What should I look at tonight? Star Archive picks the objects your aperture can actually show under your site's sky. 1,272 objects are judged in advance, so you don't drive out and find nothing there. An app for visual astronomy — observing through a telescope or binoculars with your own eyes. Plan → observe → record, in one unbroken line. ■ One unbroken night · Plan — added objects settle into hour slots on their own; drag to rearrange. Rehearse the night on the chart before you leave. · Observing — step through objects, check them off, rate and write notes. Dictate by voice. · Records — enter the night's conditions once, then review by night or by object. Long-term plans spanning months, too. ■ Data and learning · 16,000+ objects and 2,400+ visual guides — how to find it and what each aperture shows. 4,600+ observing points to rate. · Lists such as Messier, Caldwell, Herschel 400 and 1001, plus your own lists and courses. · Star hopping with 126 routes; Messier marathon prep and a 110-object night. ■ Also Night mode (red screen, shake to toggle, automatic after sunset) · six themes · a 130,000-star chart · SkySafari and Stellarium link · sketch albums · eyepiece-view simulator · tonight's clouds and seeing · real-time planets · spreadsheets in and out, full backup · on a bigger screen at starnotearchive.com · Korean, English and Japanese. Free. No ads, no purchases. No account in the app; make a web account only if you want the website. Records stay on your phone; only what you send goes up to the web (site names visible only to you). With weather on, the forecast point's location is passed to the weather service. Made as a hobby by one observer.
