AuroraCue: Aurora Forecast

AuroraCue answers two questions every aurora chaser has: is it worth going out tonight, and how do I get a real photo of it on my phone? KNOW WHEN TO GO AuroraCue reads NOAA's Space Weather Prediction Center feed and weighs the strongest activity during your dark hours against your geomagnetic latitude, not just your map latitude. Much of North America and Europe sits several degrees closer to the aurora's reach than a plain latitude check would suggest. The home screen paints tonight's sky to match the verdict, tells you the Kp your spot needs, and charts the next 24 hours so you can see which ones reach you. It also works out when the sky is actually dark where you are and how bright the moon will be, because a bright moon can wash out a faint display. GET THE SHOT A bright aurora photo needs the shutter open for seconds, and a phone camera caps out well short of that in a single frame. AuroraCue locks exposure and ISO, takes several frames in a row, and merges them into one brighter image, right on the device. Tripod mode uses longer, dimmer frames for the cleanest result. Handheld mode uses shorter, brighter frames and lines each one up automatically to cancel out hand shake. ALERTS THAT KNOW YOUR SKY With AuroraCue Pro, you don't have to keep checking. AuroraCue sends a push in the evening when NOAA's forecast for your dark hours reaches the Kp your location needs, and another when the live one-minute reading gets there while it's dark where you are. Nothing arrives in daylight, and nothing for a storm that won't reach you. Where the aurora is up most clear nights anyway, it waits for a genuinely strong display instead of buzzing you every evening. Pro also adds a live map of NOAA's aurora oval with you marked on it, refreshed every five minutes; the full three-day Kp outlook; and saving and sharing your stacked photos. FREE WITHOUT ADS Tonight's forecast and the whole camera, stacked result included, cost nothing and show no ads. AuroraCue Pro costs $29.99 a year, and the first week of the yearly plan is free; monthly is $4.99. Payment is charged to your Apple account, and subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel them in your Apple account settings. YOUR DATA STAYS PUT The forecast runs on your location right on the device. Only if you turn on an alert does AuroraCue's server keep a rounded version, about 100 km, plus a push token; switching alerts off erases both. Frames are merged locally and never uploaded. There is no account and no sign-in. WHAT TO EXPECT The visibility estimate is an honest approximation from published aurora-oval figures, not a guarantee. Photo results depend on how dark and still the sky is, and a steady surface helps even in handheld mode.
