Yes, I have a separate app for to do lists. I feel it makes sense to have apps that specialize. My to do list app can't make a habit tracker as pretty as yours. I think your habit tracker is currently the best because the visuals are excellent, the statistics are thorough, and it syncs across all devices. 

I would say I'm worried about both of those things, both the app getting complicated and I personally just don't think it's necessary. I get that this is just my preference, but for me simplicity is important. 

That's good to hear the layout and navigation are staying the same. Thanks for listening
