We regularly help customers - that already have an app - switch to an app created by us. There can be many reasons for this. The most common ones we hear are:
It's always great if you let us know what your reason is, so we can make sure that we can fulfill your expectations.
To publish your app as an update, the new app needs to have the same digital signature as the old app. For that, you will need the following information:
You will be able to upload the key information in our app publishing guides.
If you'd rather sign your app yourself (which is more complicated), see our guide on signing app bundles yourself. You can skip the section about generating keys, as you need to use your existing ones.
We also support updating/replacing existing iOS apps. You don't need anything specific in advance here except access to your Apple Developer account where the app is published.
Our app publishing guides will lead you through all the necessary steps to update your app.
There's a few features that most web browsers support but our apps don't yet. In this article we explain what those features are and why we don't support them yet.
Here's a quick guide on how to install an Android app before publishing it in the Google Play Store or another Android app store.
This short guide explains the process of inviting the webtoapp.design team into an Apple Developer account so we can upload your iOS app.
Hi, I'm Jan! I created webtoapp.design in 2019 while studying computer science in university. A lot has changed since then - not only have I graduated, but it's also no longer just me running webtoapp.design. We've grown to a global, fully remote team and have gathered lots of experience around app development and app publishing. We've created and published hundreds of apps in the app stores, where they've been downloaded hundreds of thousands of times.
