App Features

Accurate Dual Product Unit Price Comparison

Input the price, quantity, and unit of two different products for instant standardized calculation. The app supports all mainstream daily measurement units including gram, kilogram, milliliter, and liter. It automatically unifies measurement standards, calculates precise unit prices per gram or per milliliter, and visually marks the more cost-effective product to avoid premium shopping.

Complete Local History Record Management

All price comparison records are automatically saved locally and sorted in chronological order. Users can view past shopping comparison data at any time, search records by product name, and edit existing commodity parameters. Modify prices, specifications, or units to recalculate comparison results with one click for flexible data verification.

Professional Local Data Security Control

UnitCompare is a fully offline application with no network access, no data upload, and no private information collection. Users can delete single comparison records or clear all local data with one click, fully controlling personal shopping data and ensuring absolute privacy and data security.

Frequently Asked Questions

The app crashes or freezes when opening or calculating

Close redundant background applications to free up device memory and running resources. Ensure your device has sufficient available storage space for local data caching. Restart your device to clear temporary system cache files. If the problem still exists, uninstall and reinstall the app, local data will be retained normally.

Calculation results are abnormal or data deviation occurs

Check whether the input commodity price and specification values are valid, avoid inputting zero, negative numbers or empty values. Confirm that the selected weight or volume unit matches the actual commodity specification. Re-enter the correct parameters and click the calculate button again to get accurate unit price data.

Historical records cannot be viewed or edited

Do not use third-party cleaning tools to clear app local data casually. Ensure that the app has local storage access permission in device settings. If the record display is abnormal, restart the app to refresh the local data list.

Bilingual switching fails or interface text is displayed abnormally

Exit and re-enter the app after switching the language mode to ensure the setting takes effect. Update the device system to avoid text display errors caused by outdated system versions. Restore the app default settings if the interface layout is disordered.

Dark and light mode adaptation is abnormal

Turn off and re-enable the system automatic mode switching function. Manually switch the app dark and light mode multiple times for adaptation calibration. Confirm that no third-party screen color modification tools are running on the device.
