iPhone
Baseline is a private, beautifully simple mood tracker for anyone who wants to see their patterns clearly. It's completely free: no subscription, no ads, no account — and nothing you record ever leaves your iPhone.
Each day, log your mood as a single point or a range from low to high. Add your hours of sleep, flag the symptoms that matter to you, and jot a short note. Baseline charts it all on a clean, uncluttered timeline, so the shape of your weeks and months becomes clear at a glance.
WHAT YOU CAN TRACK
• Mood as a single point or a low-to-high range, every day
• Hours of sleep
• Symptom flags and a short daily note
• Week view in portrait, month view in landscape — just rotate your phone
YOUR DATA, YOURS ALONE
• No servers, no accounts, no analytics — the app works entirely offline
• Nothing you enter is ever sent anywhere
• Backups and exports carry no name or identifying information — only the data you choose to record
• Export your history as CSV, JSON, or a shareable image, and back up to your own Files
DESIGNED FOR CLARITY
• A calm, Swiss-modern-inspired chart built to be read, not fiddled with
• Full light and dark mode
• Built for iPhone
Whether you're keeping a shared record with your clinician, watching how sleep shapes your days, or simply keeping an honest log for yourself, Baseline gives you a quiet, focused place to do it.
Baseline is a personal self-tracking tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment.
