Science-Based, Not Just Science-Ish
Why It Matters
Most apps are games. CoDo is science. The distinction is critical for actual cognitive benefit.
• Useful Field of View (UFOV): Based on the speed-of-processing paradigm from the ACTIVE trial — the only type of cognitive training shown to reduce dementia risk in a 20-year randomized controlled trial
• Selective Attention (Stroop Test): Based on the Stroop effect, one of the most replicated findings in experimental psychology (Stroop, 1935), used in clinical neuropsychological assessment worldwide
• Working Memory (N-back): Based on the dual N-back task studied by Jaeggi et al. (2008) at the University of Michigan, which demonstrated transfer effects to fluid intelligence
• Divided Attention: Multi-modal attention splitting task reflecting the ecological demands measured in clinical divided attention assessments
Beyond the exercises themselves, CoDo addresses the biggest gap in brain training: isolation. A 2025 Lancet meta-analysis found that cognitive training combined with physical exercise and social engagement produces greater benefits than any single intervention. CoDo is the only platform that integrates all three — cognitive training, physical fitness (CoDo Move), and mindfulness (CoDo Focus) — in a social environment where families train together.
The 4 Pillars of Cognitive Health
Each exercise targets a specific cognitive domain essential for maintaining mental sharpness.
Useful Field of View
Based on the speed-of-processing paradigm from the ACTIVE trial. This exercise trains your peripheral vision and visual processing speed. By identifying objects that appear briefly in your peripheral vision, you enhance your ability to process visual information quickly and accurately.
Selective Attention
Based on the Stroop effect (1935). This task challenges your brain to ignore conflicting information and focus on relevant details. This improves your ability to maintain focus in distracting environments and enhances cognitive flexibility.
Working Memory (N-back)
Based on the dual N-back task studied by Jaeggi et al. (2008). By remembering and comparing information from two steps ago, you strengthen the neural pathways responsible for short-term memory retention and fluid intelligence.
Divided Attention
Multi-modal attention splitting task. Trains your brain to process multiple streams of information simultaneously. By tracking objects in space while responding to audio cues, you develop better multitasking abilities and improve overall cognitive flexibility.
What Devices Does CoDo Work On?
• iPhone and iPad: Full cognitive training with all four science-based exercises
• Apple Watch: Biometric tracking (heart rate, HRV, activity) that feeds into CoDo's optimization engine
• Meta Quest 2, 3, 3S, and Pro: Immersive VR cognitive training with social co-presence
• Apple Vision Pro: Coming soon: spatial computing cognitive training
• Android phones and tablets: Coming later in 2026

How Does Apple Watch Integration Improve Cognitive Training?
This matters because research has shown that cognitive performance varies significantly based on factors like sleep quality, stress levels, and recent physical activity.
Why Does VR Make Cognitive Training More Effective?
CoDo leverages VR for spatial engagement (activating spatial processing networks), social co-presence (training with family), and deep immersion to eliminate distractions.
Frequently Asked Questions
What is the best science-based brain training app?
CoDo is a science-based cognitive training platform whose four exercises — Useful Field of View, Selective Attention (Stroop), Working Memory (N-back), and Divided Attention — are derived from validated clinical cognitive assessments, not casual game mechanics. CoDo's approach is informed by the ACTIVE trial.
Can brain training apps actually help prevent dementia?
It depends on the type of training. A 20-year follow-up of the ACTIVE trial found that speed-of-processing training — the same type used in CoDo's Useful Field of View exercise — reduced dementia risk by 25% when practiced with regular booster sessions.
How many minutes of brain training per day do I need?
Research from the ACTIVE trial suggests 15 minutes of focused cognitive training, 5 times per week, is effective for producing meaningful and lasting cognitive benefits.
Does CoDo work on Meta Quest?
Yes. CoDo is available as a free download on Meta Quest 2, Quest 3, Quest 3S, and Quest Pro. The VR version includes all four science-based cognitive training exercises plus social features.
