Drop an osu! replay (.osr) for a full breakdown — every stat in the file, your cursor & key analysis, and Unstable Rate / hit-error. It's parsed right here in your browser session — nothing is stored.
Drop your .osr here
or click to browse — replays live in osu!/Data/r/ or your Replays folder.
osu!standard replays give the richest breakdown. Other modes parse, but timing analysis is std-only.
Unstable Rate is the standard deviation of your hit-timing errors multiplied by 10. A lower UR means more consistent tapping — you hit notes at the same offset every time. Strong players sit around 60–110 UR on demanding maps.
An .osr is osu!'s replay file. Local replays live in your osu! install under Data/r/, and you can export any play from your profile. Drop the .osr here to analyze it.
No. The replay is parsed in your browser session purely to produce the breakdown — it is never saved on our servers and you do not need an account.
Hit error is how far each tap landed from the perfect time, in milliseconds. Negative is early, positive is late. A consistent early or late bias means your timing is offset and worth correcting.
It maps where your cursor spent time across the playfield during the play — brighter cells are where you aimed the most.
