Sarenica: Honest Self-Insight

Most wellness apps tell you what you want to hear. Sarenica tells you what your data actually says — including when it can't tell yet

Sarenica turns your everyday signals — screen time, app use, focus, sleep, steps, heart rate — into honest, personal insights about how your habits affect your sleep, focus, and energy. Every insight is computed from YOUR own data and shown with the real numbers behind it

WHAT MAKES IT DIFFERENT: HONESTY BY DESIGN
• It shows the actual result — the strength, the sample size, the uncertainty — never a vague "you should do X."
• When there isn't enough data yet, it says so plainly instead of guessing.
• Everything is association, not proof — we never dress up a correlation as a cause.
• No ads. No selling your data. No dark patterns.

RUN YOUR OWN EXPERIMENTS
Curious whether less screen time before bed actually improves YOUR sleep? Sarenica helps you run a simple, honest n-of-1 experiment: it sets a baseline, tracks the change, and tells you — truthfully — whether it made a real difference for you

PRIVATE BY DEFAULT
• Local-first: your raw data is designed to stay on your device.
• On-device intelligence: on supported phones, your insights are explained right on your device — your raw data doesn't leave.
• You control what's tracked, can disconnect any integration, and can delete your account and data at any time

WHAT IT CAN USE (all with your permission)
• Screen time and app usage patterns
• Focus and on-screen attention signals
• Optional camera-based fatigue signals — processed on your device, frames never stored or sent
• Wearable and health data you choose to connect (e.g. sleep, heart rate, steps)
• Weather context for a chosen home city

WHO IT'S FOR
Anyone who wants clear, trustworthy answers about their own habits — without the hype, guilt-trips, or false certainty of typical wellness apps.

Sarenica is a wellness and self-understanding tool. It is not a medical device and does not diagnose, treat, or provide medical advice
