Common questions
Do I need an app store listing?+
Usually not. Progressive web apps install straight from the browser and cost a fraction of native app development. If you need a Play Store listing we can do that too.
Can the app connect to my POS or website?+
Yes — we build the website, POS and app as one connected system so orders, customers and stock stay in sync.
