About TriFit
TriFit is a personalized weight-loss companion that turns structured training into real, lasting results.
Whether your goal is shedding pounds, building strength, or crossing a triathlon finish line, TriFit brings guided workouts, science-backed calorie planning, and live performance tracking together in one place. The app offers step-by-step plans across four disciplines — weightlifting, running, swimming, and triathlon — so beginners and seasoned athletes alike always know exactly what to do next.
A built-in calculator estimates your daily calorie needs and weight-loss timeline, while the training calendar keeps every session organized. Live GPS tracking, wearable sync, and progress analytics help you see how far you've come and what to tackle next.
TriFit is built by a small team of fitness enthusiasts and software engineers who believe training should be clear, encouraging, and honest. No gimmicks, no guesswork — just the tools you need to train smart, lose weight, and win.
