Count without looking. Counter1234 is a counter for the moments when your eyes are busy elsewhere: traffic surveys, reps at the gym, birdwatching, people at a door. ■ Count with the volume buttons Press the volume buttons on the side of your phone to count up or down. It can stay in your pocket, on the table or in your hand — you never have to look. A short vibration confirms every count. ■ Buttons set to any value +1, −1, +10 and −10 sit along the bottom of the screen, and each one can be set to the step size you need. ■ Undo Take back the last change. A mis-tap no longer costs you the whole count. ■ 100 memory slots Give a count a name and save it. Up to 100 slots, ready whenever you need them. ■ CSV export Export your records as a CSV file and open them straight in Excel or Numbers. ■ Full screen Just the number, big enough to read across a room. ■ Stays out of your way The count survives closing the app. Light and dark themes. An option to keep the screen awake during long counts. Available in 10 languages. ■ Remove the ads A single purchase in Settings removes every ad, permanently. Free.
