At this time the forms in HomeGauge only work in the full desktop software. Making form fields fillable on the HG Companion is planned for a future version, but we do not currently have an ETA on this feature.
After you have finished your report on your Companion app, send the report to the Cloud and transfer it down to your computer. Open the report. From there you can click the Misc. button on the left side of the screen. Choose Forms and add the forms you'll need for your inspection prior to upload.
