Swim Structured

Your coach sends you a workout. You're standing on the pool deck. Now what? Swim Structured turns any coach-written swim set into a structured, device-ready workout in seconds. Paste the text, tap Parse, and every interval, with its stroke, effort, equipment, and the coach's exact cues, is ready to send to your Apple Watch or Garmin. BUILT FOR THE WAY COACHES ACTUALLY WRITE Coaches don't write in JSON. They write "4 X 50 @ Kickboard Flutter, finish last 15M hard kicking!" Swim Structured reads that. It handles the shorthand real swimmers use: send-offs, rest intervals, equipment callouts, round multipliers, mixed-stroke intervals, and the little notes that actually make a set work. ON YOUR WRIST, MID-INTERVAL The cues your coach wrote don't get lost. When you're on the 3rd of 4 kick 50s, your watch shows you "finish last 15M hard kicking!" exactly as written. No more memorizing the sheet before you push off. FULLY ON-DEVICE The parser is a real language model running locally on your iPhone using Apple's MLX framework. Your workouts never touch a server. No account. No subscription. No internet required after the one-time model download. EXPORTS THAT WORK Send to Apple Watch via WorkoutKit, with swim-native pool intervals and your notes attached. Export as FIT, the Garmin-native format. Upload to Garmin Connect, TrainingPeaks, or any service that reads FIT. Your rep counts, rest intervals, strokes, and equipment come through cleanly. EDIT BEFORE YOU SWIM Review the parsed workout before you export. Drag to reorder. Tap to edit. Add a warm-up interval or fix a typo. Your workout, your way. BUILT BY A TRIATHLETE Designed by someone who actually trains. If a feature doesn't help you get in the water faster, it's not in here.

The call

Swim Structured's advantage is update cadence (every 3 weeks vs every 2 months). On rating, ads, in-app purchases and device support there is nothing between them.
