What Is Poseidon Ascending?

The world's first hyper-personalized swim-interval coach. It runs on your WearOS or WatchOS smartwatch and tells you when to relax and when to explode.

Why It Works

No More Monotony

Unpredictable sprint intervals keep your brain engaged. You never know when the next push is coming, so boredom never gets a chance.

Massive Conditioning Gains

Short, unpredictable bursts create a powerful HIIT effect in the pool. Build speed, power, and endurance without overthinking.

Hands-Free Coaching

The vibrations guide you effortlessly. Feel when to start, sprint, and recover — eyes on the water, not the watch.

Adaptive AI (Coming Soon)

With a Polar H10 chest strap, Poseidon will adjust sprint intensity and recovery based on your heart rate in real time.

Mythic Immersion

You're not just swimming laps. You're learning to unleash explosive power at the right moment, like the god of the sea himself.

How It Works in the Water

  1. Start the session. Your watch gives a clear "calm start" vibration pattern.
  2. Swim easy. Move through a randomized calm phase.
  3. Get the sprint command. A distinct sprint pattern hits — you explode into freestyle.
  4. End of sprint. A triple finishing signal tells you the effort is complete.
  5. Repeat the ritual. Calm, surprise, effort, recovery — until you're done.

FAQ

When is it going to be available?

We're aiming for a Q1 2026 launch. If you are on WearOS and want to try it out earlier for free, leave the email below and we'll get you in the loop.

What equipment do I need?

A WearOS smartwatch at launch, with WatchOS support to follow. A Polar H10 heart-rate strap is optional but recommended for advanced features.

I don't have a smartwatch. What smartwatch should I buy?

Samsung Galaxy Ultra seems to be a good option. However, any WearOS smartwatch that can go underwater and with good haptics should be fine.

Is this safe for beginners?

Yes. Poseidon can start with gentle sprint intervals and long calm phases. You control the intensity.

Why random sprints?

Predictable workouts make the brain bored and lazy. Unpredictable intervals keep you alert and improving.

Why "Poseidon Ascending"?

Poseidon Ascending enables you to ascend from comfort into challenge, from challenge into mastery.
