SignalCheck is the proud result of thousands of hours of development and testing by one individual. What started as a small side hobby somehow evolved into a surprisingly popular app! SignalCheck Pro has a small cost, but it is a one-time purchase that includes support and updates for the lifetime of the app.

Many users have asked for the ability to make additional donations to the developer; not to purchase anything extra, but simply to express gratitude. A secure donation portal through PayPal is now available below. Please understand that donating is optional and you will receive nothing in return other than the satisfaction of knowing you have helped support this project.

Your contributions are graciously appreciated, and will help fuel the motivation that triggered this project in the first place. Thank you!
