BillTracker app not downloading on new phone

I recently switched to the new iphone 15 pro max - I tried downloading the BillTracker app by SnapTap and it is telling me it is no longer available in the app store. I had all my bill tracking information on there, I have used it for years. How can I get my information from there!?

Contact the developer. We can't help you with an issue like this.
