A one-button timing game for iPhone.
How long is a second?
No clock, no countdown, just you and your nerve. Get close and the next target comes. Miss, and it's over. Give it a try: how long do you think a second is?
PRESS AND HOLD
IN THE APP, TARGETS MOVE EVERY LEVEL
01.000→02.400→04.900→06.900→…
Every run brings new targets, and the margins tighten as you climb.
DAILY CHALLENGE
One challenge a day.
The same targets for every player, every day. Three runs to set your best, then share a spoiler-free result with your friends.
DUELS IN MESSAGES
Settle it in the chat.
Send a challenge from any conversation. You both play the same targets in the same order, one run each, and the bubble shows who won. Play it safe, or go for glory.
ARCADE
How far can you go?
Every level tightens the margins. Miss, and a single revive gives you one more chance. Chase your best of the week, and your all-time record.
SKINS
Pick your instrument.
Play on the free Laboratory panel, or unlock Nixie, with orange tubes in walnut, and Coin-Op, with red LEDs in gloss black. Try any skin for an hour first.
Free, with ads
No ads for your first three days. After that, a one-off Remove Ads purchase turns them off for good. Skins are sold separately, and purchases work with Family Sharing.
No accounts, no sign-in, no tracking. Your scores stay on your phone, and duels travel only through Messages.
