A Telegram Mini App instead of a website and an app
Telegram has more than 900 million users, and a Mini App opens for them with no install and no sign-up. That is why a Telegram Mini App often converts better than a mobile website: the user is already authenticated, and payments and notifications are built into the messenger. We explain how a Mini App differs from a bot and a website in what is a Telegram Mini App.
A Mini App almost always works together with a Telegram bot: the bot brings users in, reminds them and brings them back, while the app provides a convenient interface. An example of this combination is the coffee chain case study.
