Coach.AI - Gym Workout Planner

Coach.AI is a mobile app for people who train with weights, in the gym or at home with dumbbells, from first-time gym-goers to experienced lifters. It builds a path of linked training programs and runs it week by week like a personal coach: it sets the weight for every set from what the athlete actually lifted, adds load or reps when they are ready, and rebuilds the next week from their logs and feedback. Live on Google Play and the App Store in 7 languages, with a Premium subscription (monthly or yearly).

Coach.AI is live on Google Play and the App Store (version 2.0.67), available in 175 countries and territories and in 7 languages.

Primary customer: people aged 18 to 45 who train with weights, in the gym or at home with dumbbells. Two segments: first-time gym-goers who need to know what to do and how much to lift, and experienced lifters stuck on a plateau who want a structured program that progresses by itself. Since the app was renamed "Gym Workout Planner", 55% of people who build a plan train in a gym and 80% train with weights. About a third want to lose weight, which widens the market beyond bodybuilding. Focus markets are where people pay for subscriptions: the US, UK, Western Europe, Canada and Australia.

Most people who start strength training don't know what to do in the gym or how much weight to lift. "How much weight should I lift?" is the most common beginner question. About half of new gym-goers quit by week 19, roughly one in ten still trains a year later, and nearly half fear being judged. A personal trainer solves this but costs about $55 an hour. Workout apps are either logs that leave the planning to the user, or generators of daily workouts without a long-term plan. The opportunity: affordable, real coaching for the millions of people who already pay for gyms and fitness apps.

Coach.AI is a personal strength coach in the phone. After a one-minute questionnaire (goal, level, equipment, days per week) it builds a path of linked training programs and runs it week by week:
- it sets the weight for every set from what the athlete actually lifted, with a warm-up ladder;
- it raises load or reps when the athlete is ready, with deloads and test days built into the path;
- it rebuilds each next week from logged sets, effort, soreness, sleep and missed days;
- an AI coach answers in plain words: swap an exercise when the barbell is taken, fix a sore week, plan a comeback.
A rules engine guarantees safe, sound programming; the language model explains and adapts.

Apps: Fitbod (AI-generated daily workouts, $79.99 to $95.99 a year), Alpha Progression (programs with automatic progression, $79.99 a year), JEFIT (workout log and plan library, $69.99 a year), Hevy (workout log, $23.99 a year), Planfit, Strong.
Alternatives outside apps: a personal trainer (about $55 an hour), free programs from YouTube and PDFs, or training without a plan.

- A full path, not daily workouts: linked programs with stages, deloads and test days, planned months ahead.
- The weight for every set comes from the athlete's own logs, so beginners never guess.
- A coach you can talk to during the session, backed by a rules engine, not a generic chatbot.
- Built for first-time gym-goers too: none of the main competitors' store pages speaks to gym anxiety.
- Works offline in basement gyms; a workout player in the Android notification shade.
- 7 languages from day one and regional prices in 175 countries and territories.
- Very low cost base: one founder with an AI-assisted workflow and about $0.90 AI cost per subscriber a year.

Revenue: Premium subscription at $19.99 a month or $99.99 a year (US price; regional prices in 175 countries and territories), with a 7-day free trial and promo offers. The first week of the plan is free.
Costs: very low and mostly variable. AI cost is about $0.90 a year per yearly subscriber, hosting runs on Firebase, store commission is 15%. There is no payroll: I build the product myself with an AI-assisted workflow. The main planned cost is user acquisition.

Model: freemium subscription. Users get a real plan and the first week free, then upgrade to Premium to continue the program and generate the next weeks.
Sales channels: Google Play and the App Store (in-app purchase), organic store search in 9 store locales, an 8-language website with free tools and a blog, social media. Next: Meta and search ads in paying markets.
Key metrics tracked every week: store page to install, sign-up to plan, plan to first workout, plan to trial, trial to paid, return on day 7 and day 28, cost per paying user.

$50,000 to $100,000 for 12 months of growth:
- 60% paid acquisition: Meta and search ads in the US, UK and Western Europe, tested in small steps and scaled where a paying user pays back;
- 20% content: ad videos and creatives, store video previews and screenshots, native-speaker copy;
- 10% product: infrastructure and scaling costs, contractors for device testing;
- 10% legal: incorporating the company for the round, the investment agreement, moving the app and its rights into the company.
12-month goals: 1,000 paying subscribers and a repeatable paid channel in two paying markets.

Equity in the company that will own Coach.AI, on terms we agree together (a SAFE or a direct share purchase). The company will be incorporated for the round as a Ukrainian LLC or an EU or US entity, whichever suits the investor, and the app, store accounts, domain and code will be transferred to it. The investor joins at the earliest stage, with a finished product live on both stores and almost all of the money going into growth.

- Retention: fitness apps lose most users in the first weeks. Mitigation: first-week features are already shipped (first gym day scheduling, reminders with the day's plan, next-time weights after every workout) and measured every week.
- Acquisition cost in paying markets may be higher than planned. Mitigation: small tests per channel before scaling; budget goes only where a paying user pays back.
- Strong competitors with large budgets. Mitigation: a clear niche (real coaching and first-time gym-goers) and a very low cost base.
- Single founder. Mitigation: documented codebase with automated tests; the product budget covers contractors when needed.
