Countly is a minimalist habit tracker and tally counter for iPhone and iPad, with a companion app in your Mac's menu bar. Build routines you can finish in a tap. Check a habit off once a day, or count toward a daily goal such as glasses of water, pages read or reps. Watch the ring fill, keep your streak alive and look back at how far you have come. KEY FEATURES • Two kinds of routines: check-in routines you complete once a day, and counting routines with a daily goal. • Current streak, best streak and success rate for every routine. • Today: what is left, what is done and your progress at a glance. • Insights and history: browse any routine by month or year in a calendar, with a 7-day summary and a 30-day chart. • More than 100 icons and ready-made templates make each routine your own. • Daily reminders for any routine. • iCloud sync keeps your routines in step across iPhone, iPad and Mac. • A two-column layout that makes the most of iPad and other wide screens. • Optional tally sounds when you count. Coming from an earlier version? Your counters become daily counters, with their names, icons and history kept.
