SEKONIC LD offers upgrade option with in-app purchases (3-month subscription, 12-month subscription), including a 2-week free trial. With the upgrade, you can import drawings such as lighting layouts or site photos, and link measured values directly on them. Even if you stop the measurement midway, you can add notes to the saved data, making it convenient for multiple measurements. You can also attach smartphone images and notes to each measurement data. Location information of sites can also be attached with GPS data. Compile project data into simple reports, output as PDFs, or export as CSVs for further processing.

Verdict
The clearest difference is in-app purchases: P&B Master at none against SEKONIC LD's 2. P&B Master also leads on update cadence (every 5 weeks vs every 9 months) and iOS requirement (13.0 vs 16.0). On price, ads and device support there is nothing between them.
