No software is perfect. The apps we create at are no exception unfortunately. So if you found an error in one of the apps that we created, here's how you can report it in a way that allows us to fix the issue.

Before reporting an issue, please follow this guide to check if the issue also shows up in a browser. If it does, it's most likely an issue that you need to fix on your website.

Screenshots & Screen Recordings

The best thing you can do is record a video of you triggering the error in the app. Clearly show all the steps that lead up to the error and the actual error. Most new Android and iOS devices have a screen recording feature built in already, so usually you don't even need to download an app to record it. Or, if you have a second device, you can film the screen that way.

If you can't create a screen recording, screenshots are the next best thing. They're only a static image, so we might need more clarification if reproducing the error is not obvious for us.

Steps to Reproduce the Issue

Please provide detailed step by step instructions that will cause the issue to appear. Please be extremely detailed and make sure these instructions make the issue appear every time. Without being able to reproduce the issue, it's almost impossible to fix it.

Here is an example for such steps to reproduce an imaginary issue:

  1. Open the app
  2. Click the login button in the drawer menu
  3. Click the register button
  4. Now the issue appears: the app only shows a blank page

Device Information

Please name a device that you saw the issue on, e.g. iPhone 14 Pro Max or Samsung Galaxy S22. Also mention which operating system version was the device running e.g. Android 13 or iOS 16.1.

Diagnostic Information

The app has a built-in feature to report additional diagnostic information (internal error and warning messages) that are very useful to investigate certain app issues. To send the diagnostics, follow these steps:

  1. Make the error appear in the app.
  2. Shake your device in a large up and down motion for roughly 20 seconds. The delay is set so high to avoid using this feature accidentally.
  3. After roughly 20 seconds you will see this message at the bottom of the screen. Click the button in the message. If you don't see it yet, continue shaking. A screenshot of the app with a small message with a button popping up at the bottom of the screen.
  4. Describe the error you are seeing and click "Report Error". A screenshot of the dialog that pops up where you can describe the error..

Hi, I'm Jan! I created 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 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.
