# Sarenica: Honest Self-Insight > See what your habits actually do to your sleep, focus & energy — honestly Canonical page: [https://chrome-stats.com/d/com.sarenica.android](https://chrome-stats.com/d/com.sarenica.android) ## Overview - **ID:** `com.sarenica.android` - **Platform:** Android - **Type:** Android app - **Status:** Available - **Publisher:** Sarenica - **Category:** PRODUCTIVITY - **Downloads:** 2 - **Version:** 1.0.1 - **Last updated:** 2026-07-30 - **First published:** 2026-07-30 - **Publisher country:** IN - **Size:** 62 MB - **Data as of:** 2026-09-17 - **Store listing:** [Google Play Store](https://play.google.com/store/apps/details?id=com.sarenica.android) - **Website:** [https://sarenica.com](https://sarenica.com/) - **Privacy policy:** [https://sarenica.com/privacy](https://sarenica.com/privacy) ## Description 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 phone signals — screen time, app use, focus, steps — 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.

NO EXTRA HARDWARE NEEDED
Sarenica works on your phone alone. You do NOT need a smartwatch, wearable, chest strap, or any external device or accessory to use it. If you want to, you can optionally connect a wearable (for sleep or heart-rate data) — but this is an entirely optional add-on, and the app's core insights work fully without 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; everything beyond phone basics is optional)
• Screen time and app usage patterns
• Focus and attention patterns, inferred from how you use your apps (no camera or eye-tracking)
• Optional wearable and health data you choose to connect (e.g. sleep, heart rate, steps)
• Optional 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.
