An AI advisor, not just a graph
The app listens to individual drums and advises which way to tune. The user gets guidance, not raw numbers.

TUNERO — a drum tuner with AI
An app that listens to your drum and tells you what to do about it. Not a graph you have to interpret — a concrete instruction on which lug to turn.

The brief
Tuning drums is a skill that takes years to learn. Existing tuners show you a frequency and leave you guessing what to do with it. For a beginner that is about as useful as a thermometer with no advice attached.
We wanted an app that takes the last step for the user: it listens, it understands, and it says what to do next.
What we built
Kits, songs, presets
Every kit keeps its own settings; songs get the tuning that belongs to them.
Sync across devices
Your kits survive a reinstall and a move from iOS to Android. A standard export file is always available — even without an account.
AI that cannot run at a loss
The AI runs on credits the user buys, metered server-side. One heavy user can never eat the business.
Its own website
The app comes with tunero.app — dark design, an animated hero and instant loading.

The result
A tuner that does not stop at the measurement but at the advice — which is exactly what sets it apart from the tools it competes with.
Audio and AI run in native code and on the server, not in a browser wrapped in an app. The latency is where it belongs: unnoticeable.
