📱 Science in your pocket
    Scan, track, compare. Period care has finally entered its data era.

Blood clots bigger than 2.5cm² (think a 5p coin or a dime) might be a red flag for things like fibroids. With Joii, you can track them over time and see if anything changes. Because knowing is always better than worrying. 😌

Joii isn’t just about flow tracking. It’s your period’s new BFF. 💕

✨ Pro tips for a perfect scan: 📸 Lay it flat – On your lap, countertop, or even in your underwear (as long as it’s flat). 📱 Match the outline – Hold your phone at a good distance. 💡 Good lighting helps – The app auto-uses flash for clarity.
