HIIT & Tabata Timer for Watch

Circuit Training Fat Burn

Interval training falls apart the moment you have to look at a phone to find out whether you are working or resting.

What it does

• Custom work, rest, warm-up and cool-down intervals with a round count
• Haptic and audio cues on every transition, so you never look at the screen
• Live heart rate and calories during the session
• Fully standalone on the watch - no phone in the gym

Do I need my iPhone?

Not while you are using it. This is a standalone watchOS app: it runs on the Apple Watch on its own, with the phone switched off or left behind. You do need an iPhone once, to purchase and install it — that is an App Store rule rather than anything about this app.

Questions

What is the difference between HIIT and Tabata?

Tabata is one specific HIIT protocol: eight rounds of 20 seconds work and 10 seconds rest. HIIT is the general category, and this app times both.

Do I need my iPhone with me?

No. Start, train and finish on the watch alone.

Does it record heart rate?

It shows live heart rate and calories during the session.

Can I save my own interval presets?

You can configure work, rest, warm-up, cool-down and rounds to match the session you actually do.

I build apps like this for clients too — see what that involves.
