Chrome: We've probably all made a regrettable, impulsive buy before. What if there was an app that automatically put such purchases into perspective? There is, and it's called the Dictionary of Numbers.
The Chrome extension turns numbers on web pages into relatable, easy-to-understand terms. As Reddit user Saturated_Wombat points out, this can be useful not just for interesting factual knowledge ("oh, I have as many followers as the capital city of a country I never heard of"), but also to possibly curb spending.
When shopping online, Dictionary of Numbers will convert dollar amounts to comparable stats: you could buy a beginner bike instead of that portable gaming system, that pair of sneakers is equal to the average household's daily income, etc. It's just a very visual reminder of the opportunity cost of buying anything.
