+
+## 13. Competitive Landscape (Extended)
+
+### Tiimo (primary competitor)
+- iPhone App of the Year 2025, 3M+ downloads, ~$200K/month revenue, ~500K active users
+- Pricing: $12/month or $54/year (iOS), cheaper via web ($42/year)
+- Had a lifetime option — removed it, community backlash was significant
+- iOS and web only. No Android (as of September 2025). No native desktop app (web app cannot sync calendars or offer dictation).
+- Cloud-dependent. No voice transcription as a core feature.
+- Aggressive review prompts (3 prompts in 5 minutes reported by reviewers)
+- Strengths: visual colour-coded timelines, AI co-planner, no-guilt design philosophy, NHS certification
+- Weaknesses: slow animations, confusing UX concepts ("activity vs routine"), reported data loss issues
+- B2B pivot underway — projects B2B to reach one-third of total revenue within two years
+
+### Structured
+- Clean visual daily planner across iOS, Android, Mac, and web
+- Lifetime purchase option at ~£52
+- Android and web versions lag far behind iOS, iCloud sync unreliable
+- Not designed specifically for neurodivergent users
+
+### Goblin.tools
+- Beloved AI task breakdown ("Magic ToDo") — free on web, low-cost app purchase
+- Collection of single-task utilities, not a planner
+- Community favourite for one-time purchase model
+
+### Llama Life
+- Excellent timeboxing with finish-time visibility (combats time blindness)
+- No calendar integration, no free tier, very small team
+
+### Focusmate
+- Dominates body doubling — 274 five-star Trustpilot reviews
+- Web-only, not a task manager
+
+### Focus Bear
+- Desktop-first (rare) — locks computer until morning routines complete, blocks distracting sites
+- Australia-based, designed specifically for ADHD/autism
+
+### Super Productivity
+- Open-source, local-first, runs on Windows/Mac/Linux
+- Not originally designed for neurodivergent users
+
+### Lunatask
+- Tasks, habits, calendar, mood tracking, journalling with end-to-end encryption on desktop
+- Privacy-focused, small user base
+
+### Kon's advantages over the entire field
+| Kon | The field |
+|---|---|
+| Cross-platform desktop + mobile (Tauri) | Almost all competitors are mobile-first or web-only |
+| Voice as primary input method | No mature competitor integrates voice into a full planning system |
+| Local-first, offline-capable | Only open-source tools and tiny startups offer this |
+| Lifetime licence | Only Structured offers one-time purchase; rest are subscription |
+| Research-backed neurodivergent design | Most competitors bolt on ADHD features as an afterthought |
+
+### The four underserved dimensions
+1. **Platform:** No polished, purpose-built desktop ADHD app exists.
+2. **Input method:** No mature tool offers voice as the primary input integrated into a full planning system.
+3. **Architecture:** Privacy-conscious and offline-first users served only by open-source tools and tiny startups.
+4. **Pricing:** Only Structured offers lifetime. Subscription fatigue is extreme in this demographic.
+
+Kon addresses all four simultaneously. No current competitor does.
