My favorite iOS app so far is Arctic.

My library has something called discovery kits. They’re large bags with everything you would need to try out a specific activity. There’s all sorts of things, including metal detectors, sewing, astronomy, photography, microscopes, vacuums, anatomy, bike repair, circuits, and so many more. The thing I love about these is that they’re not just a few books about the topic, they really have everything you need. The photography kit has a camera, astronomy has a telescope, sewing has a sewing and embroidery machine, etc.

If that’s the case, be sure to get Thunder too.

Edit: Just remembered Liftoff and Nemmy.

Have you found anything new since the last update?
