It's very easy: Think about your app like a full-screen browser. Everything will work and look like your web app/website. All the changes you have made to your website / web app will be applied to your iOS & Android apps immediately. Therefore, app updates are often not required for content changes. For the app binaries and app source codes themselves (Android/iOS), the latest version of our app template is used during setup. The WeSetupYourWebViewApp fee is a one-time setup fee and does not include a fee to get one or multiple new setup(s) with (a) more recent version(s) of the app template at any time if desired. Nevertheless, an upgrade service (new app template version + manual reconfiguration by us) can be ordered in individual cases for a fee (lower than the original fee) and by separate arrangement. Alternatively, we are happy to provide the latest version of the app template codebase for self-setup free of charge upon request (voluntary service of us, not part of the scope of delivery). Although, from time to time, we provide free upgrades (including manual adaptations to the existing code base of the customers); this is done voluntarily by us and is not part of the paid services. In these cases, we contact the customers from our side. BTW: Often, our apps do not require maintenance upgrades at all. :-) Please check out our Terms and Conditions, too.
