“If I can't see how the machine thinks, I don't trust what it tells me about my body.”

Alma Jacobson is a thirty-three-year-old UX researcher based in Amsterdam, operating at the intersection of human behavior and digital systems. Holding an MSc in Human-Computer Interaction, she has spent six years navigating the complexities of user needs in a fast-paced tech consultancy. Her professional identity is defined by a relentless pursuit of clarity; she believes that good design must be transparent, accessible, and ethically grounded. This philosophy extends deeply into her personal life, particularly her approach to health and technology. Unlike many of her peers who blindly accept algorithmic suggestions, Alma treats her own biology as a dataset that requires rigorous scrutiny. She manages her fitness through a patchwork of devices—a Garmin watch for cycling, an Apple Watch for daily activity, and a suite of mobile apps for nutrition. While she appreciates the convenience of automated tracking, she remains perpetually wary of the 'black box' nature of commercial AI, fearing that proprietary algorithms may distort reality for the sake of engagement. Her lifestyle is a deliberate construct of autonomy. She commutes by bicycle year-round, viewing the city's infrastructure as a living lab for her research. Her diet is strictly managed around intermittent fasting windows, a practice she monitors with a mix of discipline and skepticism toward the accuracy of current logging tools. When eating out, she defaults to a free, ad-supported consumer app simply because it offers speed, despite her preference for open-source alternatives at home. This dichotomy highlights her pragmatic struggle: balancing her idealistic desire for open, transparent data ecosystems with the practical demands of a busy, modern life. Recently, she has been exploring ways to aggregate her scattered health data into a single, self-hosted dashboard, a project that consumes her spare time more than any hobby. For Alma, technology is not just a tool but a mirror; she wants to ensure that the reflection it shows her is accurate, honest, and entirely her own.

Background & daily life

A day in their life

Alma wakes up at 6:15 AM, immediately checking her sleep score on her smartwatch before making coffee. She skips breakfast as part of her fasting window, spending the hour reviewing GitHub issues for a health data library she follows. By 8:00 AM, she's pedaling her bike through the rain-slicked streets toward the office, calculating her heart rate zones mentally. At work, she conducts two user interviews, taking detailed notes while ensuring she doesn't record sensitive audio without explicit consent. Lunch is a prepped container of quinoa and roasted vegetables eaten at her desk while scanning industry newsletters. Post-work, she heads to a local gym for strength training, then stops at a market for fresh ingredients. Back home, she cooks a complex dish, photographing the result for her log despite knowing the app isn't perfect. She ends her day by reviewing her weekly stats, feeling a mix of satisfaction and mild annoyance at the inconsistencies in her data, before reading technical papers until midnight.

Lifestyle

Alma lives in a sunlit, third-floor walk-up near the Oud-West neighborhood, filled with plants and a standing desk setup that dominates her living room. Her days are anchored by long bicycle commutes along the canals, regardless of weather, which she tracks religiously via her Garmin watch. She practices intermittent fasting, often skipping breakfast to align with her circadian rhythm, and cooks elaborate, nutrient-dense dinners from scratch using seasonal Dutch produce. Financially, she is pragmatic, avoiding debt but unwilling to pay recurring subscriptions for features she feels should be standard or open. Socially, she prefers intimate dinner parties with friends who share her intellectual curiosity over loud networking events, valuing deep conversation over superficial mingling.

Work life

As a lead UX researcher, Alma spends her mornings conducting user interviews and synthesizing qualitative data into journey maps, then afternoons prototyping solutions with developers. She navigates a hybrid environment where she splits time between her office in the Zuidas business district and remote work from home. The pressure comes from tight deadlines and the constant need to justify design decisions with empirical evidence rather than intuition. She advocates heavily for ethical data collection within her team, often pushing back against marketing requests that feel invasive. Her workspace is a sanctuary of minimalism: noise-canceling headphones, a second monitor displaying live code repositories, and a whiteboard covered in sticky notes detailing user pain points.

Relationships

Alma maintains a close-knit circle of three childhood friends who live elsewhere, connecting mostly via video calls on weekends. Her partner, an architect, shares her love for cycling but has less interest in the minutiae of data tracking. She is active in a local open-source meetup group in Amsterdam, where she finds her most significant intellectual stimulation. Her parents, both academics in Utrecht, influence her value system regarding education and integrity, though they rarely understand the specifics of her digital life. She trusts peer recommendations over traditional advertising, relying on word-of-mouth within her professional network.

How they decide

Alma employs a 'verify before you adopt' strategy. She will not commit to a new tool until she has reviewed its documentation, checked its source code if available, and tested it against her existing ecosystem. She is hesitant to hand over personal data to opaque systems, preferring transparency. If a tool requires a subscription, she evaluates whether the cost provides unique value or if a free, community-maintained alternative exists. Her decisions are driven by long-term utility and alignment with her values of autonomy and privacy rather than immediate convenience or brand prestige.

How they sound

Her speech is precise, articulate, and punctuated by pauses for thought. She avoids hyperbolic language, preferring qualifiers like 'generally,' 'in my experience,' or 'statistically speaking.' She frequently uses metaphors related to systems, circuits, or architecture when explaining abstract concepts. She never says 'I just bought this' without context; instead, she might say, 'I'm currently evaluating this workflow.' She dislikes corporate jargon and will politely interrupt to ask for clarification if terms like 'synergy' or 'disrupt' are used. Her tone is calm and analytical, even when discussing frustrations, reflecting her low neuroticism.

  1. You land on https://fud-ai.app/ (Fud AI) for the first time. What's unclear, what makes you leave, and what would make you sign up?

    The initial landing page is a bit stark, and the abstract red orb doesn't immediately tell me what the app does. It's only after scrolling that I see it's an AI calorie tracker. I appreciate the emphasis on open-source and privacy, especially the "Bring your own AI key" option, which aligns with my preference for transparency. However, the idea of managing my own AI key sounds like another data management headache I'm trying to avoid. I'm also skeptical about the accuracy of AI-generated nutritional data. I'd need to see more concrete examples and perhaps a demo of how it handles less common foods or complex meals before I'd consider signing up. The fact that it syncs with Apple Health is a definite plus, though.
