Your feelings are your business. Period.

We engineered Feel so that only your eyes can decrypt your soul. Entries are encrypted on your device before they ever touch our servers β€” and decrypted only when you unlock the app. No backdoors. No data mining. Not even our developers can read what you write.

Client-side encryption

Your data is sealed on your device with a key only you hold. We see ciphertext, never content.

Server Encryption

On the server, recordings are automatically encrypted with an additional server key. Developers cannot read your recordings even without a password.

Zero-knowledge servers

Even with full server access, an attacker would find a vault of meaningless cipher blocks.

No third parties

No ads. No analytics on your entries. No shipped data to anyone, ever.

ENCRYPTED

One toolkit.
Three lenses on the inner world.

Each tool is purpose-built for a specific job β€” daily measurement, session preparation, life-wide assessment. Use one. Use all three. They share a single encrypted vault.

The Intensity Tracker

Log a feeling in 7 seconds. Watch a week of emotional weather render itself into something you can actually read β€” stacked bars, dominant categories, intensity averages.

  • 5 categories: Love, Joy, Sadness, Fear, Anger
  • Granular intensity scale 1–10
  • 7-day, 30-day, and yearly trends
  • Pattern detection across triggers

Track. Analyze.
Discuss.

Feel sits between your day-to-day and your next session. The loop closes itself β€” you bring data, your therapist brings insight, and progress becomes legible.

01

Track daily

Twenty seconds, twice a day. Tag the feeling, set intensity, optionally write a sentence.

02

Analyze trends

Patterns surface in week and month views. Triggers, peaks, recoveries β€” visible at a glance.

03

Discuss in therapy

Walk in with a brief, not a blank slate. Sessions move from catch-up to actual work.

β€œ
Mental health isn't a bug to be patched. It's a system to be navigated β€” with the right instruments.
