About the app
gAIns is a gym tracker built for powerlifters and strength athletes who want data without the friction. The core UX principle is zero typing — workouts are logged with minimal input, using AI to handle the heavy lifting of data entry.
The standout feature is an AI Coach powered by Anthropic Claude, which provides personalised training advice, programme adjustments, and feedback based on your actual training history — not generic templates.
Additional features include an analytics dashboard, custom program builder, personal record tracking via the Epley formula, macro and hydration logging, push notifications, offline mode, a social leaderboard, and three subscription tiers via Stripe.
