The Closest Thing to a Retrograde Tracker Device

Nobody manufactures a physical device for this. What people searching for a retrograde tracker device actually want is something that updates live and doesn't require checking a static list that might already be out of date.

What a Real Tracker Needs to Show

A useful tracker answers four questions at a glance: is the planet currently direct, retrograde, or stationary right at a turning point; what exact degree and zodiac sign is it sitting in right now; when does the next station happen; and where are the edges of the shadow period on either side. A calendar with three dates printed on it answers none of these with any precision.

Sky Today builds this from real orbital calculations rather than a lookup table, tracking every planet from the Sun through Pluto, not just Mercury. The live orbit view shows where each body actually sits on the zodiac at this moment, and the retrograde tracking flags stations as they happen instead of after the fact. None of it requires a birth chart, since this is about the current sky, not a personal one.

If the goal is a device, the closest real equivalent is the phone already in your pocket, pointed at something that recalculates in real time instead of guessing from a printed schedule.
