Useful Counters & Countdowns vs HeliTool

Count anything, follow your habits and watch the days go by. Useful Counters keeps it simple: create the counters you need, give them an icon and a color, and read everything at a glance on a single screen. THREE TYPES OF COUNTERS • Simple button counter The simplest one. Tap to add, subtract or reset. Perfect for keeping the score of a game, counting leaflets handed out, people at the door or rows of stitches. • Daily button counter The same buttons, but every tap is stored with its date. You immediately see the total for the day, the week, the month and the year. Ideal for glasses of water, workouts, medication, remaining holidays or anything you want to follow over time. • Countdown Pick a date and a time and see the years, months, days, hours and minutes left before the event, or elapsed since it happened. It can repeat every week, month or year for birthdays and anniversaries, and be added to your calendar. GOALS, STATISTICS AND REMINDERS • Set a goal: at least 8 glasses of water a day, at most 3 coffees, per day, week or month • Follow your progress bar and your streak of days in a row • History charts by day, week or month, with the total, the average and your best period • A daily reminder when you have not counted yet, and a notification on the day of a countdown • Made a mistake?
