Is there an accurate way to track conversion data for offline advertising campaigns? I.e. the number of downloads of a mobile App that is promoted on coffee sleeves?

To add clarity to this question, let’s say I am promoting a Mobile App and the objective is to get people to download my App. If I were to run an online advertisement campaign, there are software and tools available (i.e. Google Analytics) for me to use that allows me to precisely track the conversion data i.e. the number of people who downloaded a Mobile App as a result of the online ad, etc.

However, when it comes to the offline advertisement world, how can I track the conversion data? For example, if I were to promote a Mobile App on a coffee sleeve, how can I track the number of conversions that resulted from advertising on such offline mediums? Is it even possible?
