The plan answers to recovery.
When two of four fatigue signs are down, today turns into a deload: half the sets, 10% off the weight.

Questions
When can I get it?
On Android, from Google Play. Anywhere else, as a web app at app.steelheft.com that installs to the home screen. The iPhone app is coming to the App Store: take a spot in early access and we’ll write the day it’s live.
Kilograms or pounds?
Either, set in your profile. The plates follow: a 20 kg bar with 25 to 1.25 kg plates, or a 45 lb bar with 45 to 2.5 lb plates.
What stays free?
The plan, the set log, weight and measurements, and the last four weeks of history. Logging a workout is never locked.

Which languages does it speak?
English, Russian and Chinese.

It lives in your account and syncs between your devices. You can delete the account, with everything in it, right from the app.
