## What is Parry Lab?

An enemy winds up. The blade lands. You press. Miss by 40 milliseconds and this app tells you it was 40, not just that you failed.

Parry Lab is a measurement tool for action game players who want their deflect timing counted instead of guessed. Every input is judged and printed with a signed millisecond figure, so you always know whether you went early or late and by exactly how much.

[HOW IT WORKS]
- An enemy silhouette winds up an attack
- Press the instant the blade lands to deflect it
- A feint freezes mid-swing and then resumes, so wait for the real impact
- Red attacks cannot be deflected at all, so keep your hands off them
- Pressing with nothing landing counts against you, so mashing is punished

[WHAT YOU GET]
- A signed millisecond figure on every single attack, not a vague grade
- Session report with a distribution chart and a plain diagnosis such as "you press 27ms late on average"
- One-time calibration measures your device screen and touch delay, so the figures are real and not estimates
- 15 hand-authored movesets, ramping from steady wind-ups to feints, undeflectable attacks and shifting tempo
- Anonymous global boards sorted by the lowest average deviation, a metric that mashing cannot fake
- Best average deviation and longest streak saved for every moveset
- Clean, distraction-free design built around one clear contact point
- Plays in 9 languages
- New movesets arrive without waiting for an app update

[WHY MEASURE IT]
Most players know they keep dying to the same attack, but not why. A number tells you: go 30ms sooner and the same attempt lands. A session takes a couple of minutes, so it fits right before you open a boss fight, and your average deviation keeps falling as long as you keep the routine honest.

Find out how late you really are.

## Version history (last 3 releases)

### 1.0.2 — 2026-09-11

Rankings and personal bests now use a stricter figure: every attack counts, so a run with misses can no longer outrank a complete, honest run.
A press outside the block window now reports how far off it was and appears in the distribution chart.
Movesets that introduce unblockable or feint attacks explain them before the first attack.
A run is discarded if the app goes to the background mid-session.
Fixes: the attack counter, the next-moveset button after a failed run, and calibration state after a redo.

### 1.0.1 — 2026-08-31

The app is now called Parry Lab, and its listing describes only what it does: measure your deflect timing and report it as a signed millisecond figure. No gameplay changes.

### 1.0.0 — 2026-08-25

No release notes.
