Ice bath app with timer and Strava sync

Key takeaways

• Degree Daddy tracks ice baths, cold plunges, and sauna sessions in one app.
• Timer runs from iPhone or Apple Watch, and survives backgrounding.
• Log water temperature in °F or °C for every session.
• Pushes to Strava, which has no ice bath activity type of its own.
• Writes to Apple Health for Whoop, Oura, and Garmin.
• Free during beta, no account, works offline.

An ice bath is two to five minutes long, which makes it the single hardest kind of session to log consistently — the record-keeping takes as long as the activity. An app that removes that friction is the difference between having a training history and having a vague memory.

The timer

One tap to start. Large, readable countdown. The session persists if the app is backgrounded or the phone locks. The Apple Watch app is the practical way to run an ice bath, since you can start and stop from your wrist without touching a phone with wet hands.

Temperature and history

Log the water temperature every time, in °F or °C. Over weeks this becomes the only objective record of your cold tolerance — the difference between three minutes at 50°F and three minutes at 38°F is substantial, and it is invisible if you only record duration.

Full session history keeps duration, temperature, venue, and a one-to-five rating for how it actually felt.

Streaks

Current streak and personal best, with grace days so a missed day does not erase months of work. For most people this is the mechanism that keeps the habit alive.

Strava

Strava has no ice bath activity type. Degree Daddy creates the activity for you as a Workout, with your duration and temperature in the name, and deep links to the new activity so you can attach the session card as the photo. Details at how to add an ice bath to Strava.

Apple Health

Sessions write to Apple Health as workouts with temperature data. Whoop, Oura, Garmin, and anything else that reads HealthKit picks them up with no additional setup, so your cold exposure sits alongside the rest of your recovery data.

Cost and privacy

Free during beta with no subscriptions, ads, or in-app purchases. No account required — sessions are stored on your device and sync across your own devices through iCloud.

Frequently asked questions

Is there an ice bath app for iPhone?

Yes. Degree Daddy is an ice bath, cold plunge, and sauna app for iPhone, iPad, and Apple Watch with a timer, temperature logging, streak tracking, Strava integration, and Apple Health sync. It is free during beta.

Can I post an ice bath to Strava?

Yes. Strava has no ice bath activity type, so Degree Daddy creates the session as a Workout activity with your duration and water temperature in the name, pushed with one tap after you connect Strava once.

Does the ice bath timer work on Apple Watch?

Yes. Degree Daddy includes a standalone Apple Watch app, which is the practical way to run an ice bath — you start and stop from your wrist instead of handling a phone with wet hands.

Does the app track water temperature?

Yes. Log the water temperature for every session in °F or °C. The history lets you see your cold tolerance progress over time, which duration alone does not show.
