Southwire's voltage drop calculator will help you determine the proper wire size for an electrical circuit based on the voltage drop and current carrying capacity of an electrical circuit. Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run. When sizing conductors, calculations limits wire size to voltage drop and NEC ampacity. Southwire's Voltage Drop Calculator is designed for applications using AWG and KCMIL sizes only.
BinMaster Sensor App

The BinMaster Sensor App allows for the quick and easy setup of BinMaster sensors that are equipped with Bluetooth. With the use of a smartphone or tablet, level sensors can be configured for the specific vessel size, material type, and process conditions. The app securely and automatically saves and backs up all sensor settings and data. If any adjustments are required, simply log into the device settings, and make the necessary updates. With wireless operation via the app, data transmission is continuous and compatible with IIoT and Industry 4.0 standards.

Verdict
The clearest difference is update cadence: Southwire® Voltage Drop Calc at every 2 months against BinMaster Sensor App's every 9 months. BinMaster Sensor App's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
