To browse this website, you should unconditionally agree to its terms and conditions. If not, please stop and leave now. And, why is this site black? Reading black text on a white background is like staring at a lit bulb at close quarters. This website uses soft light to display the text and turns off the background.
WARNING: This app may be very buggy. I have no plans to update or fix it.
Subhash SiteChecker app can be used to monitor websites and keep track of their uptimes. Once started, the app runs in the background and monitors specified websites. If a link downtime is detected, then the app displays notifications and/or sends messages to specified e-mail recipients if required. The app is not dependent on any web service and is entirely self-contained. It is free for personal/commercial use. As with all my apps, it displays no ads and contains no nags.
