Hello @user1612 and we are happy to see you with us! Welcome to Elfsight Community 
Unfortunately, at the moment, there is no option to integrate our widgets with a mobile app. Please accept my sincere apologies 
We totally understand why you’d want that and agree that this feature could be a great addition to our product.
We already have such a request on our Wishlist. Please vote for this feature to get a notification upon its release here - Install a widget to a mobile app.
Feel free to leave a comment there or any insights you have as it helps us improve our apps. As soon as the feature you voted for is released, you will receive a notification from us
