The 6 Best Mood Trackers That Connect to HRV in 2026
Most mood trackers do not touch your wearable data. These six actually do. Ranked by how deeply they connect to HRV, sleep, and recovery from Oura, Whoop, Apple Watch, and Garmin.
By Omar Rantisi, Founder of Therma
How we ranked them
HRV is the single most useful biometric for understanding mood. But most mood-tracking apps ignore it. We ranked each app on four criteria: depth of HRV integration (native device support versus Apple Health bridge), interpretation (does the app explain what your HRV means for your mood or just show a chart?), daily friction (can you actually use it every day without burnout?), and privacy (who can see the combined mood and HRV data?). Tested over multiple weeks of real use. No paid placements.
The 6 picks
Best overallTherma
Free tier (waitlist), paid tier TBDBest forPeople who want AI interpretation of how their HRV, sleep, and mood move togetherTherma is the only app on this list built from the ground up to connect HRV to mood and interpret the pattern, not just show it as two separate charts. The 60-second daily mood check-in pulls HRV, sleep, and recovery data from Oura, Whoop, and Apple Watch natively (not via Apple Health) and feeds it into an AI that produces a weekly insight reveal. If the question you are asking is why your HRV is low on Tuesdays, Therma is the only app here that will actually try to answer it. Disclosure: our app.
Pros
- Native integration with Oura, Whoop, and Apple Watch (not via Apple Health bridge)
- AI weekly insight reveals that interpret HRV and mood patterns together
- One precise daily question that adapts to recent HRV and sleep data
- Calm, narrative tone instead of a raw dashboard
- End-to-end encrypted by default
Cons
- iOS only at launch (Q2 2026)
- Currently waitlist phase
#2Welltory
Free tier, premium around $49.99/yrBest forPeople who want HRV measurement and stress scoring as the primary featureWelltory is an HRV tracker with a mood layer, not a mood tracker with HRV. You can measure HRV from your phone camera or sync from Apple Watch, Garmin, and others. It gives you a daily stress and energy score and lets you log mood alongside it. The HRV depth is strong. The mood interpretation is basic by comparison.
Pros
- Strong HRV measurement (phone camera or wearable)
- Supports Apple Watch, Garmin, and several other devices
- Daily stress and energy scores based on HRV
- Mature product with active development
Cons
- Mood tracking is secondary to HRV measurement
- No AI interpretation of mood and HRV together
- Premium pricing is high for a single-purpose tool
#3HRV4Training
$9.99 one-time on iOSBest forAthletes who want evidence-based HRV analysis with mood and training load contextHRV4Training is the athlete-focused HRV app, built by a sports scientist. You log mood and subjective wellness alongside HRV (measured via phone camera or Apple Watch), and the app correlates HRV trends with training load. It is the most scientifically grounded option on this list for athletes, but it is dense and not aimed at general self-awareness.
Pros
- Strong scientific grounding (peer-reviewed methodology)
- Athlete-focused training load context
- One-time purchase, no subscription
- Mood logging is built into the daily flow
Cons
- Dense and technical, aimed at serious athletes
- No AI or narrative interpretation
- Mood is a single slider, not meaningful emotional tracking
#4Bearable
Free tier, premium $4.99/moBest forPeople with chronic conditions who want HRV context alongside symptoms and medicationsBearable can pull HRV data through Apple Health and correlate it with mood, symptoms, medications, and triggers. The correlation charts are useful if you have a chronic condition. The HRV integration is indirect (via Apple Health, not native) and there is no AI interpretation, just raw charts.
Pros
- HRV data flows in via Apple Health
- Excellent correlation with symptoms, medications, sleep, triggers
- Doctor-ready PDF reports at Premium tier
- Free tier is usable
Cons
- HRV integration is via Apple Health, not native
- No AI or narrative interpretation
- Dense, clinical UI built for illness management
#5CardioMood
Varies (B2B / professional pricing)Best forCoaches and clinicians who want HRV dashboards with mood and wellness logs for clientsCardioMood is a professional wellness platform that combines HRV, mood, and wellness logs into a dashboard. It is mainly aimed at coaches, clinicians, and health professionals who manage clients, not at individual users for daily self-awareness. If you work with clients and want a dashboard, this is a real option. If you are tracking your own mood, it is overkill.
Pros
- Professional-grade HRV dashboards
- Supports multiple wearables and clients
- Strong for coaching and clinical contexts
Cons
- Built for professionals, not individual users
- No consumer pricing
- Friction is high for daily individual use
#6Apple Health (as a mood tracker)
FreeBest forPeople who already have an Apple Watch and just want the basics in one placeApple Health added a mood logging feature in 2023 and it pulls HRV from Apple Watch automatically. You can see mood alongside HRV in the Health app. There is zero interpretation, the UI is not built for reflection, and Apple does not do the work of connecting the two. But it is already on your phone and it is free, which is worth something.
Pros
- Already installed on every iPhone
- Automatic HRV from Apple Watch
- Free
- Privacy is handled by Apple, not a third party
Cons
- Mood logging is basic (five options, no granularity)
- No interpretation or insights
- Not built for reflection or daily check-in
Methodology
Each app was tested over multiple weeks. HRV integration depth was measured by whether the app could pull HRV directly from a wearable (native), through Apple Health (bridged), or not at all. Interpretation was measured by whether the app explained what the HRV and mood data meant together, or just displayed both as separate charts. Pricing is current as of April 2026. Therma is disclosed as our own product.
Common questions
Why does HRV matter for mood tracking?
HRV (heart rate variability) is one of the strongest physiological signals of stress, recovery, and emotional state. Low HRV tends to correlate with stress, fatigue, and poor recovery. High HRV tends to correlate with calm, rest, and good recovery. A mood tracker that does not know your HRV is missing one of the most useful variables in the picture.
Which mood tracker has the best Oura integration?
Therma is being built with native Oura integration (direct API connection, not via Apple Health), so it can pull sleep stages, HRV, and recovery data at full fidelity. Most other mood trackers on this list rely on Apple Health as a bridge, which loses some data granularity.
Can I connect Whoop to a mood tracker?
Whoop does not push to Apple Health by default, so most mood trackers cannot access Whoop data. Therma is being built with direct Whoop integration. Welltory also supports Whoop directly. Bearable and others currently do not.
Is there a free mood tracker with HRV integration?
Apple Health is free and pulls HRV from Apple Watch, but it is not built for mood reflection. Bearable has a free tier that pulls HRV via Apple Health. Therma will have a free tier at launch for waitlist members. For true HRV depth, most paid options are more useful than the free ones.
Can I see how my caffeine or workouts affect HRV and mood together?
Most of the apps on this list show you both variables but leave the interpretation to you. Therma is specifically designed to answer this question with its weekly insight reveal, which connects mood to sleep, HRV, caffeine, workouts, and other tracked behaviors. If you want the interpretation done for you, that is the core value proposition.
