Client Check-in Summariser for Fitness Coaches

Import your clients' weekly check-in answers and get a short summary per client plus a draft reply in your voice, so check-in day takes less time.

Economics

Pricing example
$15/month for up to 40 clients
Daily math
40 coaches x $15/month = $600/month, about $20/day.
Target if you hit the daily math
Target: $600 / month at 40 subscribers

Audience and urgency

Audience: Online personal trainers, nutrition coaches and hybrid gym coaches with 10-60 remote clients.

Urgency: Coaches collect weekly check-ins (weight, sleep, adherence, notes) through forms, then spend hours reading and replying. Replies get shorter and more generic as the client list grows.

MVP scope

  • ✓ Import check-ins by CSV from Google Forms or Typeform exports, or paste text per client
  • ✓ Per-client summary: changes since last week, wins, and concerns flagged by the coach's own rules (e.g. sleep under a set number of hours)
  • ✓ Draft reply in the coach's tone based on saved example replies; the coach edits and copies it
  • ✓ Simple trend chart per client from numeric answers
  • ✓ Stripe subscription; client data deletable at any time

Omitted features

  • - Do NOT give medical, injury or diet-prescription advice; flag items for the coach to handle
  • - Do NOT message clients automatically
  • - Do NOT build workout programming or a client-facing app

One-shot master prompt

Build a "Check-in Summariser" web app for online fitness coaches in React with Tailwind CSS, Supabase and a serverless LLM endpoint.
Core requirements:
1. Clients list and CSV import from Google Forms / Typeform exports: map columns to client email, date, and question fields (numeric or text). Also allow pasting a single check-in.
2. Coach rules: e.g. "flag if sleep < 6", "flag if adherence < 70", "flag if text mentions pain or injury". Rules run in code before the LLM call.
3. Per check-in, generate a JSON summary (changes vs previous week, wins, flags) and a draft reply in the coach's tone, using 3 example replies the coach saves. The prompt must say not to give medical or diet-prescription advice and to leave flagged health issues to the coach.
4. Client page with a trend chart for numeric fields and the history of summaries and replies (copy-to-clipboard; no automatic sending).
5. Stripe Billing ($15/month, up to 40 clients) and a "delete client data" button that removes all of that client's rows.
