Swimio
Swimio · Leaning
Swimio is an AI swim training app for iPhone and Apple Watch that builds a workout from your recent training and then guides it lap by lap on the watch. It solves a specific, annoying problem: staring at a whiteboard or a notes app and never being sure what to swim. You can also snap a photo of your coach's whiteboard and let Smart Import turn it into a structured swim set. It syncs with Apple Health and supports Strava, so your pool sessions land in the same place as the rest of your training. Free to start, and built for individual swimmers, coaches, and teams. Think of it as a swim workout planner that actually thinks. No more guessing at the pool deck.
About Swimio
What Is Swimio
Swimio is a swim coaching app that runs on iPhone and Apple Watch. Instead of handing you a static library of sets and hoping you pick well, it looks at what you've been swimming lately and generates a session that fits, then walks you through it on your wrist. The pitch is simple: you never have to wonder what to swim again. That matters more than it sounds.
The whiteboard problem is the real hook here. Coaches still write sets on a board, and swimmers still photograph it and retype it later. Smart Import reads that photo and turns it into a structured workout you can actually follow, which matters most for anyone training under a coach or a club plan. Individual swimmers get the same benefit from AI-generated sessions built around their own history.
So who is this for? Mostly pool swimmers who already wear an Apple Watch and want someone else to handle the planning.
The honest limit: Swimio lives entirely in Apple's world. There's no Android version, no Garmin or Wear OS support, and the coaching guidance depends on an Apple Watch on your wrist while you swim. If you train with a non-Apple watch, this app isn't for you. Simple as that.
Getting Started
- Download Swimio from the App Store and pair your Apple Watch, then grant Health access so the app can read your recent swims.
- Set your pool length, typical distances, and goals so the AI has something to build around.
- Generate a session, or take a photo of a coach's whiteboard and let Smart Import convert it into a structured workout.
- Head to the pool with your watch and follow the lap-by-lap guidance, with sets, rest, and pace shown as you go.
- Review the session on your iPhone afterward, and let it sync to Apple Health and Strava alongside your other workouts.

Key features
AI workout generation
Swimio builds a session from your recent training rather than pulling a random set from a list. The idea is that the workout reflects where you actually are right now, not where a generic plan assumes you should be. It's the feature that carries the entire "never wonder what to swim" promise.
Smart Import for whiteboard photos
Point your camera at a coach's whiteboard and Swimio reads it into structured swim workouts you can follow on the watch. For anyone training under a coach, this removes the tedious retyping step that eats into pool time. It's the most distinctive thing in the app. No whiteboard, no retyping. Just swim.
Real-time Apple Watch guidance
During a swim, the watch walks you through the session lap by lap, showing the current set, rest, and pace target. You keep your eyes off the phone and on the water. Guidance runs on Apple Watch, so it works without hauling the iPhone to the pool deck.
HealthKit sync
Every completed swim lands in Apple Health, which means your training history lives alongside workouts from other apps. That's the foundation for the AI suggestions, and it gives you a clean record to look back on. It's also what makes Swimio work as a swim tracking app, not just a workout generator.
Strava integration
Swims sync to Strava, so pool sessions sit next to your rides and runs in a single feed. If Strava is where your training friends see your work, this keeps you from logging it twice. Set it once. Forget it after that.
Built for coaches and teams
Swimio is pitched at coaches and teams as well as individuals. The whiteboard import and structured set delivery make it useful for bringing a group's written plan into a format swimmers can follow on their own watches.
Pros and cons
Pros
- The AI builds sessions from your own recent training, so workouts stay relevant to your current fitness.
- Smart Import turns whiteboard photos into structured workouts, which saves real time for coached swimmers.
- Lap-by-lap Apple Watch guidance means you don't have to memorize sets or check a phone mid-swim.
- HealthKit and Strava sync keep your swim history in the same places as the rest of your training.
- Free to start, so you can test the coaching flow before paying.
Cons
- iPhone and Apple Watch only. Android users and anyone on Garmin or Wear OS can't use it at all.
