Weirdly enough, both websites use this exact same quote: "This means you'll need to make an API (application programming interface). It's how all your friendly apps talk to each other."

Either plagiarism was involved, or there's some underlying library that's the same for both, or they both hired the same company to build their MVP ;)

HowMuchToMakeAnApp is by "Commite, a digital studio specialized in driving ideas from inception to launch" based out of "Seville, San Francisco & New York".

BuildMyMVP is made by "ProductDone a digital studio based in Auckland, New Zealand".

If you do a search on the second sentence: "It's how all your friendly apps talk to each other." You'll find at least 10 other cost calculator websites that all use that exact sentence to explain the term API. It also shows how flooded the web is with sites like this.

Nice find.
