Your period.
Your pill.
Your data.

Lumi is the calendar for your period and the reminder for your pill – and none of it ever leaves your iPhone.

I've got you. 🌸 Lumi, a little pink flower with a smiling face, waving from her garden

One question to start

Are you on the pill?

That decides what Lumi does for you. You can switch any time – your entries stay.

💊

Yes, I take the pill

  • Reminders only on pill days – during the break Lumi stays quiet
  • Follow-ups, mark as taken right from the notification, remind me later
  • Your supply at a glance, with a timely nudge about your prescription
  • Your withdrawal bleed is worked out from your schedule
🩸

No, just my cycle

  • Period calendar with a forecast based on your own cycles
  • A gentle reminder before your period is due
  • Bleeding, pain, symptoms and notes for each day
  • Optional: an estimated fertile window – an estimate, not suitable for contraception

What Lumi does

Not everything. Just what actually helps.

Today screen in cycle mode with the next period forecast

Knows when your period is due

From your own cycles or your pill schedule – as a date you can check yourself.

History with a day card and a list of cycles

Your history, honest

Tap a day and see everything: pill taken or missed, bleeding, pain, note – and your cycles as a list below.

Every cycle plants a flower

Lumi's garden grows with you – four styles, day and night, and a golden flower for every milestone.

🔔

Reminds you when it matters

Only on pill days. If you don't respond, Lumi follows up. Mark it as taken right from the notification.

Supply & prescription

Lumi knows which day you'll take the last pill you have at home – break days included – and reminds you about your prescription in time.

📝

How are you feeling today?

Bleeding, pain and how strong it is, symptoms, a note. Per day, all optional – for you and for your next appointment.

Light & dark

Follows your iPhone – in the evening Lumi turns cosy and dark on its own.

Stopped the pill?

Switch modes, done. Your entries stay.

🩺

Honest about what Lumi can't do

No medical advice, no statement about contraceptive protection. The estimated fertile window is only available in cycle mode, only if you turn it on – and always as an estimate.

New in 1.1 – and what else is inside

More Lumi, no clutter

Everything marked “New” arrived with version 1.1. And as always, it all stays on your iPhone.

A summary for your doctor

You choose the time range and sections, Lumi puts everything on one page as a PDF – with a sentence about you, if you like.

Backup as a file

One file with everything Lumi knows about you. Keep it in iCloud Drive, AirDrop it to yourself or store it in the Files app – on a new iPhone you restore it with two taps.

New

Switched pill?

A new schedule from a given day – say 21 + 7 instead of 24 + 4. Everything before stays in your history exactly as it was.
