Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
TopOpt
Explore structural engineering concepts with an interactive topology optimization tool. Design and visualize optimized structures in real-time by placing loads and supports. Supports advanced features like volume and stress constraints for detailed analysis.
- Real-time structure updates
- Minimum compliance optimization
- Compliant mechanisms design
- Local volume and stress constraints
- Robust formulation for design insensitivity
- STL export for 3D printing
- Interactive load and support placement

TopOpt is an interactive topology optimization app from the TopOpt group at the Technical University of Denmark (DTU). Place loads and supports, and the optimized structure appears and updates in real time while you edit. Two problem types: • Minimum compliance: the stiffest structure for a given amount of material • Compliant mechanisms: a force inverter and a gripper, with input and output ports and their springs Both can be extended with: • A local volume constraint for bone-like porous infill • A von Mises stress constraint, with the stress field shown on the design • The robust formulation, which makes the design insensitive to its members being made thinner or thicker Further features: • Presets: MBB beam, L-bracket, cantilever and femur, and force inverter and gripper for mechanisms • Up to six loads and three load cases, and scaled loads • Loads, supports and ports are moved by dragging their symbols, and loads and ports can be rotated • Passive solid and void regions, and flexible void regions that the optimization may move • Custom grid size, sharpness and filter radius • Export of the design as an STL file for 3D printing The same app runs on iPhone, iPad, macOS, Windows and Linux. A user guide with tutorials is available on the TopOpt homepage.

Verdict
The clearest difference is review sentiment: myHBC at 100% against TopOpt's 67%. myHBC also leads on update cadence (fortnightly vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.
