How do I play? Colour spreads across the black screen — swipe it away with your fingers before it fills the screen. Use two fingers when it gets fast.
The screen slides down near the bottom edge. That's iOS Reachability. Turn it off in Settings → Accessibility → Touch → Reachability.
Does the app collect my data? No. Maintain collects nothing and works fully offline. See our Privacy Policy.
