Myself App is for you. It contains a few different features:

- Time Tracking: Track your time conveniently using different labels
- Todos: Small compact list with basic check mechanism
- Traits: Write down your traits, you can get a reminder for them
- Bucket List: Write down all the things you've always wanted to do
- Diary: Super simple diary, which can also be used as a note keeping tab

There might be more coming in the future. Things might change. I don't know which way this app will develop itself.

For sure you can use it for self-improvement & self-development though!
