An AI-powered fitness coaching app that adapts its coaching style, workouts, and reminders to each user — built on Flutter, Supabase, and Gemma AI.



Sign Up/Login & Account Management — Users can join TrainBuddy AI in seconds using email, phone number, or social login, with a smooth password reset flow if they ever get locked out. Full account management lets users update personal details, manage connected devices, and control their data — all without needing support tickets. A frictionless entry point means fewer drop-offs before users even reach their first workout.
Coaching Personality Selection — Instead of one generic AI voice, users choose between Friendly, Motivational, Tough, or Calm coaching styles that shape every interaction — from daily check-ins to workout feedback. This turns TrainBuddy AI from "just another fitness app" into a coach that actually matches how the user wants to be pushed. The result is higher emotional buy-in, better adherence, and users who feel understood rather than managed.

Quick Workouts (5/10/15/20 min) — On days when a full session isn't realistic, users can instantly generate a 5, 10, 15, or 20-minute workout tailored to whatever time they have. There's no manual planning or scrolling through irrelevant routines — just a tap and a ready-to-go session. This keeps consistency high even on the busiest days, which is often the difference between a user who sticks around and one who churns after week two.
Injury-Aware Coaching — Users can flag discomfort, pain, or physical limitations directly in the app, and the AI responds by recommending safer, lower-impact exercise alternatives instead of pushing through a generic plan. This reduces the risk of the app recommending something that worsens an existing issue, which is a major trust-breaker in fitness apps. It also signals to users that the coaching is adaptive and genuinely looking out for them, not just running a fixed script.

Hydration Tracking + Smart Reminders — Users log their water intake throughout the day and receive smart, context-aware reminders nudging them to stay on track with their personalized hydration goal. This extends engagement well beyond the workout itself, giving users a reason to open the app multiple times a day. Over time, it also feeds into the AI's broader picture of user wellness, making recovery and readiness recommendations more accurate.
Calendar Integration & Schedule-Aware AI — By connecting their calendar, users let the AI see exactly how much free time they actually have on a given day — and generate workouts that fit into that window automatically. No more manually adjusting workout length or skipping sessions because "there wasn't enough time." It removes one of the biggest excuses for missed workouts and keeps the coaching genuinely responsive to real life, not just a fixed schedule.

Admin Dashboard — Operators get a real-time view into total users, active users, new signups, revenue, AI usage, and workout activity — all from a single screen. This isn't just a vanity metrics panel; it's the operational backbone for understanding what's working, where users are dropping off, and how the AI layer is being used at scale. It gives founders and teams the visibility needed to make fast, informed product and business decisions.

Subscription Management — Admins can manage plans, pricing tiers, and cancellations directly from the dashboard, without needing engineering support for routine changes. This keeps monetization flexible — pricing experiments, promotional plans, or tier adjustments can be rolled out quickly. It also gives full visibility into active subscriptions and churn, which is essential for running a sustainable subscription-based fitness product.
