Privacy-first wellness journal · iOS
Sentimo is an emotionally adaptive wellness journal. Track your mental landscape, capture private voice reflections locally, and detect background stress levels — privately, on-device.
On-device speech
Record voice check-ins to capture your raw feelings. Sentimo transcribes and analyzes your words directly on your Apple device to extract key themes — and the audio and transcript are erased immediately after. Zero cloud. Zero tracking.
Reflection captured. No audio or transcript is saved.
HealthKit + CoreML
Through secure HealthKit integration, Sentimo reads your heart rate and Heart Rate Variability (HRV). A custom on-device CoreML model quietly assesses whether you're in your Baseline zone, Agitated, or Stressed — prompting a calming check-in whenever your nervous system needs a breather.

Your privacy is the whole point.
Sentimo is designed with privacy as a core principle. All your mood data and personal information are stored locally on your device only. We do not collect, transmit, or store any personal data on external servers.
Voice reflections are transcribed and analyzed entirely on your device using Apple's on-device Speech Recognition. The audio recording and transcript are deleted immediately after a few private theme keywords are extracted. No audio or transcript is ever saved or uploaded.
If you enable stress detection, Sentimo reads heart rate and Heart Rate Variability from Apple Health to run an on-device model. This health data is processed locally and is never transmitted off your device.
Your data is protected by your device's built-in security features, including device encryption and passcode protection. We recommend keeping your device secure and updated.
We never share, sell, or transmit your personal data to third parties. Your information remains completely private to you.
You can delete all your data at any time using the "Reset All Data" option in Settings. You can also delete the app to remove all associated data from your device.

Get in touch with the Sentimo team.
Hi! I'm Emily Wallace, the creator of Sentimo. I'm passionate about building tools that help people understand and improve their emotional well-being. Sentimo was born from a desire to create a simple, private, and beautiful way to track mood patterns over time.
I believe mental health tools should be accessible, private, and empowering. That's why Sentimo keeps all your data on your device and focuses on helping you discover your own patterns rather than telling you what to feel.
I'd love to hear from you! Whether you have feedback, questions, or just want to share your experience with Sentimo, please don't hesitate to reach out.
