The MultiProtector app now makes monitoring, evaluating and protecting your pump even easier and more efficient. The app offers the following functions: - Read data directly from the MultiProtector device. This gives you access to the fault memory/counter, allows you to assess the current status of the pump and view the operating data. - Create a report in PDF format in no time and forward it directly to your customers if needed or use it for your own documentation. Additional functions (does not require a gateway): - Retrieve the data sheets for the installed NETSZCH MultiProtector, so that they are available quickly and paperless during maintenance and repair work in the plant. - Analyze the status of the pump via the LED blink code, set the blink code and get the current error displayed directly

Verdict
The clearest difference is in-app purchases: MultiProtector at none against Mechanical Engineer's 3. MultiProtector also leads on iOS requirement (12.2 vs 17.6). Mechanical Engineer's advantage is update cadence (every 2 months vs every 6 months). On price, ads and device support there is nothing between them.
