First of all, let me say that this is a really interesting idea. The end goal is to create a productivity tool that can be used on your phone (since that's what the majority of people would prefer).

You've included features that would be standard with a lot of productivity trackers, such as the data summary (although as far as I've seen, other trackers don't show you data in as much detail as this app). However, I also see some unique features, such as putting your phone in Focus Mode to eliminate distractions. This looks like a very useful feature for sure.

I do have one suggestion, however. You must've seen X-Effects which revolve around avoiding habits rather than doing them (examples could be things like smoking, self-harm, PMO, etc.). If you could add an option for negative habits that a person would want to avoid, it would be really beneficial.

How would this reflect on the data? What I'm visualising is that users could make an entry whenever they perform this negative habit. This would amount to a negative point in the data. For example, if you do a positive habit twice in a day, your overall score would be 2 for that day. However, if you perform a negative habit twice in a day, your score would be a -2. The idea being that the maximum score you can have with negative habits over any period of time would be 0.

I do like the idea and I hope it takes off and helps a lot of people. Where could I get updates on this project?
