About

SmartPIV

This application allows users to determine flow velocity in a PIV setup, replacing traditional camera and analysis software. It visually displays current analysis results through velocity vectors for easy understanding of flow development. Designed to be simple, mobile, and convenient, it offers a low-cost and intuitive alternative for hands-on training.

Highlights
  • Determine flow velocity in PIV setups
  • Visualize flow with velocity vectors
  • Replaces traditional camera and analysis software
  • Low-cost and intuitive application
  • Mobile and convenient for hands-on training

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.

Experience the hidden world of particles Quantum is a real-time particle life sandbox for exploring emergent motion, artificial physics, and complex systems. Build fields with up to 10,000 particles, tune how classes attract or repel each other, and watch simple rules turn into flowing structures, swarms, or chaotic patterns. Why Quantum stands out: - Real-time particle simulation with four interacting particle classes. - Seamless 2D fields and perspective 3D volumes with touch rotation. - Rule editor for custom attraction and repulsion matrices. - Temperature, viscosity, solid/fluid edge behavior, and force tools. - Black hole and white hole tools for live interaction. - Save and load fields, rule sets, and color schemes. - P3 color support and vivid visual presets for generative art. Use Quantum as a physics toy, creative sandbox, teaching aid, or generative art lab. It is built for people who enjoy science, cellular automata, n-body systems, chaos, and beautiful simulations.

Verdict

The call

The clearest difference is in-app purchases: SmartPIV at none against Quantum's 6. SmartPIV also leads on iOS requirement (13.0 vs 26.0). Quantum's advantage is update cadence (every 5 weeks vs every 7 months) and ratings volume (152 vs 2). On price, rating, ads and device support there is nothing between them.

Both are free to download. Quantum sells 3 one-off in-app purchases. SmartPIV asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

SmartPIV holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Quantum has 152 ratings behind it against 2, so its average is the more settled of the two.

UpkeepUpdate frequency

SmartPIV ships an update every 7 months, Quantum every 5 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
