Several first-party apps are noticeably missing from Apple Watch, with Reminders and Podcasts being probably the most obvious. I'm confident Apple will bring these apps to Apple Watch sooner than later, but we're left dealing with workarounds and third-party apps to fill our needs for the time being.
Reminders Nano is one of these apps that picks up where Apple left off. Bringing a comprehensive yet simple reminders app to Apple Watch, Reminders Nano looks like something Apple itself would have shipped.
