Metamorphic's answer

Metamorphic is a new product and we don't disclose customer names. By design, we know as little about our users as possible — that's the point of zero-knowledge architecture.

Mind Diary's answer:

MindDiary does not currently publicly disclose individual customer or practice names.

Metamorphic's answer

Metamorphic is a zero-knowledge, end-to-end encrypted habit tracker — every piece of user data is encrypted client-side before it ever reaches the server. Unlike competitors that treat encryption as a premium add-on, Metamorphic includes it on every plan, including Free. It also uses hybrid post-quantum cryptography (ML-KEM-768 + X25519), the same approach adopted by Signal and Apple iMessage, making it one of the first habit trackers with quantum-resistant key distribution. The server never stores plaintext — not even your email address.

Mind Diary's answer:

MindDiary connects what happens before, during, and between therapy sessions in one workspace. Alongside practice management features such as digital intake, appointments, telehealth, invoicing, and therapist-reviewed AI notes, MindDiary helps therapists maintain continuity between sessions through client journaling, check-ins, homework, and session preparation. Instead of treating each appointment as an isolated event, MindDiary brings relevant client context together over time so therapists can prepare for sessions with a clearer picture of progress, concerns, and between-session activity. AI-assisted features support the therapist rather than replacing professional judgement.

Metamorphic's answer

Most habit trackers store your data in plaintext on their servers. Metamorphic never sees your data — all encryption and decryption happens in your browser. If the server were fully compromised, an attacker would get only opaque ciphertext. Beyond privacy, Metamorphic is a complete self-improvement platform: habit tracking with streaks and drag-and-drop reordering, goal setting with milestones and progress bars, daily self-reflections with mood tracking, a full schedule and calendar with recurring events and printable views, progress insights with activity heatmaps, and family/group accountability with shared habits and goals. You get the depth of a full-featured tracker with the privacy of an E2E encrypted system — no trade-off required.

Mind Diary's answer:

MindDiary is designed specifically around therapy workflows rather than being a generic scheduling or medical practice-management system. It combines digital intake, client management, session preparation, therapist-reviewed AI note drafting, telehealth, appointments, invoicing, revenue follow-up, journaling, homework, and between-session check-ins in one platform. A key difference is MindDiary's focus on between-session engagement and longitudinal client context. Therapists can use permissioned journal entries, check-ins, homework, recent sessions, and other relevant information to prepare for upcoming appointments instead of piecing context together across multiple disconnected tools.

Metamorphic's answer

Privacy-conscious individuals and families who want a serious habit and self-improvement tool without surrendering their personal data to a third party. People who care about building better routines — daily habits, long-term goals, journaling, scheduling — but also care about who can read their data. Particularly relevant for anyone who has thought twice about logging personal struggles, health habits, or family goals into an app that stores everything in plaintext.

Mind Diary's answer:

MindDiary is built for counsellors, psychotherapists, therapists, psychologists, group practices, and therapy clinics. It is particularly suited to practitioners who want to reduce administrative work while improving continuity of care through digital intake, session preparation, clinical documentation support, client journaling, homework, check-ins, appointments, telehealth, and practice-management tools. MindDiary currently has a particular focus on therapy practices in Ireland and the United Kingdom, while the platform is designed to support therapists internationally.

Metamorphic's answer

Metamorphic grew out of a personal conviction. Its creator, Mark Thayer, was building another app (Mosslet) around the time he was becoming a new dad. Reading Shoshana Zuboff's The Age of Surveillance Capitalism made him want a better digital world for his child. When Meta rolled back end-to-end encryption on its direct messaging, he was pushed to implement real E2EE in Mosslet — built on an asymmetric, password-derived key architecture.

The idea for Metamorphic itself came from his partner, who is passionate about psychology and behavior — always thinking about how to break old habits and form better ones. It clicked: something as personal as your habits, goals, and daily reflections should be private to only you, and you shouldn't have to worry about it being otherwise. So Metamorphic was built from day one around zero-knowledge architecture, where encryption is the foundation rather than an afterthought.

Mind Diary's answer:

MindDiary was created around a simple observation: therapy software typically concentrates on what happens inside the appointment, while much of the useful context develops between sessions. Therapists often have intake information, notes, journals, homework, appointments, invoices, and client communications spread across different systems. MindDiary was built to bring these workflows together and make relevant longitudinal client context easier to use when preparing for the next session. The goal is not to automate therapy or replace clinical judgement. It is to give therapists a better workspace for understanding context, reducing administration, maintaining continuity between sessions, and running their practice.

Mind Diary's answer:

MindDiary is a modern cloud-based web application built primarily with React and TypeScript on the frontend and .NET/C# services on the backend. Its infrastructure uses technologies including AWS, Cloudflare, PostgreSQL, Stripe, and modern AI/LLM services. The platform is designed with security, privacy, scalability, and therapist control over AI-assisted workflows in mind.
