Know if your training is working.

Plan the block. Train it. Understand what moved, and trust the data underneath. Every set feeds the next.

01PlanWeb

Program the block you actually mean.

Set types from warm-up to failure. Exact reps, ranges, or AMRAP. Effort as reps in reserve, tempo, rest, even loads written as a percentage of your top set.

Logging that keeps up.

What you did last time, what to load this time, and a rest timer that follows you to the lock screen.

Your last session, right there
Last time's weight, reps, and effort sit under the set you're logging. Autofill them and move on.
A suggested load
Worked out from your logged sets and estimated 1RM, adjusted for the reps you left in reserve.
Built for mid-session
The rest timer runs in the Dynamic Island, the workout minimizes while you reply, and whole sessions log offline.
Cardio gets the full treatment
Live pace, GPS routes, moving time, kilometre splits, and intervals executed against their targets.

Every finish gets a proper celebration: PRs called out with their own haptic, and sharing that trims the start and end off your route before it goes anywhere.

Am I progressing, and why?

The progression diagnosis reads your history and gives a straight verdict: progressing, stalled, or declining. Then it shows the drivers.

Kiron history overview on the web: top sets per lift with trend sparklines, three months of workout, set, and PR counts, a list of new bests, and training focus split by muscle group.
Fig. 03-AProgression diagnosis
A clear verdict*
Each lift gets a call based on where your estimated 1RM is actually heading. If there isn't enough data to say, it says that.
Four drivers*
Frequency, effort, load versus reps, and how recent your last PR is. Each one shows which way it's pulling.
Effort counts in the math
Estimated 1RM credits the reps you left in reserve. Warm-ups and drop sets never set a PR.
Cardio gets a read too*
Your fastest 1 km, 5 km, and 10 km pulled straight from your routes, plus pace and heart-rate trends across the block.

A diagnosis is only as good as the data.

One mistyped set shouldn't skew the trends and PRs everything else depends on. Kiron is built so it can't.

Correct the record
Fix a mistyped set after the workout closes, or repair a previous-performance entry from your history.
Suggestions stay honest
Every suggested load records whether you accepted, edited, or rejected it.
Plays nicely with Apple Health
Continuous import, twelve months of backfill, and write-back to Health.
It leaves cleanly*
Export your history to CSV and PDF whenever you want. Delete your account and the data goes with it.
