The field of interest of the AP-S encompasses: antennas, including analysis, design, development, measurement, and testing; radiation, propagation, and the interaction of electromagnetic waves with discrete and continuous media; and applications and systems pertinent to antennas, propagation, and sensing, such as applied optics, millimeter- and sub-millimeter-wave techniques, antenna signal processing and control, radio astronomy, and propagation and radiation aspects of terrestrial and space-based communication, including wireless, mobile, satellite, and telecommunications. This year’s technical program includes a wide range of technical sessions, workshops, and short courses, as well as numerous exhibits. It also has a number of activities dedicated specifically to students and young professionals. This event is the premier international forum for the exchange of ideas on state-of-the-art research in antennas and propagation and radio science. Through a range of technical and social activities, it provides the opportunity to interact with the world's leading experts in antennas and propagation and radio science from academia, industry, and government.

Verdict
The clearest difference is update cadence: SPIE Conferences at every 3 weeks against APS/URSI's every 6 months. APS/URSI's advantage is iOS requirement (10.0 vs 14.0). On price, ads, in-app purchases and device support there is nothing between them.
