Comparison
Day One lands on Depends, and Daylio lands on Worth it.
Buy if you journal daily across devices and want encrypted sync.
Buy it if you want a dead-simple personal mood and habit tracker . the free tier works, and a ~€40 one-time lifetime upgrade beats subscribing.
| Compare | Day One | Daylio |
|---|---|---|
| Verdict | Depends | Worth it |
| Best for | Daily personal journalers | Personal mood and habit tracking |
| Who it's not for | Businesses or teams . this is a personal diary, not collaboration software | Chronic illness symptom tracking . Bearable fits better |
| Privacy | End-to-end encryption for sync, dedicated security and privacy pages.⁴ | No known public vulnerabilities found in the sources reviewed; vendor claims local, locked data, but users flag unencrypted cloud backups. |
| Support quality | Only forum chatter found, no verdict | No evidence either way |
| Public sentiment | Longtime users love the app, but the $50/year price hike and lag complaints are pushing some toward alternatives.⁶ | Users love Daylio as a lightweight, two-tap mood and habit logger with genuinely useful long-term insights, though a minority report logging fatigue.11 |
| Biggest gotcha | Price jumped to $49.99/year; several public posts describe quitting over the hike.⁵ | Users report cloud backups are unencrypted; check backup settings before storing sensitive entries |
