Hi, I'm joshua stein, the proprietor of Pushover. 10 years ago this week, I officially launched the Pushover app on the Apple App Store and Google Play (back then called Android Market) and since then, support for Pushover's API has been integrated into countless services, products, open-source libraries, and one-off shell scripts and tools. To date, Pushover has delivered over 3 billion notifications to over 3/4 of a million users.
