A calm, private space to check in, track how you're really feeling, and never worry about your data. Mood diary, wellbeing score, medication log — designed for people living with depression or anxiety.
Chat with Lumi when you need to. Log your mood in four taps. Complete a two-minute wellbeing check-in once a week. Keep a private medication diary. Generate a clean PDF report to share with your GP. That's it.
Lumi isn't a therapy replacement and it isn't a clinical tool. It's a thoughtful companion that helps you notice patterns, prepare for appointments, and feel less alone with how you feel.
Vent, reflect, or just feel heard. Lumi listens without judging, notices patterns over time, and gently helps you make sense of how you're feeling.
Good, Low, Anxious, or Flat. Build a picture of your mood over weeks and months — without effort, and never a guilt-trip for skipping a day.
The S8 takes two minutes a week. See your score trend, your severity band, and your anxiety flag — in plain language, never clinical jargon.
Track doses, timings, and side-effect notes. Lumi never comments on your medication. This space is yours alone — useful when something shifts.
Generate a clear PDF of your S8 scores, mood summary, and medication log. Share it with your GP or therapist — make the most of fifteen minutes.
Everything is stored under an anonymous ID, encrypted, and held on servers inside the UK & EU. Export or delete all your data at any time.
The S8 is a short, 8-item wellbeing check-in. Each week you get a score, a severity band, and an anxiety flag — written in plain English. Watch the trend, not the number.
We never ask for your name or your email. Everything you record is stored anonymously, encrypted, and held on servers inside the UK and EU. Export or delete it any time.
The same gentle, evidence-rooted feed that appears inside the app — refreshed each week. Open a piece, take what's useful, leave the rest.

Quiet updates.
No shouting.
We post sparingly. When we do, it's a small new feature, a thoughtful piece of writing, or a heads-up that the app has landed on the App Store.
