Estimated 1RM Trends

1RM tracker for iPhone strength training.

Compass gives iPhone lifters an estimated 1RM tracker that updates from the sets they already log. You do the workout once, then use PR chips and trend charts to see whether your strength is moving over time.

Strength Signal

Progress that is visible without max-testing every week.

Instead of relying on memory, Compass turns regular training sets into an estimated 1RM signal you can review after every session and across longer timeframes.

Estimated 1RM from logged sets

Compass derives estimated 1RM from your actual work sets, so you do not need separate max-testing sessions to see direction.

Trend charts over time

Review whether strength is moving across days and weeks instead of judging progress off a single workout.

PR chips after sessions

Workout summaries call out weight PRs, rep PRs, and estimated 1RM PRs as soon as you earn them.

Why It Matters

Why this capability gets people to keep the app installed.

A clear strength signal for people who want more than weight-on-the-bar history.
Trend review without maintaining a separate spreadsheet.
PR feedback tied to the workout you just completed.

What Compass Does

Concrete product proof, not vague fitness copy.

Exercise detail and Stats surfaces show estimated 1RM trends.
Workout summaries highlight PR, rep PR, and estimated 1RM PR events.
The signal comes from logged sets, so every normal session improves the trend history.

How To Use It

Three steps from feature interest to actual training value.

1
Log your working sets in Compass.
The tracker works from the training you already do, so you do not need extra max-testing sessions just to get a signal.
2
Review estimated 1RM in Exercise Detail or Stats.
Use the app surfaces that already summarize strength movement over time instead of exporting the raw sets elsewhere.
3
Judge the trend, not one isolated number.
PR chips and the broader history make it easier to tell whether your programming is moving strength in the right direction.

FAQ

Questions that block the install.

Is Compass showing a true tested 1RM or an estimate?

It is an estimated 1RM derived from your logged sets, which is useful for tracking direction without needing a true max single every week.

Do I need to test a max single for the tracker to work?

No. Regular training sets are enough for Compass to calculate estimated 1RM and show the trend.

Can I see new PRs right after a workout?

Yes. Finished-workout summaries call out PR, rep PR, and estimated 1RM PR results from the session you just logged.
