Overview
Most APM tests give you one number and stop. This one measures the reaction time of every single key separately — so you learn not only how fast you are, but which key is slowing you down.
The metric itself comes from real-time strategy games: StarCraft players were the first to be judged by their APM, and it is still the most quoted speed figure among RTS and MOBA players. While you play, the tool records the time between "target key appears" and "you hit it correctly", keeps that figure per key, and shows it next to a live keyboard heatmap and an effective-action rate (correct hits ÷ total actions — the EAPM idea). Every run is then accumulated per scheme, so each profile has its own history.
Schemes cover FPS, RTS, CS2, Fortnite, Overwatch and a fully custom key set, with keyboard and both mouse buttons counted together; run lengths are 5, 10, 30 or 60 seconds. Scores, custom keys and history stay in your own browser. One disambiguation note: this is the APM of gaming, not the APM of IT monitoring, and not Raven's Progressive Matrices.
How to Use
- Select scheme (FPS/RTS) and duration.
- Click start, wait for 3-2-1-GO countdown.
- Press the highlighted key quickly and accurately.
- View APM, accuracy, and heatmap after test ends.
Feature Details
What is per-key latency? It is the time from the moment a key is asked for to the moment you press it correctly — measured separately for every key. It is the part of APM that a single total hides: two players can both average 250 APM while one of them loses 40 ms every time the prompt lands on a mouse button or a pinky key. Here that number is a first-class result, tracked per key across runs.
APM vs EAPM. Raw APM counts everything, including mashing that changes nothing in the game. The StarCraft community introduced EAPM (Effective APM) to count only actions that actually do something. This test reports both sides: every keypress and mouse click in the scheme raises your total actions, while only presses that hit the highlighted target raise your correct actions — and the accuracy figure is exactly your effective rate for that run. 300 APM at 60% accuracy is usually a worse sign than 200 APM at 95%: the first player is guessing, the second is reading the screen.
What you get after a run — four things worth reading
- Per-key latency. The average time between "target key appears" and "you hit it correctly", for each key. The slowest key is marked in red. Most players are not uniformly slow — they lose time on two or three specific keys, and this line exists to find them. Keys with fewer than 3 samples show their sample count (for example
W 120ms (1)) so a lucky press is not read as a result. - Keyboard heatmap. Five heat levels show where your input actually goes. If heat concentrates on a couple of keys, you are substituting comfortable keys for the ones the scheme asks for — in a match, that means commands that never get issued.
- Effective action rate. Your ratio of fast to useful for that run, as above.
- History, per scheme. Every run is stored locally (never uploaded) and accumulated separately per scheme — best, average, lowest, accuracy, totals — and the key-latency line is per scheme too, so FPS and RTS numbers never contaminate each other.
How to train with it
- Start with the red key — that is your current bottleneck. One focused run beats blindly raising total speed.
- Then watch accuracy: if APM rises while accuracy drops, you are rushing. Bring accuracy back above 95% before pushing speed again.
- Use 5 / 10 seconds for reaction and precision, 30 / 60 seconds for stamina and consistency. The gap between the two run lengths is a signal in itself.
- Mouse buttons are tracked as their own keys — for many players the slowest "key" turns out to be one of them.
Two notes on clean data. The first hit of a run is excluded (that is your reaction to the start), and any interval longer than 3 seconds is excluded (that is attention drift, not reaction). Because the result card is space-limited it prints only the slowest keys; the full per-key data lives in the on-page key-latency line and the history panel.
Benchmarks
Ranges below are the ones most often quoted by the StarCraft and RTS community, not measurements taken by this site — treat them as a rough yardstick. This test measures your raw input speed in the browser; in-game APM is counted by the game itself. And remember: effective actions (EAPM) matter more than the raw count — precise input beats mashing.
| APM Range | Typical Player | What It Means |
|---|---|---|
| 60–120 | Casual / non-competitive player | Comfortable speed for single-player RTS and most MOBA play |
| 120–200 | Regular RTS / MOBA player | Enough to keep up with ranked matches without feeling rushed |
| 200–300 | Competitive RTS ladder | Fast, deliberate play — combos and camera control stay accurate |
| 300–400+ | Professional StarCraft players | The range most often quoted for pro-level StarCraft II matches |
| 400–600 | Extreme bursts / showcase runs | Short bursts at the top end; rarely sustained for a whole match |

FAQ
What is per-key latency, and why does it matter more than a total?
Per-key latency is the time between "this key is asked for" and "you press it correctly", measured for each key separately. A total APM figure hides it: you can have a great average while losing tens of milliseconds every time a specific key comes up. This site tracks it per key and marks the slowest one in red, which is what you actually need in order to improve.
How is the per-key latency measured?
The tool prompts a target key and records the elapsed time until you hit it correctly, averaged separately for each key. The first hit of a run is excluded (it is your reaction to the start), as is anything slower than 3 seconds (that is attention drift, not reaction). Keys with fewer than 3 samples are marked with their sample count so you do not mistake a single lucky press for a result.
How is this different from other online APM tests?
Most APM tests output a single number and stop there. This one takes every run apart: per-key latency, a keyboard heatmap and an effective-action rate, accumulated separately per scheme — so you learn where your speed breaks down, not just how big the number is.
How do I find my slowest key?
Run any scheme for 30–60 seconds, then read the key-latency line under the keyboard: it lists each key with its average time and marks the slowest one in red. Mouse buttons get their own entry. If a key shows fewer than 3 samples, give it another run first — thin samples are not a verdict.
Why is my score low when I feel like I am pressing very fast?
Accuracy is usually the bottleneck: only presses that hit the highlighted target count as correct. Check the effective rate (correct ÷ total) on the scoreboard, and the slowest keys marked in red in the key-latency line — a fast blind run loses more time to corrections than it gains from speed.
What counts as a good APM?
Casual players sit around 60–120; regular RTS and MOBA players are mostly in the 120–200 band; competitive ladder play reaches 200–300, and professional StarCraft players are commonly quoted at 300–400+ in intense matches. Run a test and see where you land — and remember that effective actions (EAPM) matter more than the raw count.
What is the difference between APM and EAPM?
APM (actions per minute) counts every keystroke and click, including wasted input. EAPM (effective APM) counts only the actions that actually change something in the game. This test reports both faces: total actions and correct actions, so the accuracy figure is your effective rate for that run.
Can I measure keyboard and mouse latency in the same run?
Yes. Keyboard input is always recorded, and the FPS, RTS, CS2, Fortnite and Overwatch schemes also include the left and right mouse buttons — both hands count, and mouse buttons get their own per-key latency entry. For many players that entry is the slowest one on the board.
Why do StarCraft and RTS players track APM?
Real-time strategy games are where the APM benchmark comes from: you manage economy, production and camera control at the same time, so a higher APM means more chances to get all of it done. The RTS scheme here reproduces that "keyboard plus both mouse buttons" load, and the benchmark table gives you a range to compare against.
How is APM different from CPS?
CPS (clicks per second) measures raw clicking speed on a single target — a fine metric for click-heavy games, but it ignores the keyboard entirely. APM covers the whole input set: keys, movement, hotkeys and mouse buttons. We also have a dedicated CPS test if you only want click speed.
Is my data uploaded anywhere?
No. Scores, custom key sets and history live in your own browser (localStorage) and are never sent to the site. The clear-history button in the panel removes them whenever you want.
