Somnologs: Sleep Diary

Somnologs is your sleep diary. In the evening you note your night in a few seconds, and day after day your habits take shape on their own. On the day of your appointment, you arrive with concrete reference points, your own, ready to share with your doctor.

No sensor to wear, no account to create. Just you, your nights, and a clear record of what happens once the lights go out.

What you can do
• Log your nights and naps: bedtime and wake time, how long to fall asleep, awakenings, how rested you felt, your morning shape. Thirty seconds, even on tired evenings.
• See your trends: efficiency, sleep time, how steady your schedule is, week after week.
• Set a sleep objective (bedtime and wake time) and track, night after night, whether you keep it.
• Turn on the reminders you want: log your night so you don't forget like on paper, your bedtime to keep your objective, your medication and your appointments.
• Add your own labels (sport, coffee, travel...) and watch what changes in your nights.
• Get ready for the appointment: a clean PDF diary, night by night, to print or send to your healthcare professional.
• Wind down before bed with a guided, full-screen coherent breathing exercise.
• Find a sleep center near you, among more than 500 listed in France.
• Read a few clear, sourced sleep-hygiene articles.

Your data stays with you
Everything is stored on your phone, nothing goes to our servers. You export, share or erase your nights whenever you decide. Face ID lock if you want it.

Somnologs is a wellness app, not a medical device: it makes no diagnosis. If your sleep difficulties last, talk to a healthcare professional.
