DETERMINE FLOW VELOCITY SmartPIV enables you to determine flow velocity within a PIV setup (particle imaging velocimetry). The expected experimental setup of the PIV System consists of a flow channel and a laser illuminated current enriched with particles. In this setup, SmartPIV replaces the traditional camera and analysis software. VIVID VISUALIZATION VIA VELOCITY VECTORS Current analysis results are graphically displayed via velocity vectors, allowing for an easy retracing of a current's development. SIMPLE, MOBILE AND CONVENIENT In contrast to conventional PIV systems, SmartPIV is low-cost and more intuitive in its application. ABOUT US We are a team of three students and two professors developing this application for hands-on training in the domain of thermodynamics at universities and beyond.

Verdict

The call

The clearest difference is rating: SmartPIV at 5.0 against Vector Field's 4.5. SmartPIV also leads on iOS requirement (13.0 vs 15.0). Vector Field's advantage is update cadence (every 3 months vs every 7 months) and device support (4 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
