How fast can you react?
Wait for green, tap, and find your five-round average. Speed Up turns a quick reaction test into a competition you can play alone or with a friend.
FIVE CLEAN REACTION ROUNDS
See your average and each round's time in milliseconds. Early taps and interrupted runs do not become ranked scores or earn a badge.
FIVE ANIMAL BADGES
Earn Falcon, Cheetah, Cat, Fox, or Owl based on your five-round average. See your collection and the targets for your next badge. Animal names are playful game titles, not scientific comparisons with animals.
SHARE THE RESULT YOU EARNED
Preview a card with your real badge and average time. Share it through your device's share sheet when you want to challenge a friend. You choose whether and where to post.
FIVE-ROUND ONLINE DUELS
Connect Game Center and face another player.…

No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured

speed-upWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
