What Your Support Makes Possible
100% Free & Fast for Everyone
We believe fundamental music utilities should never be trapped behind paywalls, intrusive 30-second video ads, or subscription barriers.
Algorithmic Pitch Accuracy
Support helps us refine sub-cent pitch detection algorithms and frequency harmonics so your strings register instantly even in noisy rooms.
New Tunings & Tools
From Slack-Key to Guitalele, Sopranino to Bass Ukulele, supporter donations fund synthesis of high-fidelity reference samples and new interfaces.
Strict Privacy & Zero Tracking
Your microphone audio never leaves your browser tab. We don't record or sell user audio data. Clean code built with integrity.
A Note from Raj
Creator & Developer of Ukulele Tuners
"I built Ukulele Tuners because I was tired of download-heavy app store tuners that constantly push paid upgrades just to tune 4 simple strings. I wanted something clean, instant, accurate, and completely free that anyone with a browser can open in seconds. If this tool brings a smile to your face or helps your practice sessions, thank you from the bottom of my heart for your support!"

Do I need a Buy Me a Coffee account to donate?▼
No account is required! You can complete a one-time tip in under 30 seconds using Apple Pay, Google Pay, credit/debit card, or PayPal.

Yes! Buy Me a Coffee has an open message box where you can leave personal feedback or request specific tunings (like D-Tuning, Low A, or custom instruments). I read and respond to every note.
