Hello all. This forum has been really helpful. I have a tight turnaround right now and need to make sure that launch in the app stores will offer a perfect product. Right now, everything I see in the builder is pixel perfect, but the PWA and preview render a lot of screen really disorganized. This is with groups, snapping, etc. I have a lot of simple elements like text and shapes…Does anyone know if I can trust my builder to reflect what the app store version will look like, or do I need to design with the PWA preview in mind? The latter is difficult without options to alt hover and assure that elements are equidistant, etc. ---

I’ve learnt something in 2 years of usage of Adalo. If you see a perfect web app preview/PWA, it does not means it performs the same on the native side. So i always deeply test my native versions of apps and then work from there, not on PWA anymore. There are many layout/design differences and “troubles” you have to keep in mind switching from PWA to native android or iOS ---

Thank you! Have you found what things look like in your builder are indicative of the native app at all? Or is nothing a sure thing? ---

Definitely not a sure thing. Even some positional problems happen depending on phone. I’m currently testing on an iPhone 8 Plus, 11 & 11 Pro and the 11 Pro is the most consistent, if I switch the previewer to the 11 Pro Max resolution, this indicates what is likely shown on the 8 Plus and 11. Things such as positional issues and components that behave incorrectly. Takes some back and fourth for sure, they’re just way too many mobile sizes out there 🙂 ---
