The privacy policy and update check now use the new site address, markarov.dev. The old address keeps working for now, but it will be retired. Nothing else changed.
Names its own timing error in milliseconds, measured on your phone. No network.
A click at a tempo you set. It is not a studio metronome and not a clip-on. Every metronome in this category calls itself precise. None of them says how precise, on which phone, or over how many bars. This one does: it measures the distance between the beat it promised and the beat it played, adds it up over a hundred bars, and prints the result in milliseconds on the «about» screen — with the number of bars and the name of your phone next to it. Measured on a Samsung Galaxy S21: 1.1 ms per beat over 124 bars. Set the tempo, pick a time signature and press start. The click stays on the phone; nothing is uploaded. • Its own deviation, measured on your phone and printed in milliseconds • Tempo from 20 to 300 bpm, one beat at a time, or tapped in • Time signatures 2/4, 3/4, 4/4 and 6/8 — and a page explaining what they mean, plus 5/4 and 12/8 • Subdivisions of the beat, each with its own quieter click • A steadiness trainer: every second bar goes silent • Works in airplane mode: the beat is counted on the device • The whole installer is 44 KB — the nearest comparable open metronome is 3 MB • English, Russian and Polish Wireless headphones deliver the click later than the speaker. By how much, this app does not measure — so it names the fact and not a number. For a performance use the speaker or a wired output. No ads. No account. No network permission at all: the app has no way to send anything anywhere, which is also why it works with the phone in airplane mode. Independent development: one person builds and maintains this app. A letter to support@markarov.dev is read by that person, not by a support desk.
