console chromatic guitar tuner.
About this app
console chromatic guitar tuner helps getting musical instruments in tune. It is ad-free, straightforward and intuitive. Only a few MB of storage are needed. The reference frequency A4 can be chosen from 432 to 443 Hz. Audio driver, algorithm and some other things can be adjusted to your instrument in the settings. The deviation from the next correct pitch is show as flowing histogram and in the color of the pitch name. Additionally the octave can be shown. While the audio engine can be freely configured, some settings might cause your mobile to choke. If you get no readings, choose smaller buffersize and samplerate values.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be de.fff.ccgt is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.51 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall ccgt first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of ccgt, and a listing is removed when the evidence for it stops holding up.
Get ccgt
Every source we list for de.fff.ccgt is legality-reviewed. Pirated or cracked builds are never offered.
