Research demonstrates that app-based ADHD support solutions face systematic abandonment due to context switching costs, implementation friction, and executive function barriers. Email-only interventions eliminate these obstacles while maintaining therapeutic efficacy.

Context switching—the cognitive cost of moving between different applications or tasks—reduces productivity by 40% in general populations. ADHD individuals experience disproportionate impact due to:
Traditional app-based support requires repeated context switches:
| User Action | App-Based | Email-Only |
|---|---|---|
| Receive notification | Notification → App Switch | Email arrives (already open) |
| Complete daily check-in | Email → App → Form → Return | Reply to email (same context) |
| Request support | Remember app → Find app → Open → Wait for load → Navigate | Hit reply (0 cognitive steps) |
| View progress | Open app → Wait → Find section | Coach Hype emails summary |
Conclusion: Each app interaction requires 3-5 context switches. Email-only maintains single context throughout intervention.
