Journaling for mental health is not the same as journaling for creativity or productivity. When the goal is processing emotions, understanding patterns, and supporting your therapy, the app you use needs to do a few specific things well: low-friction entry, mood context, and a way to use what you write rather than just storing it.
Most journaling apps are built for general use. A few are built specifically for mental health. This list covers the best of both.
Symplia
symplia.app
The most therapy-specific option on this list. Symplia combines journaling with mood tracking, sleep and medication logging, and a session prep system that helps you build a clear note before each therapy appointment.
What makes it different from other journaling apps is that the journal is not an endpoint. The things you write throughout the week become material for your session prep. Your mood patterns become data your therapist can actually use. The journaling has a destination.
Voice-to-text journaling is available on the free trial and paid plans. The journal categories (therapy prep, reflection, growth, gratitude, processing, emotions, somatic) help organize entries in a way that is meaningful for therapy rather than just chronological.
Free 7-day trial. Paid plans from $12.99 per month.
Best for: people in therapy who want their journaling to connect directly to their sessions.
Day One
dayoneapp.com
Day One is the most polished general journaling app available. The design is excellent, the writing experience is genuinely pleasant, and it has features like multiple journals, location tagging, weather, and end-to-end encryption that most apps do not offer.
For mental health specifically, the free writing space is its strength. If you want a private, beautiful place to write without structure or prompts, Day One is the best option available.
The weakness for mental health specifically is that Day One does not analyze or do anything with what you write. It is a container, not a system.
Best for: people who want a private, high-quality writing space without structure.
Reflectly
reflectly.app
Reflectly is a guided journaling app that uses prompts to help you work through emotions. Each entry starts with a mood check-in and then asks questions to help you understand what is going on beneath the surface.
For people who find blank-page journaling difficult, the guided format is a genuine help. The prompts are thoughtful and the app does a reasonable job of making the process feel structured without being clinical.
Best for: people who need prompts to get started and want a more guided experience.
Bearable
bearable.app
Bearable leans more toward health tracking than journaling, but its note-taking and symptom-logging features make it a hybrid worth including. The correlation reports showing which factors affect your mood are something most journaling apps cannot produce.
Best for: people who want to track multiple health factors and see correlations over time.
Penzu
penzu.com
Penzu is a private online journal with strong security features including two-factor authentication and optional passcode protection. For people who are concerned about journal privacy, Penzu takes it more seriously than most apps.
Best for: people who prioritize privacy and want straightforward encrypted journaling.
Stoic
getstoic.com
Stoic is built around stoic philosophy, with morning and evening reflection routines, emotional check-ins, and exercises from the stoic tradition. The structured routines create a rhythm that many people find grounding.
Best for: people interested in stoic philosophy as a framework for managing emotions.
How to choose
If you are in therapy: Symplia, because the journaling connects directly to your sessions. If you want the best pure writing experience: Day One. If you need prompts to get started: Reflectly. If you want health factor correlations: Bearable. If privacy is the priority: Penzu. If you want a philosophical framework: Stoic.
