Thank for you interest! The two jumps in 2019 were from marketing promotions. We offered a significant discount (I believe 50%) to our registered userbase during the summer and then again for Thanksgiving/Black Friday.
Those promotions didn't seem to have a lasting effect. Does another promotion explain the most recent spike?
We believe Covid is likely affecting our usage. We provide invoicing services, less sales means less traffic.
We're about to release a new version of our app built with @FlutterDev. We've been able to build web/mobile/desktop apps with one codebase.
