About this app

Gainfully is the AI-powered fitness app that actually knows you.

Most fitness apps track your workouts. Gainfully understands them. Your AI personal trainer learns your lifts, your history, and your goals, so every recommendation feels like it comes from a coach who has been watching your progress from day one.

STRENGTH TRACKING
Log every set and rep, and watch your estimated 1RM update in real time. Gainfully tracks your strength level, celebrates every PR, and keeps your full training history so nothing gets lost.

AI PERSONAL TRAINER
Ask anything, get answers grounded in your actual data. The AI coach knows what you lifted last week, how your progression looks, and what you need to focus on next.

TRAINING PROGRAMS
Choose from ready-made programs or let the AI build one tailored to your schedule, experience level, and goals. Whether you train for strength, hypertrophy, or cardio, Gainfully has a plan for you.

CARDIO TRACKING
Log runs, cycling, and outdoor sessions alongside your strength training for a complete picture of your fitness.

1,000+ EXERCISES
A full exercise library with GIF guides, muscle group filters, and built-in tracking. Find the right exercise, learn it correctly, and track every session.

MUSCLE BALANCE
See which muscle groups you are training and which you are neglecting, so you can build a balanced, injury-free body.

AVAILABLE IN 6 LANGUAGES
Gainfully is fully translated into English, Danish, German, French, Spanish, and Brazilian Portuguese.

Train smarter. Progress faster. Get Gainfully.
AI personal trainer that knows your lifts, your history and your goals.
