Entering expenses on the spot using a mobile device can be convenient. One of the challenges is finding apps that focus on making this efficient. Here are some options. See also:

Apps with CSV export
The general workflow here is that every so often you manually initiate a CSV export from the app. Typically the app starts up a temporary HTTP server and you can fetch the data to your main machine with curl. Then, with suitable CSV rules, either run hledger reports directly from the CSV file, or convert it/import the new transactions into a more permanent journal file. A script or Makefile to automate this can be helpful.
