There is a browser-native cosmic compass listed on Product Hunt. It shows where the solar-system planets are in real time for your location and the current moment, and it uses your device’s sensors to guide a 3D arrow. If you want something broader, the closest direct options are Stellarium, a computer planetarium, and Star Walk, a mobile sky guide. Product Hunt also lists AvoMap, Shadowmap, PeakVisor and Maps & Dioramas AR as alternatives, but those are adjacent tools built for other jobs, not one-to-one replacements.

Which There this article covers

Product Hunt hosts more than one product named There. This article covers the cosmic compass that locates planets. It does not cover the unrelated timezone-management tool with the same name. If the product you are looking at handles time zones or meeting schedules, you are on the wrong listing.

What the There listing claims

The Product Hunt listing describes three things:

  • It shows real-time positions of solar-system planets based on your exact place and the current moment.
  • It uses your device’s sensors to guide a 3D arrow in real time.
  • It runs in the browser, with no installation and no account needed.

These are the listing’s own claims. No independent test has confirmed the precision of the sensor guidance or the accuracy of the planetary positions. The product website linked from the listing could not be read when this comparison was prepared, so pricing, browser compatibility, privacy handling, offline use and the calculation method are not established here. Check those details on the product site before relying on them.

Alternatives at a glance

The table below separates the two kinds of alternative. The first group is what Product Hunt lists under the alternatives heading. Those products do different jobs. The second group covers astronomy apps that overlap more directly with finding planets and the night sky.

Product What it is for, per its listing or store description Fit for locating planets Relationship to There
There Browser-native cosmic compass showing current planet positions using device sensors; no installation or account, per the Product Hunt listing Core purpose Subject of this article
AvoMap Animated 3D maps for events None; not a planet finder Adjacent mapping product
Shadowmap Interactive 3D maps for visualizing solar shadows worldwide Limited; covers sunlight, not planetary positions Adjacent, relevant only if sun direction is the question
PeakVisor 3D maps and peak identification None; outdoor terrain Adjacent, relevant to hiking rather than astronomy
Maps & Dioramas AR AR maps and dioramas None; playful AR mapping Adjacent, not a dedicated planetary compass
Stellarium Free, open-source computer planetarium software that simulates the sky, including planets, and supports telescope control Yes, with a much wider sky view Direct astronomy alternative
Star Walk Mobile sky guide with real-time celestial tracking and AR viewing; some features belong to Star Walk Plus, per the App Store listing Yes, with identification and AR features Direct astronomy alternative

Direct astronomy alternatives

These two products overlap most with what There does. They also do considerably more, so they suit a different kind of user.

Stellarium

Stellarium is free, open-source planetarium software for a computer. Its published description says it simulates the sky, includes the planets, and can control a telescope. It is the better choice if you want a full sky simulation, want to browse objects beyond the planets, or plan to connect a telescope. Because it is desktop software, it is not a quick, hold-up-your-phone orientation tool in the way the There listing describes.

Rank #2
Desktop Pilot - C172 Magnetic Compass for Flight Simulators
  • Built for Realism
  • Plug-and-Play Sim Integration

  • Perfect for Training & Immersion

Star Walk

Star Walk is a mobile sky guide. Its App Store listing describes real-time celestial tracking and AR viewing, with some features part of Star Walk Plus. It fits best when you want to point a phone at the sky and identify what you see. Check the subscription terms and current pricing in the App Store before you commit, because they can change.

Adjacent alternatives from Product Hunt

Product Hunt presents these four products as alternatives. Their stated purposes differ from locating planets, so treat them as neighbours in the mapping category rather than substitutes.

Shadowmap

Shadowmap offers interactive 3D maps that visualize solar shadows around the world. It becomes relevant only if your question is where the sun’s light falls on a given place and time. It answers a sunlight question, not a planetary one.

How to choose

  • You want planet direction for your current location, in a browser, with nothing to install: stay with There, and read its claims as the listing presents them.

  • You want a phone app to identify stars, planets and constellations, with AR: choose Star Walk, and check which features require a subscription.

  • You only want a playful AR map: Maps & Dioramas AR.
