Train the week, not the day.
Most logs forget you between sessions. Temper walks in Wednesday knowing exactly what Monday cost — rotating your patterns, recording your real rest, and sizing the day to the energy you brought.

Day 2
It remembers the week your body already paid for.
Triple Strength — three ideas doing the heavy lifting. Each one closes a gap ordinary logs leave open.
Week-Aware Rotation
Push, pull, overhead, hinge — Temper rotates the patterns across your week so Monday's lead lift never ambushes you Wednesday. Smart default picked, every option still yours. Stop spinning your wheels.

One tap starts the clock; it bends ±15s mid-breath, runs past zero when you do, and writes the rest you actually took into every set. Miss your reps? Temper suggests the extra rest that buys the next set back.

Slept four hours? Tap Drained — the heavy work stays, the fluff goes, and you leave stronger instead of buried. The bar doesn't care how you feel. Open it.
Primed · Normal · DrainedOpen it. Lift. It remembers the rest.
The whole flow is built to keep your eyes off the screen and on the bar.
Pick the Lift
Temper shows the smart default for today plus the alternates. Tap one and the choices collapse — just your working sets remain.
Log & Rest
Enter weight and reps. Tap rest — it starts instantly at your preset, pings once at zero, then quietly counts up until you're back.
Finish & Recall
End the session and it rolls the rotation forward. Next time, each lift shows last week's sets, real rest, and your note — a nerve you tweaked, a cue that worked.

Nothing staged — these are captures of the current build running a three-year log: 307 sessions, 5,500+ sets.

The Forge Is Still Hot.
Temper is being tempered — one lifter, real iron, a growing pile of revision notes. No sideloads, no waitlists, no "drop your email." The day it stops flinching under a real workout, the button below goes live and you get the finished thing.
Until then: the docs show exactly how it thinks, and the roadmap shows where it's going.
