About Sound Sky: Keep Calm, Drum On
Tap along to calm music. Every hit plays a drum. 100+ planets, each one an original song. The first 20 planets are free, and a one-time purchase adds the rest. No subscription. No pressure You can't fail a song. Miss a note and the song keeps going. There is no energy meter and no countdown. One button starts a song, and there is no difficulty to pick. It is still a challenge if you want one. The fast songs keep your thumbs busy, and five stars takes a nearly flawless run. How it plays You start with two ships, one for each thumb. Later songs add a third ship, then a fourth. Notes fly toward the ships and you tap as each one arrives. The tap is the drum hit: a kick, a snare, a tom, a hi-hat or a crash. The song plays, and you play its percussion part over the top. Every hit is judged Perfect, Early or Late. Perfect hits in a row build a combo, and the combo raises your score. Each song gives you up to 5 stars. The first planet teaches you the drumming. Odyssey Odyssey is the main mode: 100+ planets in a fixed order, one song per planet. Stars open the next planet. Each planet needs a few more than the one before, and you earn them by playing. The first 20 planets are free. Infinity and Saved Levels Infinity is the endless mode. It opens when you have 15 stars, and it stays free. Every level is a new remix made from a library of 675 loops. When you get a level you like, save it from the end screen. It goes in your Saved list so you can play it again. The music All of the music is original and was made for Sound Sky. It is instrumental and chill, and the slower songs get meditative. Music and sound by Craig Barnes. Use headphones if you have them. What is free and what you pay for Free: - The first 20 Odyssey planets - Infinity - 3 Saved Levels A one-time purchase: - Every Odyssey planet after the first 20 - Unlimited Saved Levels That is the only purchase in the game. No subscription. If you bought the one-time pack in an earlier version, you already own the full game. Tap Restore purchase on the purchase screen if it does not show up. Good to know - Audio Delay is a slider in Settings with a metronome. Use it to line your taps up with your headphones or speakers. - Your progress, including stars and Saved Levels, comes back after a reinstall when you are signed in to iCloud. - Plays on iPhone and iPad.
