Hi! I’m testing a mobile app called String Mapper, designed for photovoltaic installers.

The app helps organize and trace PV module serial numbers by linking each scanned module to the correct installed string, making commissioning, documentation, maintenance and future fault tracing much easier.

I’m currently running a closed test through Google Play and need testers to install the app and keep participating in the test for at least 14 days.

The app works offline, uses barcode scanning and allows the mapping records to be exported as CSV.

If you can join the test and try the app, your feedback would be very useful.
