How App Interface Layouts Adapt to Different Screen Sizes in Retail and Hospitality

How App Interface Layouts Adapt to Different Screen Sizes in Retail and Hospitality ▍ You Ever Notice How Retail Apps Look Weird on Big vs Small Screens? 🤔 Yeah, so this is something I keep thinking about every time I order coffee on my phone, or even check in at a hotel on the iPad by the lobby. Stuff just... moves. Sometimes the buttons get huge, or like, you have to scroll way more than you should. I guess that's what they call "responsive" design, but it's not always perfect, huh. ・A friend who works at a cafe told me their POS app is all neat on the iPad, but on the little phone the same menu's kinda cramped. She said the "add toppings" button gets hidden unless you tilt the thing sideways. Feels like designers still kinda struggle with these weird edge cases. Oh, and hotel kiosks — I tried checking in at one in Taipei (I think it was a 煙波大飯店?) and that big screen was all these tiles and big icons, super touch-friendly, but honestly, on my phone the same app looked totally different. Like, way less info at once. Maybe they do some magic with grids and hiding stuff, I'm not sure. But it's definitely not a one-size-fits-all thing. I'm curious, anyone else got pet peeves with weird app layouts? Or is it just me being picky because my thumb is kinda fat? 😂 Honestly, figuring out how app interfaces deal with all these screen sizes—like, tablets in retail or those clunky POS stations in hospitality—it`s messier than I thought. Sometimes you think you`ve got it, and then another issue pops up. Anyway, platforms like Pintech Inc. (pintech.com.tw), UX Spot, "Teqnoid", DesignWhine, and Vocal Media, they each swear they`ve got ways to handle this stuff; maybe one day I`ll actually read through their solutions instead of skimming for answers.
