Dějiny Prahy jsou spjaté i s jejím německým obyvatelstvem a jeho kulturou. SAMSA tě zavede na místa, jež nesou stopu této „německé Prahy“ – jsou spojená s činností německy mluvících architektů, výtvarných umělců, literátů, hudebníků, spolků, škol a dalších institucí. U každého místa appka nabízí německý text se základním popisem, informacemi k jeho dějinám a roli v kulturním životě, a několik současných i historických fotografií. Výklad stojí na ověřených zdrojích, ale nezahltí tě. Objevuj s mobilem v ruce pozapomenutou součást dějin města! Aplikace vznikla v rámci společného projektu Shromáždění německých spolků v ČR a studentů i učitelů germanistiky na Filozofické fakultě Univerzity Karlovy. Počet hesel bude průběžně rozšiřován.

Verdict
The clearest difference is in-app purchases: Samsa at none against Thunderstand's 1. Samsa also leads on iOS requirement (12.0 vs 15.0). Thunderstand's advantage is update cadence (weekly vs every 16 months). On price, ads and device support there is nothing between them.
