About

Who builds Arry
and how we write the site

Arry shows recovery, training load, sleep, and HRV using Apple Health data. This page explains the product and how we source health-related statements.

Who is behind Arry

Arry is developed by Dmitry Rusakov. When describing the app, we explain which data is used and how it can inform daily load choices, without presenting Arry as a medical tool.

How site materials are prepared

  • feature pages describe what people can actually see and do in the app;
  • health articles list the books, reviews, and peer-reviewed publications they rely on;
  • feature descriptions are kept separate from broader health claims.

Editorial principles

  • no promises of “perfect readiness” or error-free predictions;
  • no suggestion that an app can replace medical advice;
  • clear descriptions of the data used and what a result represents;
  • sources listed for health-related claims.

Where to check the details

Information about Arry is split across three types of pages:

  • methodology explains which measurements go into the recovery score;
  • privacy explains which data is used and where it is stored;
  • feature pages show how those choices appear in day-to-day use.
