Volja - AI nutrition tracking meets science-based workout scoring

Volja is a fitness app that does two things no other app does: logs meals instantly using AI (just describe what you ate) and scores your workouts using EMG-based muscle activation research. Instead of just counting sets and reps, Volja shows you exactly which muscle groups are undertrained and where you're at risk for imbalance injuries. Built by a solo developer over 6 months. Free 30-day trial.
