renpho-data-extractor

Get your body scale data out of the Renpho app and into Google Sheets where it belongs.

What is this?

The Renpho app locks your health data in a local SQLite database on your phone. This project uses Frida to extract that database so you can actually use your own data. Once extracted, it syncs everything to Google Sheets with proper analytics.

Important: You don't need a Renpho account. The app stores measurements locally even without cloud sync, so you can use the scale completely offline and still extract your data.

Quick Start

# Install deps
uv sync

# Patch the APK with Frida gadget
uv run objection patchapk -s apk_files/base.apk

# Install patched APK on your phone, open the app, then:
./get_renpho_db.sh

# Sync to Google Sheets
uv run python renpho_to_sheets.py

Setup Details

Get the APK

Download Renpho Health APK from your preferred source and save as apk_files/base.apk. The patching process will create base.objection.apk which you install on your device.

Google Sheets API

1. Hit up Google Cloud Console
2. Enable Sheets API
3. Create OAuth 2.0 credentials
4. Download as credentials.json

First run opens a browser for auth. Token gets saved locally.

What You Get

Raw SQLite database with everything:

• Weight, BMI, body fat %, muscle mass
• Water %, bone mass, BMR
• Visceral fat, protein levels
• Historical data with timestamps

Google Sheets with:

• All raw measurements
• 7-day and 30-day averages
• Trend analysis
• Auto-generated charts

How It Works

1. Objection patches the APK with Frida gadget
2. Frida script runs inside the app and copies the database
3. ADB pulls it to your machine
4. Python script reads SQLite and pushes to Sheets

The Frida script (download_health_db.js) is minimal - just copies the database file. There's also renpho_monitor.js if you want to see what the app is doing under the hood.

Files That Matter

• get_renpho_db.sh - Main extraction script
• renpho_to_sheets.py - Google Sheets sync
• download_health_db.js - Frida script that grabs the database
• frida-gadget.config - Gadget config (listens on port 27042)

Notes

• Only works on Android
• Tested with Renpho Health v3.x
• Database format might change in future versions
• Your data stays local (except what you explicitly sync to Sheets)

Problems?

Frida can't connect: Make sure the patched app is running and ADB works

No database found: Log into the app first, take a measurement

Sheets API errors: Check your credentials.json and quota limits

APK won't install: Uninstall the original app first
