Is there a free harmonica bend trainer?

Yes. Cyber Harp's Bend Lab runs free in any browser with a microphone, no download or account required. It grades your pitch live against the target note instead of leaving you to guess by ear.

How do I know if my harmonica bend is actually in tune?

Your ear alone is unreliable in the first weeks - a bend can sound close and still sit 30-40 cents flat or sharp. A pitch-detection tool listens through your microphone and shows the exact cents offset, so you get a verdict instead of an impression.

What should a good harmonica bend trainer measure?

Three things: the target pitch for the specific hole and depth you are bending, how close you actually landed in cents, and whether you held it steady rather than wobbling through it. A tool that only shows a generic tuner needle without a bend-specific target misses the second part.

Do I need to download an app to practice bending?

No. Several bending trainers require an app store install, but Cyber Harp's Bend Lab runs directly in your browser using the Web Audio API - open the page, allow microphone access, and start playing.
