VALDA

VALDA is the workout app the fitness industry should have built years ago. Proper workout logging, intelligent programme management, a watch companion that's faster than any phone, and the only cycle tracking that actually connects to your training. Workout Logging That Respects Your Time Log sets with full support for weight, reps, tempo notation, RPE, set types (warmup, dropset, AMRAP, backoff, rest-pause), cardio distance and duration, and supersets. Personal records are detected automatically across seven categories — max weight, max reps, max volume, estimated 1RM, max distance, best pace, and max duration. Every PR triggers a celebration on your wrist. The Programme Parser Find a programme anywhere — Reddit, a coach, a PDF, a forum post. Copy the text. Paste it into VALDA. The entire programme is structured in seconds: exercises, sets, reps, RPE targets, rest periods, tempo notation, percentage-based loading, deload weeks, phase names. What used to take twenty minutes of manual entry takes about ten seconds. Supports 5/3/1, GZCL, PHUL, PPL, wave loading, and virtually any format. Five imports per month on Pro. Watch Companion Your phone stays in your bag. The Apple Watch app sends your current set to your wrist — exercise name, target reps, suggested weight. Adjust if needed. Tap complete. Next set loads instantly. Rest timer, heart rate monitoring, and exercise swaps all work from your wrist. It is the fastest workout logging experience available. ValdaFLEX — Smart Exercise Alternatives Machine taken? Tap the exercise, see alternatives ranked by muscle group overlap and movement pattern similarity. One tap to swap. Mid-session, no disruption, no muscles missed. ValdaFREYA — Free Forever Menstrual cycle tracking that actually connects to your training.
