I'm not a person who makes to-do lists because most software and apps that I've checked are too bulky and not very visually appealing. The google tasks app that I currently use doesn't really help me plan my day efficiently.

The simpler app solves both my issues. The interface is very visually appealing and it makes it easier for my eyes. It's the perfect amount of minimalism and I love the zen mode. Also, unlike google tasks, Simpler lets me set the time it takes to complete tasks. Instead of making a random list, I get to think a tiny bit to decide how much time it will take to complete a task. Which is SUPER SUPER helpful. For the past 2 days, I've been less stressed and less overwhelmed since I've been able to quantify the amount of time it will take for me to finish a task, so I never end up giving myself more work than I can handle.
I really like the app, and I would love to see it improve in the future.

Few features that I'd like to see:

1. a visual graph to see how much time it will take to finish all my tasks for a certain category. Like, I would like to know how much time it will take in total to finish all the to-dos assigned for work, so I can know whether I can add more to-dos or I'm full for the day.

2. Ability to add custom durations. Currently, the app has all the good intervals until 1 hour, and then it has increments hour by hour. I would like to tell that a certain task would only take 1 hour and a half, or 1 hour and 20 minutes.

3. An Android app + widget

4. Better functionality on Firefox. The app has been glitchy on firefox, the to-dos keep jumping up and down with no way to stop them. Not a major issue and I'm sure it can be fixed easily. Works mostly fine on chrome

5. Faster backend

Over and all, it's the best to-do list app for me. Simple, efficient, and stress-free ^^
