What Daylio does

Daylio is a mobile-only consumer application that enables individuals to track mood and daily activities through a two-tap interface without writing. Developed and published by Habitics s.r.o., a private limited company headquartered in Bratislava, Slovakia, the app has operated since 2015 and reports more than 20 million cumulative users across iOS and Android. The product is positioned as a self-care bullet journal and happiness tracker, with features including customizable mood scales (5 to 10 points, with optional energy axes), activity tagging, photo and voice attachments, writing templates, goal and habit tracking, "Year in Pixels" visualization, advanced correlation statistics, PIN/biometric lock, and PDF/CSV export.

Technically, Daylio is built around an on-device-first architecture: all entries are stored locally, processed locally, and only optionally backed up to the user's private Google Drive (Android) or iCloud (iOS) storage. The company does not operate its own server-side data store and exposes no public API or web/desktop surface. Optional integrations include Apple Health (read/write of health metrics) and standard mobile analytics and crash-reporting SDKs (Firebase Analytics and Crashlytics) configured for anonymized, aggregated data collection only.

The business model is freemium with three monetization constructs on top of a free unlimited tier: monthly subscription, annual subscription, and a one-time perpetual purchase, each gated behind a 7-day free trial. Distribution is exclusively through the Apple App Store and Google Play Store, with acquisition driven by app store optimization, organic press coverage (Forbes, The Guardian, Mashable, Lifehacker), and word-of-mouth across Reddit mental-health communities rather than paid marketing. The organization is small (11-50 employees) and self-funded with no recorded external funding rounds. The addressable customer base is segmented across general mental-wellness users, individuals managing diagnosed mood disorders (e.g., bipolar disorder, anxiety, depression), and habit-tracking/self-improvement enthusiasts, with therapist recommendations emerging organically rather than via formal partnerships.
