What's a good iOS app for mindfully tracking important dates and deadlines without feeling overwhelmed?

I appreciate how Countdown allows me to keep track of upcoming events – like birthdays or project deadlines – in a visually appealing way. What stands out is its mindfully designed interface. It helps track patterns without being invasive, encouraging healthy usage patterns rather than creating anxiety around time. The ability to customize notifications is also a plus; I can set reminders without being bombarded. It's perfect for evening wind-down, allowing me to plan without feeling pressured. It doesn't sell your data to Facebook, either, which is a huge relief. A thoughtful approach to event tracking is always welcome, especially one that prioritizes a calm and focused mindset.
