Heala vs WHOOP

Let us be straight about this one: WHOOP is a strap with sensors on it and Heala is an app. We do not replace the hardware, and any page telling you otherwise is selling something.

WHOOP measures

• Continuous heart rate
• Overnight HRV
• Respiratory rate
• Skin temperature
• Sleep staging

Heala decides

• What to train today
• What to eat against it
• Body composition over time
• And reads the strap

What WHOOP does that no app can

It measures. Continuous heart rate, heart-rate variability overnight, respiratory rate, skin temperature, sleep staging from actual sensor data — a phone in your pocket cannot produce any of that.

If your question is "how recovered am I, physiologically", dedicated hardware is a better answer than any software estimate, and that includes ours.

What the strap does not do

It does not know what you ate. Nutrition is the single largest lever on body composition and it is not something a wrist sensor can see.

It does not write your training. It reports strain and recovery; deciding what Thursday should look like is left to you.

And it is a subscription with hardware attached — the membership continues whether or not you wear it.

The actual relationship

Heala reads WHOOP. Anything the strap writes to Apple Health or Health Connect — sleep, heart rate, workouts — arrives in Heala and sharpens its recovery score, and the app then does the parts the strap cannot: food, programme, body composition, the plan.

If you own a WHOOP, keep it. If you are deciding whether to buy one in order to get recovery data, know that Heala produces a usable recovery signal from your phone alone, and a wearable makes it better rather than possible.

Native capability. WHOOP requires its own hardware and membership.
