A few issues I noticed – Habit HQ – Your daily habit tracker Review

Only tracks one habits without an in-app purchase—most other free apps in this category track three. Although there is a daily notification (at 6pm), there are no custom reminders for each habit. The prominent Share button doesn't (as you might think) share your current habit and progress—instead, it shares a link to the app in the App Store. I'm not sure if skipping days (marking a day neither Yes nor No) is an actual feature, but if you accidentally marked a day one way or the other you cannot go back and unmark it. If skipping days wasn't intended, then marking No is hardly necessary. Tracking is limited to daily habits, and then only to once a day.
