About
Brain and Senses is ten short, honest challenges for reasoning, memory, reaction time, attention, colour, fine detail and hearing.
Every challenge has Entry, Regular and Hard levels. Each one starts with a short demo and an unscored practice round, then a scored round with a clear progress bar. Your basic score is always free, with its limits explained.
THE CHALLENGES
• IQ Style Reasoning: find the rule in a grid of shapes
• Reaction Time: respond the moment the panel lights up
• Memory: repeat a sequence of lit cells
• Attention: press only for the right symbol
• Spatial Reasoning: mentally rotate a shape
• Spot the Difference: find every change between two scenes
• Color Discrimination: find the shape hidden in coloured dots
• Hearing Perception: which interval holds a quiet tone?
• Visual Gap: which way does the gap in the ring point?
• Multitasking: react to a symbol while remembering a flash
TRACK YOUR PROGRESS
Results are saved on your iPhone, with stats, a score guide and history for every level. No account needed.
FREE, WITH ADS
Every test and score is free. The free version shows banner ads and a short ad after each test, never during one.
PREMIUM
One upgrade covers all ten tests: detailed breakdowns for every result, your full history and stats, a progress trend, and no ads. Choose Premium Lifetime (pay once) or Premium Monthly. Want to try it first? Watch two short ads for a free 1-Day Pass.
HONEST BY DESIGN
These are challenges for curiosity and practice. They are not medical, psychological, vision or hearing assessments, they cannot diagnose any condition, and the reasoning challenge does not produce an IQ number. If you have concerns about your thinking, memory, mood, attention, vision or hearing, please talk to a doctor, a mental health professional or a clinic.
Payment is charged to your Apple Account. Premium Monthly renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings.
