WallConnectorLog is free, and stays free.
No ads, no in-app purchases, no analytics, no accounts, and nothing in the app is behind a payment. If you feel like giving back, here are the ways — but the app is exactly the same either way.

One-off or monthly, and it shows up next to the code.

Putting a free app on the App Store requires the Apple Developer Program, 99 USD a year. Anything beyond that is a thank you, not a budget.
The app only shows what WallConnectorLog the server has already logged. That is where the around-the-clock work happens, and it is free and open source too.
