Sanshin invites you to a cyber-mystical universe between architecture, spirituality and technology. It offers an interactive and immersive experience around holographic fragments of digitised Korean architecture. These architectural models are 3D scans made during a two-months-long mission around the Korean Peninsula. Supported by the Hanyang University and University of Paris-Est, the Franco-Korean mission sought to study the supernatural representations in Korean architecture of the Goryeo Period (10-14th centuries). The “augmented touch” functionality allows users to touch and interact with virtual models visualised in physical space. Holographic ghosted visualisations increase the sensation of an overlay that is both mystical and digital. This app is the result of an experiment undertaken as part of the doctoral research of Mete Kutlu in collaboration with the developer Theuns Botha. The experiment sought to combine augmented reality and photogrammetry to innovate in digital scenography, mediation and humanities. As part of a series of experiments baptised as Dream Pixels, it was realised with the support of Cristiana Mazzoni, senior expert at Comet Lab and director of AUSser research lab at the Paris-Belleville School of Architecture.

Verdict
The clearest difference is in-app purchases: Sanshin at none against Flow's 5. Flow's advantage is update cadence (every 6 days vs every 32 months). On price, ads, device support and iOS requirement there is nothing between them.
