## What is Diastra · Heart Rate Training?

Plan apps tell you what to do. Tracker apps tell you what you did. Neither tells you if it worked. Diastra does both jobs, and it connects them.

Job one. The plan. Built from your real weeks, not a template. Mostly easy, a little hard, the mix the science backs. It climbs when you grow and eases when you are run down. Miss a week? The plan rebuilds around what really happened.

Job two. The measure. Every workout is read minute by minute against your own normal. Your effort is sorted into what it really was. Easy. Threshold. VO₂max. A hard minute only counts when the effort truly held. Counted, not guessed. It starts on day one, reading every workout your watch ever saved.

The plan sets the work. You work the plan. Diastra grades what happened. The next week gets smarter.

Week after week, you see which way you are moving. Getting fitter. Holding steady. Slipping.

Workouts end. Fitness stays. Diastra measures.

On Apple Watch

Record from your wrist. Live heart rate, and a gentle tap when you drift out of your band. Finished workouts save to Apple Health.

Diastra works without an account.
