I created this bot for myself, and I wanted a quick and straightforward way to save expenses.
Messengers are very convenient. You can send messages from all platforms: iOS, Android, Web.
You even don't need to be online. If the message is not delivered, you can re-send it later.
Another great feature is that you can save shared expenses with your partners and friends.
Just create a new chat and add the bot to this chat!
Tags are handy when you are travelling.
You don't want to create new categories for expenses, but you want to know how much did you spend for your last holidays?
Just add tags to your message: "15.75 cafe #travel #portugal".
And you will be able to track all expenses with these tags in the future.
In the travel mode bot adds tags, specified by you, to every new expense.
Enable travel mode, go to holidays, and that's all!
