Hi @joshmeth30,
I like to categorize and enter manual transactions on the fly via mobile too… And I’ve been using the Mobile App that I’ve setup with Google’s AppSheet.
And I’ve setup something similar to Mobile App for Tiller with AppSheet. And the best part is it is free to use and anyone can build apps with low-code option available here. But, obviously it has its limitations, but still works for the most part of it.
