WHAT MUSEUM is an art and culture facility that exhibits invaluable artworks stored at Warehouse TERRADA by artists and collectors. We have used our unique insight as a warehousing company to explore what an art facility should be. The concept we arrived at was “opening our warehouse to offer viewers an opportunity to see art that is rarely open to the public.” The thoughts and intentions of the artists and those of the collectors and their treasured works are displayed concomitantly. We have created a venue to encounter such art. The name WHAT (WAREHOUSE OF ART TERRADA) suggests the cultural value that glows quietly within the walls of a warehouse, as we exhibit two-dimensional and three-dimensional artworks, architectural models, photographs, videos, literature, and installations. These diverse art forms are curated and exhibited in our museum from a perspective unlike any other that only a warehouse company can offer.

Verdict
The clearest difference is update cadence: E at every 2 weeks against WHAT MUSEUM's every 2 months. WHAT MUSEUM's advantage is iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
