For mental health professionals
Feellow is a B2B2C application founded on scientific psychology. Designed to integrate into the therapeutic relationship, never to replace it. Your sessions start from facts, not filtered memories. Opening to practitioners is planned for summer 2027: until then, we are looking for partner psychologists to co-design the tool.
The problem
What your patients bring to sessions isn't their week. It's a reconstruction filtered by memory, current mood, and recall biases. Feellow exploratory survey with 239 respondents, March 2026.
64%
don't remember clearly what they experienced between two sessions.
45%
have already forgotten to bring up an important topic during a session.
25%
stopped a mood journal because "nobody was reading their notes".
Our position
It helps you write, not think. It structures clinical material, it doesn't treat it. This position is written into our founding ethical charter, which is public and enforceable.
Scientific framework
EMA (Ecological Momentary Assessment) is a methodological paradigm that consists of measuring the person's experience at the moment they live it, in their natural environment. Not in session, not retrospectively. Shiffman, Stone & Hufford (2008), Annual Review of Clinical Psychology. Perski et al. (2022), Health Psychology Review. The Feellow check-in takes less than thirty seconds, several times a day, in line with validated protocols.
Three recall biases that EMA corrects at the source: negativity bias, mood-congruent memory, peak-end rule.
Therapeutic alliance
The therapeutic alliance is the primary predictor of outcomes in psychotherapy. Research shows that structured tracking between sessions strengthens it measurably.
r = 0.275
Correlation between alliance and therapeutic outcomes. Meta-analysis by Horvath et al. (2011), confirmed by Flückiger et al. (2018). Tripartite conceptualization of alliance (goals, tasks, bond): Bordin (1979).
+65%
of at-risk patients better detected with between-session monitoring. Lambert (2013). Structured monitoring allows anticipating clinical ruptures before they set in.
d = 0.51
Effect of between-session work on therapeutic outcomes. Meta-analysis by Kazantzis et al. (2016), Cognitive Therapy and Research. Medium to large effect size according to Cohen's standards.
A 45-minute session per week represents 0.4% of your patient's waking life. Feellow helps them put into words what they live the rest of the time.
"The therapeutic alliance is conceptualized as tripartite: agreement on goals, agreement on tasks, and an affective bond between patient and therapist."
Patient side
01
The app generates hypotheses about the patient from their data. The patient validates or rejects them with a swipe. Self-observation becomes an active cognitive act, not a passive journal.
Swann (1983, 2012) · Loewenstein (1994) · Roediger & Karpicke (2006)
02
Each past check-in gains value over time. In month 1, an isolated dot. In month 6, the anchor of a correlation. Perceived value increases without guilt, because it's real and tangible.
Kahneman, Knetsch & Thaler (1990)
03
Each month, the app generates a short narrative chapter recounting the patient's emotional month. Not a dashboard, a text. Storytelling, not clinical analysis.
McAdams (1985, 2001)
Your tool
Visualization inspired by psychopathological network models. You keep clinical control: raw data accessible, not just the synthetic summary. Borsboom & Cramer, 2013; Bringmann et al., 2013.
01
Each patient linked to your practice feeds their file. Pearson and Spearman coefficients between key dimensions (mood, sleep, exercise, anxiety, work) to explore clinical hypotheses.
02
A synthetic summary between each session, to read or listen to on the go. Raw data accessible in one click. Note format co-designed with partner practitioners.
03
Integrated scheduling on both practitioner and patient side. Messaging for short exchanges between sessions, within clinical boundaries. No urgency, no session substitute.
04
Automatic transcription, audio immediately deleted. Alert system calibrated on the SCS-C (Suicide Crisis Syndrome) in V2. The alert comes directly to you, never to the patient.
The patient chooses in the app what reaches you. They can change it at any time. On your side, your session notes remain in your private space. Confidentiality works both ways.
Ethical and technical safeguards
Voice is biometric data under GDPR art. 9. No audio file is ever kept.
The practitioner never sees engagement data (streaks, retention, usage behavior). Locked at the SQL architecture level.
No guilt-inducing streaks, no false urgency, one notification per day, never a follow-up.
Scientific research only, ethical university labs, granular opt-in. No pharma, no insurance, no marketing.
Data encrypted and hosted in France. Opening to practitioners, targeted for summer 2027, will only take place once HDS-certified hosting (French Health Data Hosting) is in place, as required by the French Public Health Code.
They choose in the app what they transmit to their practitioner and can change it at any time. Informed, granular, revocable consent, compliant with GDPR art. 7 and 9.
Compliance stack: external DPO appointed before opening to practitioners, DPIA v0.2 finalized, professional liability insurance (Hiscox), AES-256 encryption, PostgreSQL RLS. Read the full ethical charter.

Become a partner practitioner
Right now, we can show you the user application on a phone and discuss what would genuinely be useful in your practice. The idea isn't to sell you a dashboard, but to understand your needs before building it. In exchange for your time, practitioner access is free for one year for psychologists joining this co-design phase.
