Amana paints the sky above you right now, from your exact time, place, and the sun's position, then invites you outside to meet the real one. - The sky, right now Time, location, sun elevation, and today's actual cloud cover come together as a procedurally rendered sky - a blue noon, a burning sunset, or a night sky - right on your device. Clear or cloudy, today's weather shows up as it really is. - Capture it. Name it. Meet the real sky outside, then give it a color, a name, and one line. Your photo is never handed to an AI - the name comes from extracted color, time, and weather instead. Works offline. - A growing collection Every named sky joins your collection, one frame at a time. - The view from space See how the sky you just looked up at appears from orbit, alongside true-color Himawari satellite imagery (Japan Meteorological Agency / NOAA-NESDIS / CIRA, Colorado State University). - Widgets & StandBy (Amana Pro) See today's sky without opening the app - on your Home Screen, Lock Screen, or in StandBy. ¥300/month, or ¥1,500/year with a 7-day free trial. - Privacy Amana collects no information that identifies you personally. Photos stay on your device. Location is only ever used as a rough area for weather - your precise location is never sent anywhere. - Subscription Amana Pro (JPY 300/month or JPY 1,500/year with a 7-day free trial) is an auto-renewable subscription. It renews automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel it in Settings > Apple ID > Subscriptions on your device.
