More Free Apps for iPhone and Apple Watch
Tidal Breath is one of a family of five small, private apps from the same maker, and every one of them is free.
Heat and Cold, Within Clear Limits
A sauna and cold water coach that keeps your eye on the time. It sets cautious limits while you are new, warns you as you near them, and walks you through warming back up afterwards.
On iPhone
- Guided mode, with cautious limits that build up slowly
- Sauna, steam, contrast and cold sessions
- Your time in the heat and the cold, week by week
- Spotter, so someone knows when you are in
On Apple Watch
- A ring counts down, with a warning and an alarm at your time
- Tap I’m Out when you are out
- Heart rate on your wrist, and live water temperature on a Watch with a water sensor
- Rewarm guidance once you are out of the water
Heat and cold are risky for some people. Read the safety page first.
Mobility Your Watch Talks You Through
Short guided routines for stiff hips, tired legs and long days at a desk. A calm voice names each move and counts you in, and your Watch taps at every change, so you never need to look at a screen.
On iPhone
- 36 routines of 5, 10 or 15 minutes, browsed by body area
- 66 moves, each with a written guide, an easier and a harder option
- Make any routine your own, or build one from scratch
- History with heart rate, and a forgiving streak
On Apple Watch
- Runs start to finish with no iPhone nearby
- A ring for every hold, with strong taps over the last five seconds
- Voice through AirPods or the Watch speaker
- Turn the Crown to set the voice volume
Let the Day Ebb Away
Wind down, sleep, wake gently. Tidal Sleep adds to the Apple Watch, Oura, Garmin, Withings or WHOOP you already own: it takes the stats they record and extends them with the hour before bed, the 3am wake-up and your dreams. No wearable? It works on its own.
On iPhone
- Six guided wind-downs in six voices, each labelled by how strong the evidence is
- Sea sounds generated live on your phone, on a timer
- A clock-free night mode with a simple path back to sleep
- A voice dream journal, transcribed on your phone, and an optional lucid dreaming course
- Your night as a tide chart that leads with regularity, not a score
On Apple Watch
- Slow breathing paced by gentle taps on your wrist
- A haptic alarm in a wake window, so your partner sleeps on
- Sleep stages and heart rate through Apple Health
Every claim on the site is sourced and graded, and every number is marked as an estimate.

Say It Twenty Times, the Way Coué Taught
Émile Coué asked people to say one line twenty times, morning and night, counting on a knotted string. Twenty Knots brings that method to your iPhone, your wrist and your car, so the count is the same wherever you pick it up.
On iPhone
- Record your own affirmations, in your own voice
- Coué’s formula and nine more, in British, American and Australian voices
- A short daily reading from Coué’s own writing, sixty-four in all
- A quiet calendar, with no streaks and no scolding
On Apple Watch
- Playlists stored on the Watch, so your iPhone can stay at home
- Listen through AirPods, or follow in silence with a tap for every knot
In CarPlay
- Your playlists on the car’s display, ready for the commute
- Start, pause and skip from the screen, the wheel or Siri
