Really helpful app – Online Piano Atlas Review

I use this app regularly to find out more information about pianos. I am a professional piano technician, and the OPA is very helpful in the field when making decisions about repairs. Thanks to the developer. The only issue I’ve had is when the serial number contains letters, the results often come back as “no such serial number exists...” so if that glitch were worked out it would be even better.
