therma is the emotional layer for health tracking. wearables and health apps tell you what your body did. therma tells you how you felt while it was happening, and shows you where the two stories meet.

how it works - one check-in a day. a single question about how you actually feel. 30 seconds. - a companion that listens. chat through what's coming up in a voice that doesn't sound like a therapist or a chatbot. - synced with apple health. mood, sleep, activity, and heart data sit in one place.

feature update coming up in May for Mental Health Awareness month: - a sunday card. every week, one card showing what shifted: energy, sleep, what you wrote about, what you were doing.

built for people who suppress to perform.

founders, operators, parents, anyone who's good at functioning through their feelings. therma is for the moment that stops working. no streaks. no clinical register. just a private space to feel what you're actually feeling.

pricing - free forever - $9.99/mo or $59.99/yr (50% off annual) - founding member: $39.99/yr, locked for life. first 10,000 only.

Nullstack features and specs

  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages of Nullstack

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing Therma.one and Nullstack.

What makes your product unique?

Therma.one's answer

Most wellness apps live in their own bubble: mood tracking here, sleep tracking there, journaling somewhere else. Therma sits next to Apple Health and adds the one thing health data can't capture on its own: how you actually felt while it was happening.

One check-in a day. A companion that listens. A Sunday card showing what shifted. That's the whole product. Not a 50-feature wellness platform, not a meditation library, not a therapy replacement. Just the emotional layer your health stack is missing.

Why should a person choose your product over its competitors?

Therma.one's answer

Daylio gives you mood charts. Reflectly gives you AI journaling. Youper gives you CBT exercises. None of them connect to the rest of your health data, and most ask for more than 30 seconds a day.

Therma works the other way around. One question a day, low pressure, no streaks shaming you. Mood lives next to sleep, activity, and heart data inside Apple Health, so patterns surface without you hunting for them. And the weekly card does what most apps make you do yourself: tell you what's actually changing.

It's also priced for the long haul. Founding member pricing locks in $39.99/year for life for the first 10,000 subscribers.

How would you describe the primary audience of your product?

Therma.one's answer

People who suppress to perform.

Founders, operators, parents, athletes: anyone whose job depends on functioning through their feelings. They're already tracking their sleep, their workouts, their resting heart rate. They've got the body data covered. What they don't have is a way to see how the inside lines up with the outside, and a quiet space to feel what they're actually feeling without it becoming another performance metric.

Therma is for the moment when suppression stops working. Before burnout, before the relationship cracks, before the body forces the issue.

What's the story behind your product?

Therma.one's answer

Therma started from a personal pattern. I'd built businesses, performed on stages, hit physical goals, and the one thing I was worst at was knowing how I actually felt in real time. By the time something registered, I was usually three weeks past the moment that mattered.

Most wellness apps I tried felt clinical, gamified, or built for someone with more time and less ambivalence than I had. The founders, operators, and high-performers around me were running into the same wall.

Therma is the app I wanted: 30 seconds a day, no clinical register, synced with the health data I was already tracking, with a Sunday card that tells me what I missed. Tagline is "feel it to free it." That's the whole philosophy.

Which are the primary technologies used for building your product?

Therma.one's answer

  • iOS native (Swift, SwiftUI)
  • Google Vertex AI for the companion, built on a research library developed by humans
  • Apple HealthKit integration for mood, sleep, activity, and heart data
  • Metabase for product and cost analytics
  • Standard backend stack on Google Cloud
