Swim1K
Do you love the idea of swimming but always run out of breath after a few lengths? Swim1K takes you from that breathless, scrambling feeling to a smooth, confident 1km.
Launching this summer on iPhone and Apple Watch. Join the waitlist and we'll let you know the moment it's ready.
The only app dedicated to taking you from beginner to swimming 1km non-stop. Swim1K guides you through a plan built around how you feel, not how fast you go, one calm length at a time.
A plan that constantly adapts to your progress and adjusts your swims to meet your needs. No streaks to protect, no targets flashing red, just swimming at your pace.
When you reach the pool, your watch already knows your next session. Pick hard, medium, or easy depending on how you're feeling, and start your guided swim
More lengths alone rarely breaks the plateau, efficiency will. Swim1K teaches you how to find your natural rhythm so every length takes less effort.
It's not a random number. A 1km swim takes about 30 minutes, the same as a Couch to 5K run, and the zone linked to lower blood pressure, better sleep, and a lighter mood.

Getting there is more about rhythm than fitness. Small wins, every session, until one day you just keep going.
Water is 800x denser than air, which means every length is a full-body resistance workout. You get a stronger, leaner and fitter body without the strain of the gym or running.
Fitter
30 mins of swimming can put you in the same cardiovascular zone as a steady 5K run, without the miles on your body.
Taller
Swimming builds the back and core muscles that hold you upright. Most people notice better posture within weeks, without a single stretch class.
Effortless
Low impact, high reward. A proper workout that won't leave you hurting the next day. The swimmer's body, without aches and injuries.

Most swim apps are built to make you faster. Swim1K is built around how you feel. Swimming is known to bring less stress, better sleep, and a clearer mind that you'll carry out of the pool and into your day.
Breathing, rhythmic movement and immersion measurably lower the stress hormone cortisol, every time you swim.
The release of endorphins and serotonin stays with you for hours, helping to improve your energy and mood.
All these benefits contribute to deeper, better quality sleep. You'll wake up clearer and more rested day after day.
Swim1K comes from the maker of Pennies, the everyday budgeting app with over two million downloads, thousands of 5-star reviews and multiple Apple Editors' Choice awards. We're putting the same care into the pool.
