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 โ that's the point of zero-knowledge architecture.
Metamorphic's answer
Metamorphic is a zero-knowledge, end-to-end encrypted habit tracker โ 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 โ not even your email address.
Metamorphic's answer
Most habit trackers store your data in plaintext on their servers. Metamorphic never sees your data โ 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 โ no trade-off required.
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 โ daily habits, long-term goals, journaling, scheduling โ 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.
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 โ built on an asymmetric, password-derived key architecture.
The idea for Metamorphic itself came from his partner, who is passionate about psychology and behavior โ 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.
Metamorphic's answer
React Engine might be a bit more popular than Metamorphic. We know about 1 link to it since March 2021 and only 1 link to Metamorphic. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
I'm the solo dev at Moss Piglet, a bootstrapped public benefit company. I've been building Metamorphic โ a habit and self-improvement tracker where all personal data is encrypted client-side before it ever reaches the server. The server only stores opaque cipher-text blobs. - Source: dev.to / 4 months ago
