A Tale of Two Alert Schemes

So I built a nice budget app for Android and iOS. A core feature is sending you an alert when a bill is nearly due. Each platform required a very different approach to reliably schedule and trigger those notifications. This… is that story. Scheduling stuff is hard Have you ever received an alert from an app for something you deleted? For example, you keep getting a reminder to pay your “Doggie Daycare” bill, but you don’t even have a dog anymore?
