SetFlow

Turn the workouts you find into workouts you can follow. SetFlow brings a workout timer, gym log and AI planner together. Create a routine with AI, import one from an image or video, or build it yourself. Then time your sets and rest, log reps and weight, and review your progress in one place. TURN VIDEOS INTO WORKOUTS Upload a workout video or paste a supported video link. SetFlow uses AI to identify demonstrated exercises and read instructions shown in the video, turning them into an editable workout. Review the exercises, sets and details, make your changes, and save the routine before you train. IMPORT WORKOUTS FROM IMAGES Turn a screenshot or photo of a written routine or training plan into an editable workout. Review and adjust the result instead of rebuilding the routine from scratch. TIME YOUR SETS AND REST Run timed, rep-based, interval and mixed workouts. Customize work and rest periods for individual sets, switch between elapsed and remaining time, and choose a focused timer or full workout view. Haptics, audio cues and voice coaching help you follow each transition. Optional pickup detection helps manage work and rest transitions. LOG FROM YOUR LOCK SCREEN Enter reps and weight directly from your Lock Screen on supported iOS devices. Keep your current interval visible with Live Activities and Dynamic Island while you train. PLAN WITH AI OR BUILD YOUR OWN Create a structured workout around your goals, schedule, equipment and training preferences. Use the AI workout planner or guided workout wizard, then review and edit the result. Prefer to build manually? Choose your exercises and customize sets, reps, weight, notes, work time and rest time. TRACK YOUR TRAINING Record reps, weight and notes for each set. Review previous sets and exercise history, track training volume and personal records, and see your progress over time. Save routines as templates and review a summary after each session. FIND THE RIGHT EXERCISES Explore 1,000+ exercises with instructions and movement animations. Filter by equipment or body part, and start your workout from any exercise or set. From strength training and bodybuilding to home workouts, HIIT, Tabata, circuits, EMOM and AMRAP, SetFlow helps you turn workout ideas into structured training you can follow and log.

Verdict
The clearest difference is update cadence: Interval at every 6 days against SetFlow's every 2 weeks. SetFlow's advantage is iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
