• Toast pop-ups provide simple feedback or instructions. They appear for a short period of time before disappearing and convey whether an action initiated by the user or an app succeeded or failed. Toasts should be about one line, and should never exceed 3 lines in any language. They should also only be used to inform users of relatively minor information. If the user needs a make a choice or be warned of a serious issue (such as a threat to their health, data, or privacy), then use a popup.
