In order to get reviews for your app in the Apple App Store or the Google Play Store you will need to get the links to your apps. Here is how you can do that:
Apple App Store:
You can click on this link to search for the link to your app in the Apple App Store:
https://linkmaker.itunes.apple.com/en-us
Just do a search for your app, select your app and it will take you to the page for your app. Copy the URL for this page and use it to create the button on the written reviews page in the settings of your SoTellUs Dashboard.
Google Play Store:
Do a Google search with your App Name + Google Play. Click on the search result for your app in the Google Play store. Copy the URL from the top of the browser and use it to create the button on the written reviews page in the settings of your SoTellUs Dashboard.
