Review momentum
56/100
faster than 60% of Weather apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Stargazing Forecast & Planner
Cloud, humidity, wind, moonlight and twilight, distilled into one number. Star Index tells you whether tonight is a go for stargazing, 0 to 100, before you drive anywhere.
STAR INDEX (0-100)
Cloud cover is broken down by altitude layer and combined with humidity, wind speed, moon phase and twilight timing. Hourly and 7-day outlooks let you plan ahead. Seeing (atmospheric steadiness) and transparency are scored separately, so you can tell whether tonight favors planets or faint deep-sky targets.
DEEP-SKY CATALOG
All 110 Messier objects plus major NGC targets, each with its best viewing window worked out from twilight end and moonrise/moonset for your location. Planet and moon rise/set times, direction and altitude at a glance.
NEVER MISS A SHOWER
Get a viewing-conditions score for 8 major meteor showers (Quadrantids, Perseids, Geminids and more), with a push notification as the peak approaches. Eclipses and planetary oppositions are on a built-in calendar.
WIDGETS
Home screen and Lock Screen widgets keep tonight's Star Index visible without opening the app.
ON-DEVICE AI (supported devices)
On iOS 26 devices with on-device intelligence, Star Index writes a plain-language read of tonight's conditions. Unsupported devices fall back to a rule-based summary automatically.
PRIVATE
Location is used only to forecast your local sky. No account, no data collection, no ads.
PREMIUM (one-time purchase, not a subscription)
Unlock multiple saved locations, the full Messier catalog, photography windows and the 7-day outlook with a single purchase.
Stop guessing from a generic weather app. Star Index tells you if tonight is worth the drive.
