Introducing Sun Hydraulics’ "AmpSet Blue(TM)" app for configuration of Sun's Bluetooth Embedded Amplifiers. This new app is iOS compatible and fully optimized for Sun Hydraulics' electro-proportional cartridges. Configurability is now in the palm of your hand with an iPad or iPhone product using proven wireless Bluetooth technology while maintaining the controller's IP69K sealing. Sun’s AmpSet Blue will allow you to select and interact with individual embedded cartridge valve amplifiers within range of your iPhone or iPad, making on-site ‘tuning’ portable, quick and simple. On-screen graphics and smart prompts will guide the user through the straightforward configuration process that covers all typical parameters associated with proportional valves from command type to coil drive limits. The application also allows the user to save the configuration file or interrogate an unknown controller and send the information via the smart device-installed email client for safe backup or to allow further upload into new controllers as needed.

Verdict
The clearest difference is in-app purchases: AmpSet Blue at none against WelderCalc's 4. AmpSet Blue also leads on iOS requirement (8.0 vs 16.0). WelderCalc's advantage is update cadence (every 4 days vs every 2 months). On price, ads and device support there is nothing between them.
