Discover Stars and Planets: Live Map Shows Current Constellations in Full Detail
For a "night sky forecast" search, Light Pollution Map - Dark Sky actually holds the most on-intent data of the two, the "Darkness Starts in: 04:07:35 (8:10PM)" strip with cloud cover, KP index and a meteor shower calendar, but it sits in small orange text on uncaptioned raw UI screens dated "November 2017". Sky Tonight - Star Gazer Guide carries a caption banner on every frame, "The most realistic sky at any time" and "See satellites pass overhead", over rendered twilight horizons that make the payoff readable in a thumbnail. Neither listing shows a testimonial, award or compliance cue, so trust is the one even row.

Value Proposition
B leadsLight Pollution Map - Dark Sky buries its forecast payoff, "Darkness Starts in", cloud 56%, KP 1.00, in a small bottom strip.
Sky Tonight - Star Gazer Guide states the benefit in banner type: "The most realistic sky at any time" over a dusk horizon.
Clarity
B leadsFeatures are visible but unlabelled: the Light-to-Dark map legend, "Moon Info For Today", and Orionids/Leonids rows carry no captions.
Every frame names one function in plain words: "Point your phone to spot planets", "Learn the constellations", plus a Visible passes time table.
Emotional Hook
B leadsAll four frames are unretouched app UI: toolbar, world map, a 2017 calendar grid and a moon data panel, with no observing scene.
Rendered twilight horizons with treelines and mountains set the mood, but captions name capabilities, not the stargazer's outcome.
Trust Signals
TiedNo badges, testimonials or download counts; the 2017 dates on the calendar and moon screens read as an aged capture set.
Sky Tonight - Star Gazer Guide shows no award, press quote, user-count or privacy badge across its four frames.
Reviews of Light Pollution Map - Dark Sky repeatedly praise it as a planning tool for finding dark-sky and astrophotography sites, while a recurring group of reviewers flags the Bortle key labelling (the swatch between 4 and 5 shown as 5.5) and the absence of a numeric Bortle value when tapping a location, plus objections to the annual subscription. Reviews of Sky Tonight - Star Gazer Guide praise its educational depth on stars, planets and celestial events and its easy interface, but a recurring set of reviewers describes ad frequency in the free version and confusion or billing issues around premium access. Both listings draw mostly positive sentiment, with the pain points in each concentrated on pricing mechanics and one specific data-display gap.

MediumLight Pollution Map - Dark Sky positions itself around location: where the sky is dark enough, framed as "the only app you need to master the night" for the self-described "hardcore astronomer". Sky Tonight - Star Gazer Guide positions itself around identification: what the objects overhead are right now, answering "What's that bright object in the sky?" for beginners and experienced stargazers alike. Against a "night sky forecast" query, one listing sells a place to go and the other sells an object to name, and neither leads with the timing verdict the query implies.

Gap
Light Pollution Map - Dark Sky leads with where to observe from, an accurate light pollution map and horizon safe radius, while Sky Tonight - Star Gazer Guide leads with what is overhead, a live map, AR overlay and object identification.
Opportunity
Nobody searching "night sky forecast" is asking what a star is called, so Light Pollution Map - Dark Sky can claim the conditions question, cloud cover, moon and darkness, that Sky Tonight - Star Gazer Guide only reaches through its Stargazing Index deep in the feature list.
Risk
The subtitle spends its strongest position on "more than 100 other astronomy tools", a breadth claim rather than an answer, so a forecast-intent searcher sees an app requiring exploration while Sky Tonight - Star Gazer Guide promises to "Instantly answer". Breadth-first framing tends to lose the quick-decision user even when the underlying cloud cover and aurora layers are exactly what was wanted.
Strategic advantage
The combination of light pollution map, cloud cover map and aurora overlay lets Light Pollution Map - Dark Sky own the go or no-go decision for astrophotographers and aurora chasers, buyers whose motive is avoiding a wasted drive rather than learning constellation names.
Missed opportunity
Neither listing sells multi-night planning, naming which upcoming night is worth the trip. Sky Tonight - Star Gazer Guide frames Time Machine and the Astronomy Calendar as exploration, and Light Pollution Map - Dark Sky frames its cloud data as a check before walking outside tonight, leaving "pick the best night this week" unclaimed.

Sky Tonight - Star Gazer Guide
Strong lead
Sky Tonight - Star Gazer Guide holds position 1 for night sky forecast while Light Pollution Map - Dark Sky sits at 12, and that gap reflects readability rather than data: Light Pollution Map - Dark Sky actually carries the more on-intent forecast content. The ranking is defensible on conversion clarity, not on forecast substance, which is where it is contestable.
Why it wins
Sky Tonight - Star Gazer Guide puts a caption banner on every frame and promises to "Instantly answer", so the payoff is legible in a thumbnail, and its short description leads with a live map rather than a tool count. Light Pollution Map - Dark Sky's "Darkness Starts in: 04:07:35" strip, cloud cover and KP index sit in small orange text on uncaptioned screens dated "November 2017", so the strongest forecast evidence in this matchup is the hardest to read.
Biggest opportunity
Light Pollution Map - Dark Sky owns the go or no-go decision a night sky forecast search implies, cloud cover plus aurora plus darkness timing, and neither listing yet claims picking which night this week is worth the drive.
Next priority
Test a conditions-led short description such as "Dark sky map, cloud cover & aurora: night sky forecast worth going out" (68 chars) against the current tool-count line, moving the 100-tools claim into the description body. In parallel, the night sky forecast payoff deserves a captioned lead screenshot of the darkness countdown, since reviewers already value the app as a planning tool.
