Lumen
Private perimenopause companion
A warm, on-device companion for perimenopause — symptoms, cycle, and an AI coach, all private.
The Problem
Perimenopause brings confusing, shifting symptoms, but the apps that promise help often demand an account and quietly send your most intimate health data to their servers for analytics or ads.
The Solution
Lumen keeps everything on your device. Track symptoms and your cycle in a few taps, chat with a supportive AI coach, and get a short daily insight that reflects on your recent check-ins — with no account, no servers, and no data ever leaving your phone.
What you get
On-device AI coach
Chat with a supportive, knowledgeable coach about what you’re going through — your conversations stay on your phone.
Quick symptom & cycle tracking
Log hot flashes, sleep, mood, energy, anxiety, and your cycle in a few taps, and see gentle trends over the past week.
A daily insight
Once a day Lumen reads your recent logs and shares a short, encouraging insight with one gentle tip on the Today screen or Home Screen widget.
Apple Health sync
Optionally sync hot flashes, cycle, mood, and energy to Apple Health, and let Lumen read last night’s sleep to personalise your insight.
Gentle reminders
Opt in to a daily check-in reminder at a time that suits you.
Private by design
100% on-device with no network requests of any kind, no account, no tracking, and a “No Data Collected” privacy label.
Questions
- Does my health data leave my phone?
- No. Every bit of AI runs locally with Apple Intelligence, and there are no network requests of any kind — no account, no servers, and no analytics.
- What do I need to run it?
- A device that supports Apple Intelligence with it turned on. Lumen requires iOS 26 or later, and is a one-time purchase with no subscription.
- Can Lumen give medical advice?
- No. Lumen offers supportive information, not medical advice — it can’t diagnose conditions or prescribe treatment. For severe or sudden symptoms, contact a clinician or emergency services.
