English (United States)Aug 12, 2026 eclipse planner in the classic Pro app.
Identify stars, planets & constellations in a realistic 3D sky map
Stellarium Plus - Star Map answers "astronomy app" in one glance: full-bleed sky renders with thumbnail-legible captions like "Point your phone to spot planets". Mobile Obs Pro Astronomy opens on a date-scoped eclipse planner for Aug 12, 2026, with dense UI shrunk inside small device frames. Neither listing surfaces a single visible trust cue.
Scanned screenshots4 a · 4 b
Only the first 4 screenshots from each side are sent to the AI. These are what users see in App Store and Google Play search results, so they carry most of the conversion weight.
App A
App B
Value Proposition
B leadsFirst screenshot sells "2026 Solar Eclipse Planner"; the general sky-map benefit only appears by screenshot 4, after the eclipse pair.
"The most realistic sky at any time" on screenshot 1, reinforced by planets, constellations and satellites across screenshots 2 to 4.
Clarity
B leadsCaptions name real features, but screenshots 3 and 4 repeat a clipped subhead line ("live as you explore the sky.") over tiny in-frame UI.
Full-bleed shots with verb captions: "Learn the constellations" over a labelled Ursa Major figure, "See satellites pass overhead" over an ISS track.
Emotional Hook
B leadsScreenshot 2 is a paragraph of contact times and obscuration figures; no observer, no scene, captions name modules rather than the night out.
Screenshot 1's dusk fisheye with a house and lawn at 11:04 reads as a real backyard, but captions state capabilities, not feelings.
Trust Signals
TiedThe NASA SRTM elevation-data claim sits in the description only; no badge, download count, or citation appears on any of the four screenshots.
No testimonials, awards, or compliance badges; "The most realistic sky at any time" is an unsupported superlative rather than an attestable cue.
Reviews for Mobile Obs Pro Astronomy cluster around the 4.x rewrite: many long-time users report removed or reset features, frequent crashes, and a live view that no longer aligns with the real sky, set against strong praise for the depth of astronomical data. Reviews for Stellarium Plus - Star Map are dominated by praise for the star map itself and for observation planning with telescope and mount control, with a smaller recurring thread about compass and sensor calibration. Both apps draw repeated comments that the paid version is worth the money.

MediumMobile Obs Pro Astronomy leads with a dated event hook, "Aug 12, 2026 eclipse planner", and a paid-tier housekeeping message, then reveals its real claim deep in the description: NASA SRTM terrain and a topographic horizon instead of a flat one. Stellarium Plus - Star Map leads with the category's default job, "Identify stars, planets & constellations", pointed at the sky in seconds. The mismatch is one of altitude: one listing buries a planning-precision claim under version admin, the other repeats the category's most contested promise with total coherence.

Gap
Mobile Obs Pro Astronomy leads with a single dated event and paid-version admin ("Already bought this app? Reinstall it"), while Stellarium Plus - Star Map leads with the durable category job of identifying what is overhead right now.
Opportunity
The topographic horizon claim, "Other apps assume a flat horizon", is a planning-accuracy position Stellarium Plus - Star Map never contests, so it can be moved from paragraph seven into the first impression where search browsers actually decide.
Risk
The first two lines of Mobile Obs Pro Astronomy spend their attention on an eclipse date and on which version a buyer already owns, so a searcher for "astronomy app" sees an event utility plus a licensing notice rather than a reason to prefer it, and the listing also decays into irrelevance the day after Aug 12, 2026.
Strategic advantage
Terrain-accurate rise and set times, aurora alerts, GOES solar flare data, and ISS passes speak to astrophotographers who plan a shoot around a ridge line, a buying motive that a point-and-identify planetarium does not serve.
Missed opportunity
Neither listing claims trip-planning certainty, the promise that a user will not drive to a site and find the target behind a hill or the sky unusable. Both describe what is in the sky; neither promises the observing session succeeds.

Stellarium Plus - Star Map
Slight lead
Stellarium Plus - Star Map sits at 11 and Mobile Obs Pro Astronomy at 12 for astronomy app, and that one-place lead is earned on conversion, not on relevance. Mobile Obs Pro Astronomy is the closer keyword match of the two, yet its listing spends its opening line on a dated event while Stellarium Plus - Star Map answers the search in a single glance.
Why it wins
Stellarium Plus - Star Map states the category's core job, "Identify stars, planets & constellations", and backs it with full-bleed sky renders whose captions stay legible at thumbnail size, with reviews dominated by praise for the map and for telescope and mount control. Mobile Obs Pro Astronomy carries the stronger astronomy app wording but reaches the same searcher alongside a review thread about crashes, reset features and a misaligned live view since the 4.x rewrite.
Biggest opportunity
The title already carries the astronomy term, so the real gain for astronomy app searchers sits in the short description, which currently leads with an eclipse date and version admin while the terrain-accurate claim, NASA SRTM horizons behind rise and set times, stays buried deep in the description where no searcher reads it.
Next priority
The remaining test is whether a durable, horizon-led line such as "Astronomy app with a real 3D horizon: rise times from your own skyline" (70 characters) holds astronomy app traffic better than a hook that expires on Aug 12, 2026, with the eclipse moved into the first description paragraph. Run it alongside the live-view calibration fix reviewers describe as 'off by 30-40°', since a promise of observing-session certainty only converts if the sky view lands where it should.
