Swimio
Swimio plans swim workouts on iPhone and guides them lap by lap on Apple Watch. The visual builder, AI Coach, and Smart Import turn goals, coach texts, or whiteboard photos into structured sets with warm-ups, main sets, and cool-downs, then sync send-offs, pace, and heart-rate zones to your wrist during the session.
Most swim apps either log laps after the fact or dump a static PDF on your phone. Swimio closes the loop from planning to in-water guidance to post-swim analysis, and Pro adds training-aware recommendations that read your last 28 days of load before suggesting today's distance and intensity.
Pool swimmers, triathletes, and coaches use Swimio when they want one shared plan across lanes. Basic stays free with three saved workouts, while Pro unlocks AI generation, photo import, unlimited libraries, and roster tools for assigning sessions to squads.

How much does Swimio Pro cost?
Swimio Pro is $6.99 per month or $44.99 per year through the App Store, which Swimio lists as $3.75 per month on annual billing. Subscriptions are managed securely inside Apple's subscription settings.
How does Swimio Smart Import work?
Swimio Smart Import accepts pasted coach messages or photos of pool-deck whiteboards, then detects sections, distances, strokes, repetitions, and intervals. You review the structured workout in Swimio before saving or sending it to Apple Watch.
Does Swimio connect to Strava?
Swimio can upload completed swims you recorded inside the app to Strava when you grant permission. Swimio does not import or analyze existing Strava activities, keeping the training history it coaches from inside its own logs.
Can coaches assign workouts with Swimio?
Swimio Pro includes roster and team assignment tools so coaches can send structured sessions to swimmers or squads and see who completed the workout. Swimio also offers team plans for pools that need shared schedules and results boards.
