The calendar day does not always coincide with a person’s working day. The important question is how to check off an action after midnight and which shift or day the record belongs to.
One of the most feature-complete trackers: widgets for iPhone and Apple Watch, daily and weekly habits, a timer, and retroactive logging of missed days. The ring-style day indicator is clear without being cluttered.
評価点：Widget that lets you log without opening the app. Apple Watch with daily progress. Retroactive logging of missed days. Built-in habit timer. One-time purchase with no monthly renewal.
不満点：Apple Health syncs in one direction only: from Health into the app, not back. When iCloud has issues, sync breaks silently.
向いている人：Anyone who wants a fully native iOS tracker with Apple Watch and widgets, without a monthly subscription.
One of the cleanest trackers: colored tiles by day create a visual chain you do not want to break. A widget lets you log a habit right from the home screen with one tap. You cannot fix a missed day retroactively.
評価点：The widget lets you log a habit from the home screen in one tap without opening the app. A color heat map by month clearly shows completion density rather than just a streak.
不満点：You cannot mark a habit retroactively: a missed day is lost forever. No flexible scheduling like 'three times a week' without a daily counter. The free plan is limited to three habits.
向いている人：People who want to see their habit history as a heat map and value instant widget logging.
One of the best trackers in the 'simple and visual' class: all logging is one tap, monthly history is visible at a glance, retroactive filling of missed days works. The developer responds to reviews and ships updates. No aggressive subscription barriers. The only known bug is limited reminder-time customization when creating a new habit.
評価点：One-tap logging with haptic feedback. Retroactive filling of past days without limits. Dark interface, no visual noise. More than six years of stable operation according to reviews.
不満点：Reminders when creating a habit are tied to the current time rather than any chosen time. No iPad or Mac version.
向いている人：Anyone who wants a clean visual tracker without subscription pressure and with the ability to log yesterday.
