We just released the beta version of Costflow Hub. In this beta version, the workflow we support is Telegram + Beancount + Dropbox.
That means you can create Beancount entries right on your Telegram apps, no matter the device is Mac, PC, iPhone or Android phone.
Then the formatted entries will be synced to your ledger file on Dropbox.
Join now to get a free trial for 60 days. Get started here:

Costflow might be the simplest product to keep a Beancount ledger on mobile.
