Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Space in under a minute a day, free. Sera Pro adds journeys you play with your finger, like Moon Lab and Eclipse Window, plus Pro episodes and personal review.
Learn the universe in under a minute a day. Sera is a short audio episode about space, picked for your sky tonight, with a quick question afterwards to make it stick.
EVERY DAY, FREE
Daily episode: One short audio episode each day, chosen around what's happening above you: clear skies, a full or new Moon, an upcoming eclipse.
48 free episodes: A library of under-a-minute audio episodes across the Moon, the Solar System, Deep Sky and Observation. All 48 stay free.
Quick recall: Answer a short question after each episode, track your accuracy, and build a daily streak.
NASA, made short: The Hubble feed and NASA's Astronomy Picture of the Day, rewritten into two or three plain sentences, linked to related episodes.
3D Solar System: Rotate, zoom and tap any planet for its facts and related episodes.
Lunar calendar: Tonight's phase and illumination, the month ahead, the next four phases and upcoming eclipses with where they're visible.
Astrophotography: A score for tonight's shooting conditions based on moonlight and cloud cover, with a suggestion for what to shoot.
Built for the dark: A black, low-glare design that's easy on your night vision.
