Apps

A few small apps I'm building — for my kids, for the trail, for the fun of it. Most will be free. Here is the set, with more arriving as they ship.

Vier

Four in a row, two players on one device. Built for my son.

A caterpillar arcade game you steer with the Digital Crown.

A pocket navigator for hiking and orienteering: heading, distance, coordinates, marks.

Will the fly stay dry tonight? A night-rain verdict for campers.

Tell time by the sun: a solar dial for your wrist, built on Bogenzeit.

Your calendar in solar time: the events already on your iPhone, laid out along the Sun's arc in Bogenzeit.
