You&#x27;ve answered your own question: there&#x27;s no <i>need</i>, you have no <i>problem to solve</i> by writing an app. Usually the problem itself dictates half the technology choices for you, and the rest are filled in by using what you already know. In your case though, you have no <i>reason</i> to write an app. So the only answer that makes sense is &quot;none&quot;.
