Summary
Mieru Day is a planned day planner that lays out your day as time blocks and shows the remaining time of your current task shrinking, including on the Lock Screen, so time becomes easier to see. It is designed mainly for people who find it hard to sense time, including people with ADHD.

Who it is for and what problem it solves
When time is hard to sense, it is hard to know how many minutes are left, so people run late or cannot switch tasks. Visual planner apps exist, but many lock key features behind a paid plan, and users say this makes them hard to keep using.
- Clock numbers alone do not make remaining time feel real
- Rebuilding routines such as getting ready in the morning every day is exhausting
- Popular visual planners repeatedly push a paid plan once you start using them
