Gear Design is great in designing involute gears from scratch. Application includes a CAD interface in front end where users can assess designed gears visually with their finger gestures (zoom, rotate, twist etc.). Users can easily generate STL data of the CAD model and export them via Email (Two step action: first generate data and then export via Email). Tooth bending strength analysis calculator is included with multiple sharing options, including a pdf file.

Verdict

The call

The clearest difference is price: Quantum Computing at Free against Gear Design's $2.99. Quantum Computing also leads on update cadence (daily vs every 12 months) and device support (4 vs 1). Gear Design's advantage is in-app purchases (none vs 1) and iOS requirement (9.3 vs 17.0). On ads there is nothing between them.
