MEAX Coax
Read full descriptionHide full description
This is a companion app for performing high precision coaxility measurements of machine tools, typically between two opposing workhead spindles or a workhead spindle and a tool holder. The app guides the user through the complete measurement and evaluation process when using the high precision MEAX transmitter/detector sensors SM 201 and SR 201. Together, this simplifies the otherwise cumbersome and time consuming task to ensure that workhead spindle and tools are perfectly aligned, or to quickly check that a machine is still within tolerance after a crash. ---- Note: This app works only with the MEAX SM 201 and MEAX SR 201 ---- Key Features - Connected using Bluetooth®. Requires Bluetooth 4.0 - Intuitive user interface, all symbols and graphics – no text - Compensates for machine bed slant - Saves the measurement result and makes it possible to share it using standard functions Visit the website www.meax.com for more information on MEAX products and support on the app.

Verdict
The clearest difference is update cadence: Pre at every 7 months against MEAX Coax's every 29 months. MEAX Coax's advantage is iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.
