Hey HN, I made this after working from a coffee shop when I happened to notice my battery was already at 50% – after just an hour. Turns out one of the browser tabs I had open was using 100% CPU. It&#x27;d been going on for awhile so the fan was spinning like crazy but I couldn&#x27;t hear it over the noise in the shop.<p>So what the app does is it lets you know when a program starts draining your battery so you can close it and save battery power. Specifically, it triggers a notification when any process uses x% CPU or consumes y gigabytes of memory for z seconds (you choose the x, y, and z values).<p>This is the first piece of software I&#x27;ve written that isn&#x27;t a web app and the first release I&#x27;ve felt comfortable sharing widely. Any feedback would be greatly appreciated.
