The tracking capabilities are nice and it's simple enough to be likeable by most people. However  for me I needed it to track my habits through notification actions and to be able to do custom scheduling. Both of these failed: when marking an habit as ""Done"" while on the lockscreen (my main use-case)  it hasn't registered on the stats once; scheduling a reminder for select weekdays results in both missing notifications  while also firing them on unselected days. It could've fit my case perfectly and allow me to have near-seamless reminders of habits  while allowing me to track track them and serve as incentive.
