What we ship

**Core features (MVP)**

• Training journal: pad-rounds, sparring rounds, clinch sessions, technique notes (photo/video clips), trainer voice-notes → Claude parses → structured log
• Fight-prep checklist: at 12/8/4/2/1 weeks pre-fight — cardio plan, weight-cut target, technique priorities, mental check
• Gym directory + reviews: TH map with filter (city, weekly/monthly/walk-in price, English-speaking trainers, ring experience, fight promotion)
• Gym-swap log: "Trained at Sitsongpeenong June, moved to Tiger Phuket July" — portable across gyms
• Weight-cut planner: current weight → target → fight date → daily macro recommendations

**Primary user flow**

1. Sign up (email or Apple) → select experience level (beginner / amateur / fighter)

2. Post-session — 1-minute voice note → Claude structures it

3. Before TH trip — pick gym from directory (5-10% booking commission)

4. Pro upgrade after 4+ weeks logged or fight-prep mode

**What it looks like**

• **Landing**: hero "Train smarter — your Muay Thai journal that tracks like Strava" + interactive TH gym map + sample fight-prep timeline
• **Main app screen**: weekly schedule with pad-round/sparring/clinch counts + next-fight countdown widget
• **Gym directory**: map view + filter sidebar + reviews (verified "I trained here" badge)

**MVP build plan (13 days)**

• Day 1-3: backend (Session/Fight/Gym/Review models), Strava OAuth
• Day 4-6: voice-to-structured-log pipeline (Whisper → Claude), training analytics
• Day 7-9: gym directory CRUD + map (seed top-50 TH gyms from Reddit r/MuayThai)
• Day 10-13: fight-prep mode with weekly emails, landing, deploy + post on r/MuayThai

Reasoning

SIG-th-muay-thai-training-journal cites Angela Chang (athlete-fighter) who manually prints and sells a paper journal — strongest signal a digital tool is absent. SIG-th-muaythai-gym-swap-directory confirms: expat tourists pick gyms via Reddit + word-of-mouth. TH = world's Muay Thai capital (~100K expats/year come to train in Phuket/CM/Pattaya); $500-3000/mo paid spend = high disposable income. Stack ideal: Cloudflare PWA + Railway + Strava integration + voice-to-text. **medium-high competitive pressure** — Hevy/Strong exist for weightlifting but don't cover muay-thai specifics; gym-directory muaythaicitizen.com is weak.

Quick competitive read

• **Hevy / Strong / Stronger by the Day** — weightlifting-first, no rounds/clinch/pad counts.
• **Strava** — cardio + cycling, nothing combat-sport.
• **muaythaicitizen.com** — TH gym directory, bad UX, no booking, no English filter.
• **Reddit r/MuayThai** — community-driven, no structured directory.
• **white space**: muay-thai-specific journal + integrated gym directory + fight-prep mode — competitors with traction = 0-1.

Initial pricing hypothesis

Free — basic journal (1 week), gym directory read-only. Pro — $9/mo (~299 THB) or $59/year for unlimited journal + Strava sync + fight-prep mode + voice-to-structured-log. Premium for serious fighters — $19/mo with personalized weekly Claude reviews. Gym booking 5-10% commission. 99-299 THB for Thais + $9 USD for expats.

Distribution hypothesis

1) Reddit r/MuayThai posts (50K subs, direct audience); 2) Instagram micro-influencers with muay-thai vlogs (Phuket-based foreign fighters, 20-100K followers); 3) Partnership with top-30 gyms in Phuket/CM/Pattaya — reception QR → free month Pro for guests; 4) SEO "muay thai journal app", "best muay thai gym phuket beginner" (programmatic SEO city/level); 5) TikTok/YouTube "my Phuket muay thai camp diary" — direct product association.
