Common questions
Where are my scores stored?
Challenge times and Free Play best scores are stored locally on your iPhone. Brain Reaction does not upload them to an account or server.
How do I reset my best times?
Use the reset option on the Brain Reaction home screen. You can also remove all locally stored game information by deleting the app.
Does the app require an account or internet connection?
No. Brain Reaction has no account, sign-in, advertisements, or in-app purchases, and its four games can be played offline.
What should I include in a bug report?
Tell us which trial and mode you were using, what you expected to happen, and what happened instead. A screenshot is helpful when the issue is visual.
