Description
DuomiFlow – Offline Price & Data Logger
Stop guessing. Start tracking.
DuomiFlow is a lightweight, privacy-first tool for manually recording prices, monitoring trends, and making data-driven decisions. No cloud. No ads. Just your data, safely on your device.
Why DuomiFlow?
We interact with prices daily—groceries, subscriptions, procurement, or assets. But without historical records, we rely on memory. DuomiFlow turns isolated numbers into long-term insights.
Key Features:
• Manual Price Tracking: Log product prices, recurring expenses, and procurement costs with ease.
• Visual Trend Analysis: Instantly see historical highs/lows, trend directions (up/down/sideways), and abnormal movements.
• Beyond Prices: Record market indicators, behavioral metrics, or any custom data points.
• 100% Offline & Private: No mandatory registration. No ads. No personal data collection. Your records stay strictly on your device.
Set Realistic Expectations:
DuomiFlow is NOT an automated market data platform or a trading system. It is a dedicated, manual recording engine designed to help you build personal trend awareness and make rational decisions based on real, historical data.
Track prices. Understand change. Decide with clarity.

V2.2.0 Update: Batch Import Is Here—Say Goodbye to Manual Entry!
In this update, we’ve completely reimagined the data entry process. Our goal is to free you from tedious typing so you can focus on what really matters—visualizing price trends.
【Key Features】
Batch Import (Excel/CSV): Simply prepare a basic spreadsheet and import years of price history in seconds. What used to take days now takes moments.
Auto-Structure Creation: No need to pre-set categories or platforms. The system automatically creates and links products, categories, brands, and channels directly from your spreadsheet.
Multi-Tag Support: Use the # symbol to assign multiple categories (e.g., Fruit#Imported#Organic). The system will automatically split and link them for smarter organization.
Versatile Use Cases: Perfect for importing purchase history, tracking price fluctuations, or building your own personal product database.
【Privacy First】
DuoMi Price Tracker adheres to a "Local Only" policy. All your data stays on your device—no cloud uploads, no tracking, and no data collection. Your records belong to you alone.
Update now and turn your spreadsheets into insights!

Display Mapping (Multi-Series Comparison Enhancement)
When multiple datasets exist at different scales, direct comparison in a single chart becomes ineffective.
For example:
Limit-up count: 0–100
Limit-down count: 0–100
Index level: 4000+
Large value gaps can obscure meaningful trend relationships.
Duomi introduces:
Display Mapping
You can apply a transformation formula to any dataset:
Add (+)
Subtract (−)
Multiply (×)
Divide (÷)
The chart will visualize the transformed values while preserving all original data.
Use Cases
• Large-value offset (e.g., index minus baseline)
• Unit conversion
• Same-scale comparison
• Structural trend analysis
Important
Affects chart visualization only
Does not modify original records
Raw values remain fully accessible
With Display Mapping, you gain clearer structural insight
without compromising data integrity.

What’s New in Version 2.0
This update is not about adding more features.
It’s a shift in how recording is understood.
What’s changed?
1. From recording prices to recording states
Prices are outcomes.
What truly matters is the movement and condition behind them.
You can now record not only prices, but also data that reflects market state.
2. Enhanced trend and range analysis
Trends are clearer, and changes are easier to observe over time.
Not for prediction — but for understanding.
3. Unified system for price objects and data objects
Prices and statistics now follow the same recording and comparison logic.
More consistency. Less cognitive friction.
4. Stronger privacy and data ownership
All data is stored locally by default.
No cloud dependency. Your data belongs to you.
5. Rebuilt onboarding and product narrative
We restructured how the app introduces itself —
so from the start, it’s clear this is not a market-quoting app.
This is not a more complex app.
It’s a clearer one.
Duomi 2.0 — helping you stay calm and conscious when facing prices and data.
Build 881875243v1.1.22026-01-27 06:30:10
Fixed: Resolved an issue where price reminders would trigger in an infinite loop.
Improved: Enhanced overall system stability for a smoother experience.
