Rune home screen: today’s scheduled Pull workout and an 18-week consistency grid

Today

Open it and know.

The day’s scheduled workout, your program at a glance, and an 18-week consistency grid — a calm record of showing up, not a streak to protect.

Logging

Beat last session, set by set.

Every set shows what you lifted last time, so the next mark is always in view. Tap the check and move on — with a plate calculator and rest timer when you want them. A dead battery won’t lose your session.
