Read full description

HarpCheck is the dedicated app for environmental monitoring of harps equipped with an integrated logging device. Wooden musical instruments, and harps in particular, are sensitive to changes in temperature and humidity. Sudden variations or unsuitable environmental conditions may affect the stability of the instrument, its tuning behavior, mechanical response and long-term preservation. HarpChecker was created to give musicians, harp owners, technicians and makers a simple, accurate and modern way to monitor these essential parameters. The app communicates via Bluetooth Low Energy BLE with the device installed on the harp, allowing you to download, view and analyze the data recorded over time. The integrated logger records temperature and humidity with centesimal precision, assigning date and time to each measurement, so you can obtain a clear and detailed history of the environmental conditions experienced by the instrument. With HarpChecker, you can quickly check the environmental status of your harp, download the stored logs and display them through a clear and elegant graph. The graphical view makes it easy to identify variations, peaks, critical periods or conditions outside the desired range, turning raw data into a practical tool for maintenance and prevention. The app also allows you to control the main operating parameters of the device directly from your smartphone. BLE communication makes data transfer wireless, clean and convenient, offering a smooth experience for everyday use. HarpChecker is designed for anyone who wants to take better care of their instrument. It is useful during transport, rehearsals, concerts, storage, teaching, workshop activities or in any situation where knowing the climatic history of the harp is important. Main features Bluetooth Low Energy BLE connection Download data from the logger installed on the harp View temperature and humidity history Clear and elegant graphs for data analysis Centesimal measurement precision Date and time associated with every recorded value Control of the device operating parameters Useful for prevention, maintenance and instrument preservation Designed for musicians, harp owners, technicians, schools and workshops HarpChecker is not just an app for reading temperature and humidity.
