Sky Guide

iOS astronomy app that moved from a one-time purchase to a free-to-download, subscription-tiered model

As of 1 September 2026, Sky Guide is free to use. An iOS stargazing app from Fifth Star Labs that now offers a free base app with two paid subscription upgrades, Plus and Pro. Softwr lists it under Education. Sky Guide is made by Fifth Star Labs, available on iOS.

Overview

What Sky Guide does

Sky Guide overlays labelled stars, planets, satellites and deep-sky objects on a live camera or gyroscope-driven sky view, with light pollution forecasting, meteor shower prediction and a large object catalogue in its higher tiers. It began years ago as a straightforward one-time paid app and has since moved to a free download with in-app subscription upgrades. The distinguishing fact is that shift itself. Sky Guide Plus adds a larger star and satellite catalogue and light pollution and meteor forecasting for a low monthly or annual fee, while Sky Guide Pro adds an enormous deep-sky object catalogue, exoplanet data and extreme zoom for a higher fee. That business model change from one-time purchase to subscription is a common complaint among users who bought earlier versions outright and now see ongoing features gated behind a recurring charge. Buyers are iOS-only stargazers who want strong light pollution and meteor forecasting alongside the sky map itself, a feature set SkySafari and Star Walk 2 do not emphasise as heavily. The trade-off against SkySafari is platform, since Sky Guide is iOS-only where SkySafari also covers Android and desktop, and against Star Walk 2 the trade-off is price, since Sky Guide Pro costs considerably more.

What people use it for

  • An iOS stargazer who wants light pollution forecasting to plan a dark-sky observing trip
  • Someone tracking meteor showers and wanting a forecast of viewing conditions
  • A user who wants extreme zoom into deep-sky objects without owning a telescope
  • A buyer comparing subscription astronomy apps on iOS specifically, rather than cross-platform tools

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Sky Guide.

  • It is iOS-only, unlike SkySafari which also covers Android and desktop.
  • It has moved from one-time purchase to a subscription model, and long-time users who paid once for earlier versions have criticised the change publicly.
  • Pro tier pricing is high relative to Star Walk 2 for broadly similar core stargazing functionality.
  • It has no telescope control, unlike SkySafari Plus and Pro, which limits it to naked-eye and camera-based observing.
  • Its relationship to other apps under the same distribution platform is not clearly documented, which makes long-term support commitments harder to assess.
