Showing Jupiter and Saturn in the sky together.

Apps on our smartphones get a bad rap for wasting our time, and deservedly.

It’s true that most are either harmful or neutral, or a distraction, or a minor convenience.

One set of apps that are genuinely something that exist only because we have “computers in our pockets” are apps1 like Sky Guide, which have this magical ability to tell me which stars are in the sky, highlight them for me as I move my phone around, and display helpful connecting lines, the ecliptic, etc

I can’t believe I paid the price of a cup of coffee2 for something that’s mine to use forever, and that works so well and is delightful every single time I use it!
