7 Caps is a compact and straightforward indicator utility that displays number/caps lock status in real-time.
7 Caps will be a money saver when the indicator lights on your current keyboard or laptop are not functioning, saving you on repair or replacement or if you want a heads-up verification of functional status. This status will be helpful when typing a passage from a website onto a local document, for instance. But that's not all; you get some mild customizations that allow you to set sounds when the caps/num locks are turned on or off, further streamlining the status check process.
7 Caps is exceptionally straightforward to set up and use and comes in a portable edition, so you can always have it with you. Keep in mind that an app that tracks key input will undoubtedly get some VirusTotal hits which will usually be a false positive - for more info on false positives.
