Connecting Telegram to the web account

Sign in at expensegauge.com, tap your name at the top right and choose Connect Telegram - one tap links the two. That item only shows while the account is not linked yet, so if you cannot see it, you are already connected. Afterwards the bot and the web app show exactly the same receipts. After that you can send the bot a photo of a receipt, and it is read and filed just as in the web app. Replies from support reach you there too.
