InnerOS vs Harmony
Harmony is voice-first IFS, with a CBT mode and a relationship mode two people join together. InnerOS is text, for one person, on iOS and Android: ten parts of you answer in their own voices and the session ends in a next step.
Feature-by-Feature Comparison
| Feature | Harmony | InnerOS |
|---|---|---|
| Input | Voice-first, switchable to text | Text |
| Two people | Relationship mode for couples | Single-person only |
| Voices | One guide across modes | Ten archetypal voices in dialogue |
| After a session | Post-session analysis and parts maps | A concrete next step |
| Platforms | Web | iOS, Android |
Harmony Strengths
- Move between voice and text inside a single session
- A CBT mode for when parts work is not what the moment needs
- A relationship mode two people join together — nothing else in this category does that
- Post-session analysis with parts maps and other visualisations
- Carries memory across sessions
Harmony Limitations
- Web only
- Built around a guided session rather than parts arguing with each other
The Verdict
Harmony is the most session-shaped tool here and the only one built for two people at once. InnerOS is single-person, text, and pointed at ending a specific internal argument.
When to Choose InnerOS
If you want to talk out loud, or you want to do this with a partner in the room, Harmony does something we do not do at all. InnerOS is the better fit when the conflict is inside one person and the goal is a decision rather than a session.
Common Questions
What is Harmony, the IFS app?
Harmony is a voice-first IFS app. By its own site, you can switch between speaking and typing in one session, it has a CBT mode, and it has a relationship mode two people join together. It gives a post-session analysis with parts maps and carries memory across sessions. It runs on the web.
What is a good Harmony alternative?
InnerOS, if the conflict is inside one person and you want a decision. InnerOS is text, on iOS and Android, and gives ten parts of you their own voices, ending in a next step. If you want to speak out loud or do this with a partner, Harmony does that and InnerOS does not.
Does InnerOS support voice like Harmony?
No. InnerOS is text. If speaking rather than typing matters to you, Harmony is built voice-first and is the better choice. InnerOS is built for the moment two parts of you want opposite things, worked in writing to a concrete next step in about ten minutes.
Can two people use InnerOS together?
No. Harmony has a relationship mode where two people join one session and are guided through understanding each other. InnerOS works with the parts inside one person. For a conflict between two people rather than inside one, Harmony is aimed at that and we are not.
