Weightalyze

Weightalyze – Understand your weight, not just track it

Weightalyze is a weight tracker for people who want to know what's
behind their data. All health data stays exclusively on your device.
No account required.

Weightalyze is a personal tracking app – not a medical device
and not a substitute for professional medical advice.

📊 WEIGHT HISTORY WITH TREND ANALYSIS
Weightalyze doesn't just show your current value – it calculates
trends over time: weekly averages, moving averages and deviations
from your target pace, so you can spot movements before they
become obvious.

🔒 YOUR DATA BELONGS TO YOU
All measurements, trends and analyses stay locally on your device.
No mandatory cloud, no account, no tracking. Optionally, the app
reads existing data from Google Health Connect:
- Body weight & BMI
- Heart rate & HRV
- Blood pressure
- Steps & activity
- Sleep quality & more

⚙️ OFFLINE ANALYSIS WITHOUT AI
Even without an internet connection, Weightalyze analyses your
entries using rule-based logic. A built-in knowledge base delivers
structured feedback on your values – fully offline, no external
services required.

🤖 AI ANALYSIS (OPTIONAL)
Weightalyze supports multiple AI providers:

PREMIUM: Get started instantly – no API key, no own server.
Cloud AI analyses directly from the app.

Self-configured: Connect your own provider –
Anthropic Claude, OpenAI-compatible APIs or Ollama locally.
Full control over provider, data and costs.

⚠️ NOTE ON AI ANALYSES
AI-generated evaluations are guidance only – not verified facts.
Always double-check relevant values yourself. For health concerns
or questions about diagnosis and treatment, please consult
a qualified medical professional.
