Karma should work more like Fitbit
I left a criticism of Karma on Facebook a while back and was asked to leave my suggestions on how it can be improved so I am doing so now. My criticism was that all the benefits of using karma to encourage momentum is hidden behind something you need to click.
I use fitbit in my title because I thought it would be a nutshell, attention grabbing description of my issue.
If you can measure it you can't manage it. I would add if you can't see it then it is out of sight out of mind especially for a tool that is visual in nature.
I recommend that Todoist go beyond the boring display of lists that is duplicated in almost every to do app and go to visual summaries that allow one to zoom into detail. I created my own personal version of a to do list several years ago and what worked for me is a more interactive approach.
1) Integrating gaming elements like badges and visual displays of accomplishments.
2) Completing a task should trigger a status of tasks remaining just for that day or display of the time for a must do calendared task. For example - "Your next task is at 3pm" or "3 of 5 tasks due today completed 2 more left" (sure it could be said better) to drive a future focused mindset.
3) Maybe getting Karma on mobile.
4) I would like a graphical display and status of how my day is going compared to yesterday so I can be "stronger than yesterday" and also for the week/last 7 days
5) A summation of my task progress with fellow team members to create competition. Task completion count is an easy display that doesn't need to reveal private task info.
I have more ideas coming from this mindset but I think you get the gist. Text is text. A list of text is just more text in a list. Text even as you read this is not the greatest visual motivator. It takes too much time to mentally comprehend the meaning and even when you do you will rarely reread it.
You are dealing with a visual medium and increasingly so when you got to mobile. Give me meaning of my life through my tasks by making them more meaningful with visual, comparative, and interactive elements or wait for some other company to beat you to it.
